The city of Iznik, ancient Nicaea, marked a key stop on Pope Leo XIV’s visit to Turkey, as the pontiff led a service dedicated to Christian unity on the shores of Lake Iznik, south of Istanbul. The ceremony brought together Orthodox and Protestant leaders for a prayer service among the ruins of a submerged 4th-century basilica. The Mass commemorated the 1,700th anniversary of the First Ecumenical Council of Nicaea, convened in 325, twelve years after the Roman Empire legalized Christianity. Standing beside Patriarch Bartholomew I of Constantinople and other church leaders, Pope Leo XIV recited the Nicene Creed — a statement of faith still recited by millions of Christians worldwide. The creed was first adopted at the very council that gathered in Nicaea almost 17 centuries ago.
