From August 29-September 2, 2015, at the invitation of His All-Holiness Ecumenical Patriarch Bartholomew, a Synaxis of Hierarchs of the Ecumenical Throne gathered from all over the world at the Church of the Holy Trinity in Taksim Square. His All-Holiness delivered the Keynote Address to over 140 Hierarchs of the Throne, speaking to developments and challenges of the Ecumenical Patriarchate and the Orthodox Church in general during recent years. On September 1, 2015, the beginning of the ecclesiastical year, His All-Holiness presided over the Divine Liturgy, together with the Hierarchs in attendance. There followed the traditional Act of the Signing of the New Indiction.
