Pope Leo XIV, at Mass in Turkey, calls for Catholic, ecumenical and interreligious unity

Istanbul, Turkey, Nov 29, 2025 / 11:20 am

Pope Leo XIV marked the start of Advent on Saturday with an appeal for unity and peace, telling thousands gathered for Mass in Istanbul that Christians “journey as if on a bridge that connects earth to Heaven,” keeping their eyes “fixed on both shores” until they are united “in the house of the Father.”

The pope celebrated Mass on Nov. 29 at the Volkswagen Arena, a large multipurpose venue within Istanbul’s Uniq cultural complex. The liturgy, held on the eve of the Feast of St. Andrew, patron of Turkey, took place during the third day of his first international apostolic trip, which has brought him to Turkey and will soon continue on to Lebanon.

In his homily, the pope reflected on the beginning of Advent, saying it prepares believers “to experience anew at Christmas the mystery of Jesus, the Son of God, begotten, not made, consubstantial with the Father.” Drawing on the first reading from Isaiah (Is 2:1–5), he invited the faithful “to ascend the mountain of the Lord,” which he described as an image of divine light and peace.

Leo pointed to two key images in the reading. The first was the mountain “established as the highest of the mountains,” which he said reminds Christians that God’s gifts “are a gift not only for us, but for everyone.” He cited examples of evangelizing witness: St. Peter meeting Christ through St. Andrew’s enthusiasm, and St. Augustine coming to the faith through St. Ambrose. Recalling a line from St. John Chrysostom—“The miracle happens and passes, but the Christian life remains and continually edifies”—he urged the faithful to “keep watch” with prayer, charity, and spiritual vigilance.

The second image was the prophet’s vision of peace: “They shall beat their swords into plowshares… neither shall they learn war any more.” The pope said the message is especially urgent today, calling the Church to be a sign of reconciliation in a world marked by conflict.

Turning to the theme of bridges, Leo noted that the logo for his visit to Turkey features the Bosporus Bridge, which joins Asia and Europe. He said the image points to three essential “bridges of unity”: within the Catholic community, in relations with other Christians, and in dialogue with other religions.

The pope highlighted the four Catholic traditions present in Turkey—Latin, Armenian, Chaldean, and Syriac—calling them “a catholicity that unites.” Unity, he said, “needs care, attention, and maintenance.” Quoting Christ’s prayer “that they may all be one,” he appealed again for Christian unity and encouraged believers to be peacemakers.

The diversity of Turkey’s Catholic community was visible in the liturgy. A choir of about 200 members represented the country’s four rites. Scripture readings and prayer intentions were offered in Turkish, Aramaic, Syriac, English, Armenian, and Arabic, reflecting the multilingual and multicultural character of local Catholics.

On Sunday afternoon, the pope will depart Turkey for the second leg of his apostolic journey in Lebanon. Before leaving Istanbul, he is scheduled to participate in several ecumenical events in the morning.
