During the late Crusader period the Roman Catholic Church and the Armenian Apostolic Church attempted to establish an ecclesiastical union, under the auspices of similar doctrines and as a means of political alliance with the Latin held crusader states.This attempt at union was short-lived and merited little in terms of ecumenical dialogue. In 1341, Pope Benedict XII issues this document, serving as a polemic against members of the Armenian Church which did not see eye-to-eye with Rome in terms of doctrine and ecclesiology.
