Orthodox Christian unity at all levels has long been the priority of the Antiochian Archdiocese, and Sayidna shares in this. He has built official relations with His Eminence, Metropolitan GERASIMOS (Michaleas) of the Greek Orthodox Christian Metropolis of San Francisco; His Grace, Bishop MAXIM (Vasilijevic) of the Serbian Orthodox Christian Diocese of Western America; and His Grace, Bishop BENJAMIN (Peterson) of the Orthodox Church in America’s Diocese of the West. From their first gathering on Bright Tuesday, 2007 to their newly-established tradition of concelebrating the Hierarchical Divine Liturgy on the Sunday of Orthodoxy, Sayidna has stressed the importance of expressing our Holy Orthodox Faith with one voice, not just administratively, but through the liturgy and the sacraments. The hierarchs hosted the first-ever inter-Orthodox clergy retreat during the 2009 Advent Season, allowing many priests and deacons to meet each other for the first time.
