IZNIK, Turkey (CNS) -- Although the ancient city of Nicaea lies in ruins and the geographic center of Christianity has shifted West, Pope Leo XIV and Christian leaders gathered at an archaeological site in Turkey to celebrate the enduring faith set out in the Nicene Creed.

Orthodox Ecumenical Patriarch Bartholomew of Constantinople hosted the ecumenical prayer service and the common recitation of the Creed Nov. 28 at Iznik, site of the ancient Nicaea, about 80 miles southeast of Istanbul.

With the Greek Orthodox patriarchs of Antioch, Alexandria and Jerusalem or their representatives and with representatives of other Orthodox, Anglican and Protestant churches, Pope Leo marked the 1,700th anniversary of the Council of Nicaea -- the primary motive for his first foreign trip as pope. 

The joint recitation of the Creed did not include the phrase known as the "filioque" -- the statement that the Holy Spirit "proceeds from the Father and the Son" -- since the phrase is not used by the Orthodox because it was inserted into the Latin Creed by Pope Benedict VIII in 1014.

Recent popes, including Pope Benedict XVI, Pope Francis and Pope Leo, have omitted the phrase at ecumenical prayer services.

Standing on a platform overlooking the remains of the Basilica of St. Neophytos, now partially submerged in Lake Iznik, the church leaders took turns leading the prayers -- in English, Greek and Arabic -- and lighting candles as a Catholic choir, singing in Latin, and an Orthodox choir, singing in Greek, alternated. 

Patriarch Bartholomew, welcoming the pope and other guests, noted that "despite so many intervening centuries and all the upheavals, difficulties and divisions they have brought, we nevertheless approach this sacred commemoration with shared reverence and a common feeling of hope."

"The power of this place does not reside in what passes away, but in what endures forever," he said.

Speaking after the patriarch, Pope Leo told his fellow Christian leaders that at a time when humanity is "afflicted by violence and conflict," the world "is crying out for reconciliation."

"The desire for full communion among all believers in Jesus Christ is always accompanied by the search for fraternity among all human beings," he said. "In the Nicene Creed, we profess our faith 'in one God, the Father.' Yet, it would not be possible to invoke God as Father if we refused to recognize as brothers and sisters all other men and women, who are created in the image of God." 

Though united by faith, the Russian Orthodox Church -- the largest of the world's Eastern Orthodox churches -- was not represented at the service. The Russian church broke relations with the Ecumenical Patriarchate over the recognition in 2018 of the autonomy of the Ukrainian Orthodox Church. 

Belief in God the father, Pope Leo said in Iznik, means "there is a universal fraternity of men and women regardless of ethnicity, nationality, religion or personal perspectives."

With many of the Christian leaders, especially the Oriental Orthodox, coming from nations that recently faced or are facing war and persecution, Pope Leo said Christians must give concrete witness to their belief that all people are children of one God and therefore brothers and sisters to each other.

"Furthermore, we must strongly reject the use of religion for justifying war, violence or any form of fundamentalism or fanaticism," he said. "Instead, the paths to follow are those of fraternal encounter, dialogue and cooperation."

The pope also repeated a concern he had mentioned during a meeting with Catholic leaders earlier in the day: the risk that many Christians have departed from the Nicene Creed's firm belief in the divinity of Jesus.

"This question is especially important for Christians, who risk reducing Jesus Christ to a kind of charismatic leader or superman, a misrepresentation that ultimately leads to sadness and confusion," he said.

At the time of the Council of Nicaea, the pope said, Arius -- a priest from Alexandra in Egypt -- had denied the divinity of Christ, reducing him to "a mere intermediary between God and humanity, ignoring the reality of the Incarnation such that the divine and the human remained irremediably separated."

"But if God did not become man, how can mortal creatures participate in his immortal life?" Pope Leo asked.

The pope told the Christian leaders that sharing the same faith in Jesus and being able to recite the Creed together means there "is a profound bond already uniting all Christians."

"We are all invited to overcome the scandal of the divisions that unfortunately still exist and to nurture the desire for unity for which the Lord Jesus prayed and gave his life," the pope said. "The more we are reconciled, the more we Christians can bear credible witness to the Gospel of Jesus Christ, which is a proclamation of hope for all."

Patriarch Bartholomew told the leaders that with "the fervor of the faith of Nicaea burning in our hearts," they must "run the course" of Christian unity in fulfillment of Jesus' prayer for the unity of his disciples.

"And, finally," the patriarch said, "let us love one another that with one mind we may confess: Father, Son and Holy Spirit -- Trinity consubstantial and undivided."
 

At the beginning of the first international trip of his pontificate, Pope Leo XIV expressed hope that Turkey would become a “source of stability and rapprochement between peoples, in service of a just and lasting peace.”

Pope Leo expressed his spiritual solidarity, including prayers for the deceased and for emergency personnel.

The forum’s theme was “Artificial Intelligence and Religious Freedom: Rights, Ethics, and Innovation.” Citing remarks he had made in June, the Pontiff expressed hope “that the event may offer careful reflection to support and promote the commitment of institutions at every level, to guarantee ‘authentic religious freedom and a respective and constructive encounter between different religious communities; and that artificial intelligence may be ‘of great help to society, provided that its employment does not undermine the identity and dignity of the human person and his or her fundamental freedoms.’”

The Pope told the superiors of men’s religious institutes on November 26 that “prayer is fundamental in the existence of every consecrated person: it is the relational space within which the heart opens to the Lord, learning to ask and to receive, with trust and gratitude, his love that heals, transforms and enflames the mission.”

Although he welcomed the opportunities the digital word brings, the Pope cautioned:

I would like to emphasize that traditional instruments of communion such as Chapters, Councils, canonical Visitations and moments of formation cannot be relegated to the sphere of “remote connections.” The effort of coming together for dialogue and the exchange of ideas is an integral part of our evangelical identity.

Bishop Ivo Muser of Bolzano-Bressanone said that “the felling of the tree is not an act of disrespect, but the result of careful forest management, where tree removal is part of an active care strategy that ensures the health of the forest and control its growth.”

ANKARA, Turkey (CNS) -- Pope Leo XIV began his first papal trip speaking of dialogue, peace and thanksgiving -- referring to both the holiday and his own gratitude.

On the plane to Turkey Nov. 27, he wished a Happy Thanksgiving to the Americans among the 80 journalists traveling with him and told them, "It's a wonderful day to celebrate."

He also received from reporters two pumpkin pies and a pecan pie; he said he would share "part of it."

Pope Leo also was given a baseball bat that had belonged to 1950s White Sox player Nellie Fox.

After expressing his appreciation, the pope asked, "How did you get that through security?" 

During the flight, speaking to the reporters from the front of the economy section of the ITA Airways plane, Pope Leo said, "I want to begin by saying thank you to each and every one of you for the service that you offer to the Vatican, to the Holy See, to my person, but to the whole world. It's so important today that the message be transmitted in a way that really reveals the truth and the harmony that the world needs."

Landing in Ankara after the flight of almost three hours, Pope Leo fulfilled the dictates of protocol as a visiting head of state, meeting Turkish President Recep Tayyip Erdogan and Safi Arpagus, the head of the national religious affairs office, known as the Diyanet.

Later, addressing the president, other government officials, members of the diplomatic corps and civic leaders, Pope Leo told them, "Today, more than ever, we need people who will promote dialogue and practice it with firm will and patient resolve." 

After World War II, he said, the world came together and formed the United Nations and other international and regional organizations committed to dialogue, cooperation and conflict resolution.

"We are now experiencing a phase marked by a heightened level of conflict on the global level, fueled by prevailing strategies of economic and military power," Pope Leo said. "This is enabling what Pope Francis called 'a third world war fought piecemeal.'"

"We must in no way give in to this," the pope insisted. "The future of humanity is at stake. The energies and resources absorbed by this destructive dynamic are being diverted from the real challenges that the human family should instead be facing together today, namely peace, the fight against hunger and poverty, health and education, and the protection of creation."

In a land where most people are Muslim, but the constitution officially proclaims the nation secular, Pope Leo praised both the tolerance of religious diversity and the encouragement given to people of all religions to practice their faith.

"In a society like the one here in Turkey, where religion plays a visible role, it is essential to honor the dignity and freedom of all God's children, both men and women, fellow nationals and foreigners, poor and rich," he said.

"We are all children of God, and this has personal, social and political implications," he said, including working for the common good and respecting all people.

Pope Francis, who visited Turkey in 2014, urged all believers in God "to feel the pain of others and to listen to the cry of the poor and of the earth," the pope said. "He thus encouraged us to compassionate action, which is a reflection of the one God who is merciful and compassionate" -- as Muslims frequently repeat -- and "slow to anger and abounding in steadfast love," as the Psalms say.

Pope Leo encouraged all people in Turkey and all people of good will to defend social bonds, beginning with the family. 

"People do not obtain greater opportunities or happiness from an individualistic culture, nor by showing contempt for marriage or shunning openness to life," he said.

"Those who scorn fundamental human ties and fail to learn how to bear even their limitations and fragility," he said, "more easily become intolerant and incapable of interacting with our complex world."

Pope Leo asked the people of Turkey to value their diversity, both cultural and religious. And he assured them that the nation's Catholic community -- about 35,000 people or less than 1% of the population -- wants to contribute.

"Uniformity would be an impoverishment," the pope said. "Indeed, a society is alive if it has a plurality, for what makes it a civil society are the bridges that link its people together."

Unfortunately, he said, today "communities are increasingly polarized and torn apart by extreme positions that fragment them."
