Aerogel Can Become the Key to Future Terahertz Technologies


High-frequency terahertz waves have great potential for a number of applications including next-generation medical imaging and communication. Aerogels could be a nice addition to this. 

Researchers at Linköping University, Sweden, have shown, in a study published in the journal Advanced Science, that the transmission of terahertz light through an aerogel made of cellulose and a conducting polymer can be tuned. This is an important step to unlock more applications for terahertz waves

The terahertz range covers wavelengths that lie between microwaves and infrared light on the electromagnetic spectrum. It has a very high frequency.

Thanks to this, many researchers believe that the terahertz range has great potential for use in space exploration, security technology and communication systems, among other things. In medical imaging, it can also be an interesting substitute for X-ray examinations as the waves can pass through most non-conductive materials without damaging any tissue.

However, there are several technological barriers to overcome before terahertz signals can be widely used. For example, it is difficult to create terahertz radiation in an efficient way and materials that can receive and adjust the transmission of terahertz waves are needed.

Adjustable filter

Researchers at Linköping University have now developed a material whose absorption of terahertz signals can be turned on and off through a redox reaction. The material is an aerogel, which is one of the world’s lightest solid materials.

“It’s like an adjustable filter for terahertz light. In one state, the electromagnetic signal will not be absorbed and in the other state it can. That property can be useful for long-range signals from space or radar signals,” says Shangzhi Chen, postdoc at the Laboratory of Organic Electronics, LOE, at Linköping University.

The Linköping researchers used a conducting polymer, PEDOT:PSS, and cellulose to create their aerogel. They also designed the aerogel with outdoor applications in mind. It is both water-repellent (hydrophobic) and can be naturally defrosted via heating by sunlight.

Large modulation range

Conducting polymers have many advantages over other materials used to create tunable materials. Among other things, they are biocompatible, durable, and have a great ability to be tuned. The tunability comes from the ability to change the charge density in the material. The great advantages of cellulose are the relatively low production cost compared to other similar materials and that it is a renewable material which is key for sustainable applications.

“The transmission of terahertz waves in a broad frequency range could be regulated between around 13 % and 91 %, which is a very large modulation range,” says Chaoyang Kuang, postdoc at LOE.

The study was funded by, among others, the Swedish Research Council, the Foundation for Strategic Research, the Foundation for Internationalization of Higher Education and Research, the Knut and Alice Wallenberg Foundation, the Wallenberg Wood Science Centre, and through the Swedish government’s strategic initiative in new functional materials, AFM, at Linköping University.

Facts: The terahertz range covers the wavelengths that lie between microwaves and infrared light on the electromagnetic spectrum. The waves have a width of between 0.1 and 1 millimetre and the frequency is at least 0.3 terahertz and at most 30 terahertz. 1 terahertz means that 1000 billion waves are sent or received in one second.

Heightened tensions in the Red Sea: A complex context between the conflict in Yemen and the war in Gaza

0

The rise in tensions in the Red Sea, marked by numerous attacks on merchant shipping carried out by Yemeni rebels supported by Iran, adds a new complex dimension to regional dynamics. The Houthis say they are targeting ships linked to Israel as a sign of solidarity with Gaza, intensifying tensions.

Recent US-British strikes on military sites in the hands of the Houthis, including in Sanaa, revive fears of a regional spillover of the war in Gaza triggered by the unprecedented attack by Hamas on Israeli soil on October 7. These strikes reactivate concerns of a broader conflict, intertwining the situations in Yemen and Gaza.

The Houthis, also called Ansar Allah, are a Zaidi rebel group, a branch of Shiism, which has taken control of large areas of Yemen, including the capital Sanaa. Their ideology is anchored in a mixture of religious, political and social demands, highlighting the defense of the rights of the Zaidis and opposing Saudi influence in the region.

In response to the airstrikes, the Houthi Supreme Political Council declared that all US-UK interests are now legitimate targets for Yemeni armed forces, further highlighting the interconnectedness of conflicts in the region and raising questions about possible repercussions beyond the immediate theater of hostilities.

The complexity of the geopolitical landscape is heightened by the close links between conflicts in the Red Sea, Yemen and Gaza, creating an interconnected web of regional tensions. Rapid developments on these multiple fronts highlight the need for a sensitive approach to mitigate potential risks of destabilization in this part of the world.

In this context, the earlier war waged by the Arab Coalition in Yemen a few years ago takes on new relevance. Despite the coalition’s efforts to weaken the Houthis, the latter maintained their hold over vast territories, illustrating the resilience of their movement. This continued resistance raises questions about the capacity of the international community to sustainably influence the balance of power in a region marked by persistent conflicts.

The implications of these complex and interconnected developments extend beyond regional borders, requiring careful international coordination and diplomacy to prevent further escalation and foster stability in this geopolitically sensitive area.

At the award ceremony today in Vilnius, European Parliament President Roberta Metsola thanked the Seimas, the Lithuanian Parliament, for its decision to honour the European Parliament with the 2023 Freedom Prize.

President Metsola said in her keynote speech marking the Day of Defenders of Freedom:

“This award does the European Parliament a great honour. It will inspire us to continue our support of democracy. It will inspire us to stand up for Europe. Lithuania knows only too well what is at stake. Why we need Europe to stand up for our freedoms and our values. Why we must stand firmly for Ukraine. Why Europe must be the light that the world sees.”

On 23 November 2023, the Seimas awarded the European Parliament and Petras Plumpa, political prisoner and participant in the Lithuanian unarmed anti-Soviet resistance, with the 2023 Freedom Prize of the Republic of Lithuania.

The European Parliament received the Prize for its current efforts to consolidate democracy and human rights, for defending the right of nations to sovereignty, for its unrelenting efforts towards historical justice, for supporting the cause of Lithuania’s freedom and the aspiration of the Soviet-occupied Baltic States towards independence, for the diplomatic assistance to Lithuania that restored its independence, and for its contribution to EU integration. As far back as 1983, the European Parliament adopted a resolution condemning the Soviet Union’s occupation of the Baltic States.

President Metsola´s visit to Lithuania kicked off a series of visits to Member States to ‘Get out the vote’ in the run up to the European elections on 6-9 June. During her visits, the President meets with the country’s leadership, and holds town hall discussions with young people and civil society representatives to highlight the importance of election participation and strengthening democracy.

President Metsola awarded the Grand Cross of the Order of the Lithuanian Grand Duke Gediminas

On Friday 12 January 2024, President of the Republic of Lithuania Gitanas Nausėda awarded the Grand Cross of the Order of the Lithuanian Grand Duke Gediminas to the President of the European Parliament Roberta Metsola “for her leadership and personal will to effectively consolidate strong support of the majority of the European Parliament’s political groups on key issues relevant to the European Union’s and Lithuania’s political agenda”.

President Metsola wholeheartedly thanked President Nauseda and the people of Lithuania for the prestigious award:

“It serves as a constant reminder of our duty to defend democracy, freedom and our common European values.”

Background

The Freedom Prize of the Republic of Lithuania is awarded every year on 13 January, the Day of the Defenders of Freedom, to mark the events of 13 January 1991, when Soviet troops stormed the Lithuanian Parliament, the TV Tower, and the Lithuanian Radio and Television building, killing 11 peaceful citizens and injuring hundreds of others.

The Freedom Prize was established in 2011 to honour individuals and organisations for their achievements in and contribution to the defence of human rights, development of democracy, and promotion of international cooperation for the cause of self-determination and sovereignty of the nations in Central and Eastern Europe.

Gaza crisis: aid agencies warn of ‘tragic, avoidable surge’ in child deaths

Gaza crisis: aid agencies warn of ‘tragic, avoidable surge’ in child deaths

“About 160 children are killed every day; that’s one every 10 minutes,” said UN World Health Organization (WHO) spokesperson Christian Lindmeier, echoing concerns from the UN Children’s Fund about the serious additional threat of a mass disease outbreak in the enclave.

“If youngsters continue to have restricted access to water and sanitation in Gaza, we will see a tragic yet entirely avoidable surge in the number of children dying,” UNICEF spokesperson James Elder told journalists in Geneva, who noted that more than 5,350 Palestinian children had reportedly been killed, according to the enclave’s health authorities. 

“The death toll among children is sickening,” Mr. Elder said. “Grief is becoming embedded in Gaza. So this then is a stark warning: without sufficient fuel, without sufficient water, conditions for children will plummet.”

The UNICEF spokesperson added that at least 30 Israeli children are still being held hostage “somewhere in this hellscape”, before appealing for their immediate release, to spare them “their fear (and) the torment” their families have endured.

Hospital evacuation planned

Speaking to journalists in Geneva, WHO’s Mr. Lindmeier explained that “every 10 minutes, two children are injured”, while youngsters and their families caught up in the conflict have been dying “in terrifying circumstances”.

According to the UN health agency, around 180 babies are born every day in the war-shattered enclave. More than 20 of them need specialized care, just like the infants from Al-Shifa hospital in Gaza City, where 31 premature and low-birthweight babies in intensive care were evacuated over the weekend. The original number of infants was 33 but two died “because of the lack of care available to them,” Mr. Lindmeier said.

Highlighting the dire situation all over Gaza where “less than half” of the enclave’s hospitals and clinics now function “in any capacity”, the WHO official said that plans were continuing to evacuate the remaining 200 patients and 50 health workers from Al-Shifa hospital, as a desperate, last resort.

Facing ‘certain death’

“When these people – the doctors, the nurses, the patients – are asking to be evacuated, that’s really the last resort,” he said, adding that it meant “that the situation on the ground has grown so dire that the only other alternative is facing what they think certain death”. 

The WHO spokesperson explained that such evacuations were extremely complicated and dangerous, requiring coordination with Israeli Defense Forces and with Hamas “to get to a safer place inside Gaza”.

The evacuation teams will “need time, they need preparation, they need specialized equipment, they need safe passage”, Mr. Lindmeier said.

Almost no water, fuel, food

According to the UN health agency, Gaza is now home to thousands of injured and critically ill people. There has been a sharp increase in diseases such as diarrhoea, and respiratory infections, along with “almost no water, fuel, food, electricity, or medical supplies”.

Some 72,000 cases of upper respiratory infections have been reported in displacement shelters with close to 49,000 cases of diarrhoea and over half of these among children under age five. This compares with a pre-war monthly average of 2,000 cases in 2021, 2022

Arrival of medical staff and equipment

Speaking later in New York, UN Deputy Spokesperson Farhan Haq said around 40 trucks carrying medical equipment, alongside 180 doctors and nurses, entered Gaza on Monday for the establishment of a second Jordanian field hospital in the southern city of Khan Younis. The facility will have 150 beds.

He also reported that the Indonesian Hospital in Beit Lahiya, northern Gaza, came under attack on Monday.  Twelve people were reportedly killed, including patients and their companions, and many others were injured. 

This marked the fifth time the hospital has been hit since the start of hostilities last month.

“Hospitals and medical personnel are specifically protected under international humanitarian law and all parties to the conflict must ensure their protection. Hospitals must not be used to shield military objectives from attack,” he said.

The UN agency that assists Palestine refugees, UNRWA, further reported that nearly 93,000 displaced people are sheltering in 156 of its facilities across all five governorates in the Gaza Strip, including in the north.

UN at the ready

Meanwhile, international media have been reporting on the possibility of a deal between Israel and Hamas that would involve a hostage exchange and a cessation of fighting for four or five days.

Asked about UN humanitarian response in the event of a possible ceasefire, Mr. Haq said it was “a little bit premature” to talk about the issue.

“But certainly, what we are doing is trying to make sure that we are ready, so if there is any pause in fighting, which is what we’ve been asking for, we would be able to deliver humanitarian aid more effectively,” he said.

WHO staff member killed

The World Health Organization (WHO) mourned the death of a staff member who was killed in Gaza on Tuesday.

Dima Abdullatif Mohammed Alhaj, 29, worked as a patient administrator at the Limb Reconstruction Centre, a critical part of the WHO Trauma and Emergency Team, and had been with the UN agency since December 2019.

Ms. Alhaj had evacuated from Gaza City to her parents’ house in the south, which was bombed on Tuesday.

She was killed alongside her husband, six-month old son, and two of her brothers. Reportedly, over 50 family and community members sheltering in the same house also died.

“She was a wonderful person with a radiant smile, cheerful, positive, respectful. She was a true team player. Her work was crucial, and she had been requested to take on even more responsibilities to support the Gaza sub-office and team,” said Dr. Rik Peeperkorn, WHO representative in the occupied Palestinian territory.

He expressed deepest condolences to her mother and father, a long-serving medical specialist in Gaza, as well as to her family and many friends.

WHO noted that the humanitarian community and the UN have suffered losses since the start of the conflict.  Two doctors from the medical charity MSF were also killed on Tuesday while UNRWA has lost 108 colleagues to date.

“The death of Dima and her family is another example of the senseless loss in this conflict,” said WHO.  “We plead again with all those who hold in their hands the power to end this conflict to do so.”

Back to Gas: Teslas Too Expensive for Hertz, Other EVs Too


Rental giant Hertz is divesting approximately 20,000 electric vehicles, including Teslas, from its U.S. fleet, opting for gas-fueled cars instead.

This move comes around two years after entering a deal with Tesla to provide its vehicles for rent. This move signifies a downturn in demand for electric vehicles (EVs), experts say.

Hertz has decided to shift its focus to gas-powered vehicles, citing increased expenses associated with collision and damage for EVs. Despite initially aiming to transition 25% of its fleet to electric by the end of 2024, the company has reassessed its strategy.

CEO Stephen Scherr last year highlighted challenges arising from elevated expenses for its EVs, particularly Teslas. To mitigate issues, Hertz even restricted torque and speed on the EVs, making them available to experienced users on the platform to enhance adaptability after certain users experienced front-end collisions.

The company’s shares, which also include vehicles from Swedish EV maker Polestar among others, experienced a decline of approximately 4%. Concurrently, Tesla’s stock saw a decrease of about 3%.

Hertz anticipates incurring approximately $245 million in charges attributed to depreciation expenses resulting from the EV sale in the fourth quarter of 2023.

While consumers appreciate the driving experience and per-mile fuel savings of an EV, there are other “hidden costs to EV ownership.” Hertz acknowledged in a regulatory filing on Thursday that expenses related to collision and damage, primarily associated with EVs, remained elevated in the quarter.

The company, which initially aimed to acquire 100,000 Tesla vehicles by the end of 2022 and 65,000 units from Polestar over five years, has shifted its focus towards enhancing profitability for the remainder of its electric vehicle (EV) fleet.

Hertz’s used car website indicates the sale of certain Tesla Model 3 vehicles for approximately $20,000, nearly half the cost of the least expensive variant of the compact sedan.

The inventory includes over 700 EVs available for purchase, featuring models such as BMW’s i3, Chevrolet’s Bolt, and Tesla’s Model 3 and Model Y SUVs.

Revealing the Invisible Plot: Social Action of Minority Religious Denominations in Spain

0

In a comprehensive analysis of the social action of minority religious denominations in Spain, academics Sebastián Mora Rosado, Guillermo Fernández Maillo, José Antonio López-Ruiz and Agustín Blanco Martín, publish their revealing findings in volume 3, number 2 of “Cuestiones de Pluralismo” for the second half of 2023.

The article highlights that European society has undergone a profound transformation in its religious experience, despite the predictions of the sociologies of secularisation that predicted its demise. In this context, Spain faces unique challenges, marked by a persistent tendency to make religious diversity invisible. According to Díez de Velasco (2013), there is a deep-rooted perception that links religious diversity with foreignness and Catholicity with Spanishness.

The study, supported by the Pluralism and Coexistence Foundation, addresses the lack of public knowledge about the social action of non-Catholic religious denominations in Spain. Although some partial studies have been carried out, the research is presented as a pioneering initiative by providing a more complete vision of this social reality.

Within the framework of the research, the participation of confessions such as Buddhist, Evangelical, Bahá’í Faith, Church of Jesus Christ of Latter-day Saints, Church of Scientology, Jewish, Muslim, Orthodox, Jehovah’s Witnesses and Sikh is highlighted. The approach encompasses both quantitative and qualitative analyses to ‘map’ the social action of these faiths, examining resources, perceptions and intrinsic values.

One of the key findings is the low visibility of these social actions compared to other countries that have delved into similar analyses. The findings reveal that, in general terms, these denominations carry out their social work at the local level, with small structures and a strong involvement of volunteers. In addition, funding comes mainly from their own resources, with limited support from the public or private sector.

The article also highlights the complexity of the relationship between these denominations and public administrations. Although some denominations want specific recognition as religious entities in the field of social action, this could pose challenges in terms of secularism and freedom of conscience, as well as contradicting principles of equality in the allocation of public services.

The study underlines the importance of organised social action, focusing on basic assistance programmes and social promotion actions. It also highlights the peculiarity of the internal support that these denominations provide to their own followers, while at the same time maintaining an open commitment to those who do not share their beliefs.

One issue that hovers over the study is the perception that these social actions might be motivated by proselytising. However, focus group participants emphasise the separation between social action and proselytising, advocating the importance of attending to spiritual needs without engaging in invasive practices.

Finally, the authors conclude by pointing out the need to reverse the invisibilisation of these religious confessions and to encourage their collaboration with other public and third-sector social action entities. They consider that social action can be the privileged space to show the public and social dimension of these religious traditions, thus contributing to the construction of a post-secular, plural and democratic society. The task, although challenging, is perceived as essential to building a society where religious diversity is a real “reservoir of meaning” for citizenship.

Seamless Sojourns in Europe, Unlocking the Secrets of the Schengen Area

0

In the web of integration, the Schengen zone shines as a symbol of liberty and solidarity dismantling borders and granting European Union (EU) citizens the precious privilege of travelling without passports. Since its inception, in 1995 this borderless territory has become one of the achievements of the European project empowering individuals to live, study, work and explore freely within its boundaries. As we embark on an exploration of the intricacies of the Schengen area let us delve into the elements that make it a cornerstone of coexistence in Europe.

A Symphony of Nations; Understanding Schengen

At its essence, the Schengen area showcases the integration among EU countries. This passport-free region includes all EU member states except Ireland and Cyprus which will soon join. Surprisingly four non-EU countries—Iceland, Norway, Switzerland and Liechtenstein—also stand side by side within this agreement to offer a travel experience.

Unleashing Liberty; The Purpose and Benefits

The significance of the Schengen area extends beyond convenience; it embodies freedom. EU citizens revel in their ability to tour any member state for up to three months without needing anything, other than a passport or identity card.

The freedom offered by the Schengen area goes beyond leisure activities as it empowers individuals to live and work in any member state while enjoying the treatment, as local residents. Entrepreneurs find comfort in the freedom to establish their businesses while students appreciate the right to pursue education across EU countries.

Maintaining Security; A Borderless Approach

While the Schengen rules eliminate border controls security remains a priority. Once inside the Schengen area travelers can move freely between countries without facing border checks. However, this smooth movement is not without precautions. National authorities may conduct checks near borders based on police intelligence and experience striking a balance between freedom and security.

Addressing Challenges; External Borders

The challenges posed by increased migration flows in 2015 and subsequent security concerns led some member states to reintroduce border controls. The outbreak of the COVID-19 pandemic in 2020 further intensified this trend. Recognizing these challenges the European Commission proposed updates in 2021 to ensure that internal border controls are used as a resort. This careful approach highlights a commitment to preserving the integrity of the Schengen zone.

EU Responses; Adapting to Changing Circumstances

Dealing with migration issues and securing borders has prompted the establishment of tools and agencies, within the EU. The Schengen Information System, Visa Information System and the European Border and Coast Guard Agency (Frontex) have emerged as protectors of the Schengen principle. Moreover the Asylum, Migration and Integration Fund (AMIF) and the Internal Security Fund (ISF) play roles in addressing these challenges highlighting the EU’s commitment, to responsibility and cooperation.

Looking ahead; Future Developments

The journey towards strengthening the Schengen area does not stop here. The European Travel Information and Authorisation System (Etias) is set to play a role in improving security measures. Expected to be operational by mid 2025 Etias will screen travelers without requiring a visa serving as a prelude to their arrival in the EU. Additionally, plans are underway to reinforce the EU Border and Coast Guard Agency with a team of 10,000 border guards by 2027 showing a commitment to enhancing Europe’s security in the years to come.

As we navigate through the network of the Schengen area its importance becomes evident; it is more than a geographical region; it represents shared values, cooperation and an unwavering pursuit of a united Europe that celebrates diversity. So let borders fade away as new adventures begin within this essence of Schengen spirit.

A Breakthrough for Inclusivity, the EU Disability Card

In a groundbreaking move towards inclusivity, the Employment and Social Affairs Committee of the European Parliament has unanimously adopted a proposal for an EU Disability Card, aiming to facilitate the free movement of persons with disabilities within the European Union. The initiative also seeks to revamp the European Parking Card for individuals with disabilities, ensuring equal rights and conditions for cardholders when traveling or visiting other EU countries.

Persons with disabilities often face barriers when crossing borders within the EU due to varying recognition of their disability status. The proposed directive aims to streamline this process by introducing a standardized EU Disability Card and enhancing the European Parking Card, providing individuals with disabilities access to the same special conditions, including parking, regardless of the member state they are in.

Key Highlights:

1. Swift Issuance and Digital Options:

  • The EU Disability Card is proposed to be issued or renewed within 60 days, while the European Parking Card would be processed within 30 days, both at no cost.
  • A digital version of the parking card can be requested and obtained within 15 days, offering a convenient and efficient alternative.

2. Inclusive Accessibility:

  • Both cards will be available in physical and digital formats, ensuring accessibility for a broader range of users.
  • Rules and conditions for obtaining the cards will be made available in accessible formats, national and international sign languages, braille, and easily understandable language.

3. Recognition for Work, Study, and Erasmus+:

  • To facilitate access to benefits and social assistance, the proposal includes temporary protection for European Disability Card holders working or studying in another member state until their status is formally recognized.
  • This extends to individuals participating in EU mobility programs, such as Erasmus+.

4. Awareness and Information:

  • Member states and the Commission are urged to raise awareness about the European Disability Card and the European Parking Card, establishing a comprehensive website with information available in all EU languages and national and international sign languages.

5. Unanimous Political Support:

  • The Employment and Social Affairs Committee’s endorsement, with 39 votes in favor and no votes against or abstentions, reflects a united commitment to fostering freedom of movement for persons with disabilities within the EU.

Lucia Ďuriš Nicholsonová, the rapporteur for this legislation, emphasized the significance of this milestone, stating,

“With the adoption of this crucial piece of legislation, persons with disabilities are a step closer to having freedom of movement within the EU.”

Lucia Ďuriš Nicholsonová

The proposal will move to the January plenary session for further endorsement. Once approved, negotiations with the Council will commence, aiming to bring this legislation to fruition and provide tangible benefits for persons with disabilities at the earliest opportunity.

Relations of the Ortrhodox Church with the rest of the Christian world

0

By the Holy and Great Council of the Orthodox Church

  1. The Orthodox Church, as the One, Holy, Catholic, and Apostolic Church, in her profound ecclesiastical self-consciousness, believes unflinchingly that she occupies a central place in the matter of the promotion of Christian unity in the world today.
  2. The Orthodox Church founds the unity of the Church on the fact of her establishment by our Lord Jesus Christ, and on the communion in the Holy Trinity and in the sacraments. This unity is expressed through the apostolic succession and the patristic tradition and is lived out in the Church up to the present day. The Orthodox Church has the mission and duty to transmit and preach all the truth contained in Holy Scripture and Holy Tradition, which also bestows upon the Church her catholic character.
  3. The responsibility of the Orthodox Church for unity as well as her ecumenical mission were articulated by the Ecumenical Councils. These stressed most especially the indissoluble bond between true faith and sacramental communion.
  4. The Orthodox Church, which prays unceasingly “for the union of all,” has always cultivated dialogue with those estranged from her, those both far and near. In particular, she has played a leading role in the contemporary search for ways and means to restore the unity of those who believe in Christ, and she has participated in the Ecumenical Movement from its outset, and has contributed to its formation and further development. Moreover, the Orthodox Church, thanks to the ecumenical and loving spirit which distinguishes her, praying as divinely commanded that all men may be saved and come to the knowledge of the truth (1 Tim 2:4), has always worked for the restoration of Christian unity. Hence, Orthodox participation in the movement to restore unity with other Christians in the One, Holy, Catholic and Apostolic Church is in no way foreign to the nature and history of the Orthodox Church, but rather represents a consistent expression of the apostolic faith and tradition in a new historical circumstances.
  5. The contemporary bilateral theological dialogues of the Orthodox Church and her participation in the Ecumenical Movement rest on this self-consciousness of Orthodoxy and her ecumenical spirit, with the aim of seeking the unity of all Christians on the basis of the truth of the faith and tradition of the ancient Church of the Seven Ecumenical Councils.
  6. In accordance with the ontological nature of the Church, her unity can never be perturbed. In spite of this, the Orthodox Church accepts the historical name of other non-Orthodox Christian Churches and Confessions that are not in communion with her, and believes that her relations with them should be based on the most speedy and objective clarification possible of the whole ecclesiological question, and most especially of their more general teachings on sacraments, grace, priesthood, and apostolic succession. Thus, she was favorably and positively disposed, both for theological and pastoral reasons, towards theological dialogue with other Christians on a bi-lateral and multi-lateral level, and towards more general participation in the Ecumenical Movement of recent times, in the conviction that through dialogue she gives a dynamic witness to the fullness of truth in Christ and to her spiritual treasures to those who are outside her, with the objective aim of smoothing the path leading to unity.
  7. In this spirit, all the local Most Holy Orthodox Churches participate actively today in the official theological dialogues, and the majority of these Churches also participate in various national, regional and international inter-Christian organizations, in spite of the deep crisis that has arisen in the Ecumenical Movement. This manifold activity of the Orthodox Church springs from a sense of responsibility and from the conviction that mutual understanding and cooperation are of fundamental importance if we wish never to “put an obstacle in the way of the gospel of Christ (1 Cor 9:12).
  8. Certainly, while the Orthodox Church dialogues with other Christians, she does not underestimate the difficulties inherent in this endeavor; she perceives these difficulties, however, on the path towards a common understanding of the tradition of the ancient Church and in hope that the Holy Spirit, Who “welds together the whole institution of the Church, (Sticheron at Vespers of Pentecost), will “make up that which is lacking” (Ordination Prayer). In this sense, the Orthodox Church in her relations with the rest of the Christian world, relies not only on the human efforts of those involved in dialogue, but especially on the guidance of the Holy Spirit in the grace of the Lord, who prayed “that…all may be one” (Jn 17:21).
  9. The contemporary bilateral theological dialogues, announced by the Pan-Orthodox meetings, express the unanimous decision of all local most holy Orthodox Churches who are called to participate actively and continually in them, so that the unanimous witness of Orthodoxy to the glory of the Triune God may not be hindered. In the event that a certain local Church chooses not to assign a representative to a particular dialogue or one of its sessions, if this decision is not pan-Orthodox, the dialogue still continues. Prior to the start of the dialogue or of the session, the absence of any local Church ought to be discussed at all events by the Orthodox Committee of the dialogue to express the solidarity and unity of the Orthodox Church. The bi-lateral and multi-lateral theological dialogues need to be subject to periodical evaluations on a pan-Orthodox level. 
  10. The problems that arise during the theological discussions within Joint Theological Commissions are not always sufficient grounds for any local Orthodox Church unilaterally to recall its representatives or definitively withdraw from the dialogue. As a general rule, the withdrawal of a Church from a particular dialogue should be avoided; in those instances when this occurs, inter-Orthodox efforts to reestablish representational fullness in the Orthodox Theological Commission of the dialogue in question should be initiated. Should one or more local Orthodox Churches refuse to take part in the sessions of the Joint Theological Commission of a particular dialogue, citing serious ecclesiological, canonical, pastoral, or ethical reasons, this/these Church(es) shall notify the Ecumenical Patriarch and all the Orthodox Churches in writing, in accordance with pan-Orthodox practice. During a pan-Orthodox meeting the Ecumenical Patriarch shall seek unanimous consensus among the Orthodox Churches about possible courses of action, which may also include—  should this be unanimously deemed necessary—a reassessment of the progress of the theological dialogue in question.
  11. The methodology followed in the theological dialogues aims at both the resolution of the received theological differences or of possible new differentiations, and to seek the common elements of the Christian faith. This process requires that the entire Church is kept informed on the various developments of the dialogues. In the event that it is impossible to overcome a specific theological difference, the theological dialogue may continue, recording the disagreement identified and bringing it to the attention of all the local Orthodox Churches for their consideration on what ought to be done henceforth.
  12. It is clear that in the theological dialogues the common goal of all is the ultimate restoration of unity in true faith and love. The existing theological and ecclesiological differences permit, however, a certain hierarchical ordering of the challenges lying in the way of meeting this pan-Orthodox objective. The distinctive problems of each bilateral dialogue require a differentiation in the methodology followed in it, but not a differentiation in the aim, since the aim is one in all the dialogues.
  13. Nevertheless, it is essential if necessary for an attempt to be made to coordinate the work of the various Inter-Orthodox Theological Committees, bearing in mind that the existing unity of the Orthodox Church must also be revealed and manifested in this area of these dialogues.
  14. The conclusion of any official theological dialogue occurs with the completion of the work of the relevant Joint Theological Commission. The Chairman of the Inter-Orthodox Commission then submits a report to the Ecumenical Patriarch, who, with the consent of the Primates of the local Orthodox Churches, declares the conclusion of the dialogue. No dialogue is considered complete before it is proclaimed through such a pan-Orthodox decision.
  15. Upon the successful conclusion of the work of any theological dialogue, the pan-Orthodox decision about the restoration of ecclesiastical communion must, however, rest on the unanimity of all the local Orthodox Churches.
  16. One of the principal bodies in the history of the Ecumenical Movement is the World Council of Churches (WCC). Certain Orthodox Churches were among the Council’s founding members and later, all the local Orthodox Churches became members. The WCC is a structured inter-Christian body, despite the fact that it does not include all non-Orthodox Christian Churches and Confessions. At the same time, there are other inter-Christian organizations and regional bodies, such as the Conference of European Churches, the Middle East Council of Churches and the African Council of Churches. These, along with the WCC, fulfill an important mission by promoting the unity of the Christian world. The Orthodox Churches of Georgia and Bulgaria withdrew from the WCC, the former in 1997, and the latter in 1998. They have their own particular opinion on the work of the World Council of Churches and hence do not participate in its activities and those of other inter-Christian organizations.
  17. The local Orthodox Churches that are members of the WCC participate fully and equally in the WCC, contributing with all means at their disposal to the advancement of peaceful co-existence and co-operation in the major socio-political challenges. The Orthodox Church readily accepted the WCC’s decision to respond to her request concerning the establishment of the Special Commission on Orthodox Participation in the World Council of Churches, which was mandated by the Inter-Orthodox Conference held in Thessaloniki in 1998. The established criteria of the Special Commission, proposed by the Orthodox and accepted by the WCC, led to the formation of the Permanent Committee on Consensus and Collaboration. The criteria were approved and included in the Constitution and Rules of the World Council of Churches.
  18. Remaining faithful to her ecclesiology, to the identity of her internal structure, and to the teaching of the ancient Church of the Seven Ecumenical Councils, the Orthodox Church’s participation in the WCC does not signify that she accepts the notion of the “equality of Confessions,” and in no way is she able to accept the unity of the Church as an inter-confessional compromise. In this spirit, the unity that is sought within the WCC cannot simply be the product of theological agreements, but must also be founded on the unity of faith, preserved in the sacraments and lived out in the Orthodox Church.
  19. The Orthodox Churches that are members of the WCC regard as an indispensable condition of their participation in the WCC the foundational article of its Constitution, in accordance with which its members may only be those who believe in the Lord Jesus Christ as God and Savior in accordance with the Scriptures, and who confess the Triune God, Father, Son, and Holy Spirit, in accordance with the Nicene-Constantinopolitan Creed. It is their deep conviction that the ecclesiological presuppositions of the 1950 Toronto Statement, On the Church, the Churches and the World Council of Churches, are of paramount importance for Orthodox participation in the Council. It is therefore very clear that the WCC does not by any means constitute a “super-Church.” The purpose of the World Council of Churches is not to negotiate unions between Churches, which can only be done by the Churches themselves acting on their own initiative, but to bring Churches into living contact with each other and to promote the study and discussion of the issues of Church unity. No Church is obliged to change her ecclesiology on her accession to the Council… Moreover, from the fact of its inclusion in the Council, it does not ensue that each Church is obliged to regard the other Churches as Churches in the true and full sense of the term. (Toronto Statement, § 2). 
  20. The prospects for conducting theological dialogues between the Orthodox Church and the rest of the Christian world are always determined on the basis of the canonical principles of Orthodox ecclesiology and the canonical criteria of the already established Church Tradition (Canon 7 of the Second Ecumenical Council and Canon 95 of the Quinisext Ecumenical Council).
  21. The Orthodox Church wishes to support the work of the Commission on “Faith and Order” and follows its theological contribution with particular interest to this day. It views favorably the Commission’s theological documents, which were developed with the significant participation of Orthodox theologians and represent a praiseworthy step in the Ecumenical Movement for the rapprochement of Christians. Nonetheless, the Orthodox Church maintains reservations concerning paramount issues of faith and order, because the non-Orthodox Churches and Confessions have diverged from the true faith of the One, Holy, Catholic and Apostolic Church.
  22. The Orthodox Church considers all efforts to break the unity of the Church, undertaken by individuals or groups under the pretext of maintaining or allegedly defending true Orthodoxy, as being worthy of condemnation. As evidenced throughout the life of the Orthodox Church, the preservation of the true Orthodox faith is ensured only through the conciliar system, which has always represented the highest authority in the Church on matters of faith and canonical decrees. (Canon 6 2nd Ecumenical Council)
  23. The Orthodox Church has a common awareness of the necessity for conducting inter-Christian theological dialogue. It therefore believes that this dialogue should always be accompanied by witness to the world through acts expressing mutual understanding and love, which express the “ineffable joy” of the Gospel (1 Pt 1:8), eschewing every act of proselytism, uniatism, or other provocative act of inter-confessional competition. In this spirit, the Orthodox Church deems it important for all Christians, inspired by common fundamental principles of the Gospel, to attempt to offer with eagerness and solidarity a response to the thorny problems of the contemporary world, based on the prototype of the new man in Christ.  
  24. The Orthodox Church is aware that the movement to restore Christian unity is taking on new forms in order to respond to new circumstances and to address the new challenges of today’s world. The continued witness of the Orthodox Church to the divided Christian world on the basis of the apostolic tradition and faith is imperative.

We pray that all Christians may work together so that the day may soon come when the Lord will fulfill the hope of the Orthodox Churches and there will be “one flock and one shepherd” (Jn 10:16).

Note on the Holy and Great Council of the Orthodox Church: Given the difficult political situation in the Middle East, the Synaxis of the Primates of January 2016 decided not to assemble the Council in Constantinople and finally decided to convoke the Holy and Great Council at the Orthodox Academy of Crete from 18 to 27 June 2016. The opening of the Council took place after the Divine Liturgy of the feast of Pentecost, and the closure – the Sunday of All Saints, according to the Orthodox calendar. The Synaxis of the Primates of January 2016 has approved the relevant texts as the six items on the agenda of the Council: The mission of the Orthodox Church in the contemporary world; The Orthodox diaspora; Autonomy and the manner of its proclamation; The sacrament of marriage and its impediments; The importance of fasting and its observance today; The relationship of the Orthodox Church with the rest of the Christian world.

An icon with an image of Stalin in the Tbilisi Cathedral was covered with paint

0

An icon of St. Matrona of Moscow, which also depicts Soviet commander-in-chief Joseph Stalin, was placed in Tbilisi’s Holy Trinity Cathedral. The icon was placed a few months ago, but on the eve of the Nativity of Christ in the old style, it was moved to a more central place, where it attracts the attention of visitors. Georgian historian Giorgi Kandelaki posted photos of the icon on his Facebook page with the words: “Icon of Joseph Stalin, the initiator of the destruction of Georgia’s independence, the murderer of thousands of clergy and the creator of the Soviet totalitarian system, in the Holy Trinity Cathedral.” Another success for the Russian information war machine.”

His publication found a strong public response and the patriarchate had to comment on the case. The head of the press office of the patriarchate, Fr. Andrija Jagmaidze confirmed in a conversation with the Georgian publication CNews that Stalin is indeed depicted on one of the icons in the cathedral, but reminded that the icons sometimes have images of people who insulted or persecuted the Church. He gave as an example the persecutor of Christians Diocletian, who is depicted on the icon “St. George advises Diocletian”. According to the representative of the patriarchate, it is not the icon itself that is a provocation to the feelings of the faithful, but the drawing of attention to it on the eve of the holiday.

However, his words did not convince the outraged people, who rightly note that on this icon Stalin is not represented as a torturer, as is the case with the icon of St. George, but as a meek Christian standing humbly next to a saint. She wants to legitimize the myth of Stalin’s secret Christianity, which is particularly popular among supporters of the Soviet regime.

On January 10, the icon was covered with blue paint. Civil activist Nata Peradze published footage of the painted icon. This is the reason why dozens of supporters of one of the far-right Georgian movements with a pro-Putin orientation surrounded her home and attempted to lynch her, “finishing what the state does not do.” The police did not allow suicide. As RFE/RL’s Georgian Service reported, an angry mob swarmed the house of Georgian activist Nata Peradze on January 10 after she posted a video online showing blue paint splattered on an icon of St. Matrona of Moscow in Tbilisi’s Holy Trinity Cathedral that had recently sparked controversy because it carries an image of the Soviet dictator Josef Stalin. It was initially unclear whether Peradze had defaced the icon, but as activists of the pro-Russia Alt-Info group gathered outside her home and loudly accused her of “insulting the icon,” she admitted she threw the paint.

Georgia’s Institute for the Study of the Soviet Past has called for the icon to be removed from the central Georgian temple. They remind that the icon was placed in the temple on the eve of the 103rd anniversary of the Soviet occupation of Georgia, “which began precisely on the initiative of Joseph Stalin”, and is “an insult to the memory of the victims of Soviet Russian totalitarianism”: “During Joseph Stalin’s rule in Georgia saw the execution of hundreds of clergy, most of them pastors and parishioners of the Georgian Orthodox Church, especially during the anti-Soviet uprising of 1924 and then during the Stalinist terror of 1937-1938. during Stalin’s rule, some 80,000 clergy and up to one million citizens were executed simply for their religious beliefs,” the organization said in a statement.

However, after the paint splatter incident, the icon was cleaned and placed in an even more central location in the temple, and media access to the temple was temporarily banned “without permission”.

Meanwhile, it is clear that the icon was donated to the church in Tbilisi by the leaders of the pro-Russian Alliance of Patriots party Irma Inashvili and David Tarkhan-Muravi. It aims to revive the cult of Stalin on church grounds, so that he is presented as a patron of the church and not as a persecutor. This goal is clearly recognized by the faithful who react sharply to this provocation, especially since in the recent church history of Georgia, its most popular contemporary saint Gabriel (Urgebadze) is known for his act of protest when during the Holy Week of 1965. publicly burns a portrait of Lenin with the words: “The Lord says: Do not make for yourself an idol or any image of that which is in heaven above, that is on the earth below, and that is in the water under the earth; do not bow down to them and do not serve them.’ Lenin’s portrait was carried at a demonstration on the eve of Easter, and neither the saint nor his contemporaries could have guessed that the time would come when the images of the persecutors of the Church of Christ would occupy a place of honor in the temple.
