Explanation of the Faith of the Armenian Church

In the year 1166, the Eastern Roman Emperor Manuel I made a request of the head of the Armenian church to compose a short explanation to the history and constitution of their church structure, so that it might remain independent from the Imperial church in Asia Minor. The result of that request is this document, composed by the the contemporary Catholicos of All Armenian, Nerses IV, who explained the unique features of Armenian liturgy and ecclesiology, and how it differed from the more familiar Greek and Latin traditions.
