On the Feast of the Apostle Saint Andrew, founder of the See of Constantinople, Pope Leo XIV participated in the Divine Liturgy presided over by Ecumenical Patriarch Bartholomew I at the Patriarchal Church of St. George in Istanbul. Gathered with bishops, clergy, religious, and representatives of various Christian Churches, the Pope prayed for unity during his Apostolic Journey marking the 1,700th anniversary of the First Council of Nicaea. In his address, Pope Leo XIV recalled the essential witness of the Ecumenical Councils, the historic meeting of Paul VI and Athenagoras in 1964, and reaffirmed the Catholic Church’s commitment to full communion with the Orthodox Church. He called all Christians to deepen spiritual conversion, collaborate for peace, respond to global challenges, and safeguard creation together. The celebration concluded with Pope Leo XIV and Patriarch Bartholomew I imparting an ecumenical blessing from the church balcony — a powerful sign of hope for unity. #PopeLeoXIV #PapaLeaoXIV #PapaLeoneXIV #PatriarchBartholomew #EcumenicalPatriarchate #FeastOfStAndrew #StAndrew #DivineLiturgy #Istanbul #Constantinople #Catholic #Orthodox #ChristianUnity #Ecumenism #Nicaea1700 #ApostolicJourney #Vatican #VaticanNews #ChurchHistory #Christianity #Peace #Faith #Turkey #FYP #ForYou #PopeLeoXIV #VaticanBlessing #FaithMoment #CatholicChurch #Blessing #VaticanCity #SpiritualJourney #FamilyFaith #HolyMoment #ChristianYouTube
