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."
 

Istanbul, Turkey, Nov 28, 2025 / 03:00 am (CNA).

Pope Leo XIV visited the Nursing Home of the Little Sisters of the Poor in Istanbul on Friday, telling the community that Christian charity begins not with doing but with being — i.e., living a real communion with those one serves.

“The secret of Christian charity is that before being for others, we must first be with others in a communion based on fraternity,” he said during the encounter on Nov. 28, the second day of his apostolic trip to Turkey, where he is marking the 1,700th anniversary of the First Council of Nicaea.

A papal stop at a charitable institution has become customary during international journeys, and Pope Leo chose to spend time with the elderly as a sign of closeness to those often marginalized in modern societies.

Founded in France in 1839 by St. Jeanne Jugan, the Little Sisters of the Poor serve elderly people in need around the world, including in Turkey, where they welcome residents of different religious backgrounds. The pope was greeted at the residence by the mother superior, former superior, and provincial leader before proceeding to the chapel to meet residents, staff, and benefactors.

Reflecting on the congregation’s name, the pope told the sisters that their mission mirrors the life of Christ himself. “The Lord has called you not only to assist or help the poor but has also called you to be their ‘sisters.’ You are to be like Jesus, whom the Father sent to us not only to help and serve us but also to be our brother.”

Turning to the residents, he warned that the word “elderly” risks losing its meaning in cultures driven by efficiency and materialism. Such attitudes, he said, lead societies to forget the dignity and value of older persons. Scripture and tradition, by contrast, present the elderly as bearers of memory and wisdom.

“As Pope Francis loved to repeat — the elderly are the wisdom of a people, a treasure for their grandchildren, families, and society as a whole,” he said.

Pope Leo concluded by thanking the community for its patient, prayerful witness and prayed that the Lord would strengthen all who live and serve in the home.

Istanbul, Turkey, Nov 28, 2025 / 01:55 am (CNA).

Pope Leo XIV encouraged Turkey’s small Catholic community Friday to rediscover what he called the Gospel’s “logic of littleness,” urging them not to be discouraged by their tiny numbers but to recognize in them the strength of authentic Christian witness.

The pope addressed bishops, priests, religious, pastoral workers, and laypeople at the Cathedral of the Holy Spirit in Istanbul on his second day in the country. Catholics in Turkey make up roughly 0.05% of the nation’s 85 million people.

Calling Turkey a “holy land” where the Old and New Testaments meet, the pope recalled the deep Christian roots of the region: Abraham’s journey through Harran, the early Christian communities in Antioch and Ephesus, and the long and influential history of Byzantine Christianity. He noted in particular that the Ecumenical Patriarchate of Constantinople, currently led by Patriarch Bartholomew I, remains “a point of reference” both for its Greek faithful and for other Orthodox churches.

The pope warned Christians not to treat this heritage merely as a memory of past greatness. Instead, he urged them to adopt “an evangelical vision” that sees their present reality through the Holy Spirit’s light.

“When we look with God’s eyes, we discover that he has chosen the way of littleness,” he said, pointing to the mustard seed, the little ones praised by Jesus, and the quiet growth of the kingdom of God. The Church’s true strength, he explained, “does not lie in her resources or structures,” nor in numbers or influence, but in remaining gathered around Christ and sent by the Holy Spirit.

Quoting Jesus’ words “Do not be afraid, little flock,” the pope encouraged Christians in Turkey to cultivate hope. He pointed to the growing number of young people approaching the Catholic Church as a sign of promise and asked communities to continue welcoming and accompanying them.

He urged particular dedication to ecumenical and interreligious dialogue, the transmission of the faith to local communities, and pastoral service to refugees and migrants — many of whom are among the most vulnerable people in the country. The pope also noted that many Catholics in Turkey come from abroad, a reality that calls for a deeper process of inculturation so that the language and culture of the country become “more and more your own.”

The pope highlighted Turkey’s unique role in the history of the Church, recalling that the first eight ecumenical councils were held on its soil. Marking the 1,700th anniversary of the First Council of Nicaea, he said the council continues to pose three questions to Christians today: What is the essence of the faith? Who is Jesus for us? And how should doctrine be expressed in ways that speak to contemporary culture?

He warned against what he described as a “new Arianism,” a version of the heresy that divided Christianity in its early centuries, that reduces Jesus to a moral teacher or heroic figure while denying his divinity and lordship over history.

Before concluding, the pope invoked the memory of St. John XXIII, who served in Turkey and wrote affectionately of its people. Reflecting on the saint’s image of Bosporus fishermen laboring through the night, he encouraged Turkish Catholics to persevere in the same spirit: working faithfully, joyfully, and courageously “in the Lord’s boat.”

The Cathedral of the Holy Spirit, where the meeting took place, was built in 1846 and houses relics of early popes, including St. Linus. A statue of Pope Benedict XV stands in its courtyard, erected in gratitude for his efforts to help victims of the 1915–1918 war. The inscription honors him as a “benefactor of peoples, without distinction of nationality or religion.”
