At the invitation of His All-Holiness Ecumenical Patriarch Bartholomew, the First-Hierarchs of all the Orthodox Autocephalous Churches have gathered from March 6-9, 2014, for a Sacred Synaxis at the Phanar in order to deliberate on matters pertaining to the entire Orthodox Church throughout the world and procedural issues for the convocation of the Holy and Great Council, whose preparation is coming to an end. The sessions began with prayer lead by His All holiness the Ecumenical Patriarch.
Prior to this, from March 4-5, 2014, a Preparatory Committee for the Synaxis was also held at the Ecumenical Patriarchate, chaired by His Eminence Metropolitan John of Pergamon, in order to formulate the program of proceedings and draft the Message of the First-Hierarchs, who will conclude the Synaxis with a concelebration on the Sunday of Orthodoxy in the venerable Patriarchal Church of St. George, thereby also visibly expressing the unity of Orthodoxy.
During this festive Divine Liturgy on the occasion of great feast of Orthodoxy, the Message of the First-Hierarchs will be read from the Patriarchal Ambon to the faithful of the Most Holy Churches throughout the world.
