Pope Leo XIV said he hopes to travel to Türkiye later this year to mark the 1,700th anniversary of the First Council of Nicaea, the landmark 325 AD gathering that produced the Nicene Creed. Addressing Greek Orthodox, Byzantine Catholic and Latin Catholic pilgrims at his summer residence in Castel Gandolfo on Thursday, the pontiff expressed a desire to participate in an ecumenical commemoration in İznik, the ancient city of Nicaea. If confirmed, the journey would be the first foreign trip of Leo’s papacy. Turkish officials said the Pope relayed the plan to First Lady Emine Erdoğan during a Vatican audience earlier this month, and church sources have cited 30 November—Saint Andrew’s Day and an important feast for the Eastern Orthodox Church—as a provisional date. Ecumenical Patriarch Bartholomew, who leads the world’s Orthodox Christians, is expected to attend the commemoration. Leo, elected on 8 May following the death of Pope Francis, inherits his predecessor’s goal of highlighting common Christian roots with the Orthodox world. A visit to Türkiye would underscore that agenda while coinciding with the anniversary of a council that shaped core Christian doctrine.
