On Sunday, 3 March 2013, Archbishop Avak Assadourian and Bishop Ashod Menatsakanian from the Holy See of Etchmiadzin and Archbishops Gorun Babian and Nareg Alemezian from the Holy See of Cilicia represented the Armenian Orthodox Church at the enthronement of His Holiness Patriarch Abuna Mathias in Addis Ababa.

During the ceremony, Archbishop Gorun read the message of His Holiness Aram I, who described the long historical relationship between the two sister churches and particularly the recent close relations with the late Patriarch Abuna Paulos. The Catholicos said that he looked forward to working in that same spirit with the new patriarch.

The visit to Addis Ababa was also an opportunity for the Armenian delegation to celebrate the Holy Liturgy at the St. Gregory Armenian Church and to greet the community.
