The MS is a copy of the abridged version of "The Shield of Faith, Concerning the Orthodoxy of the Armenian Church" (Vahan havatoy ułłap῾aṙut῾ean Hayastaneayc῾ Yekełec῾voy), authored by the Venice Mekhitarist Father Mik῾ayēl Č’amčian (1738-1823). According to Ormanian, the original unabridged manuscript of this work, a copy of which he saw in the library of the Antonian Armenian Catholic monastic order at Constantinople, consisted of 924 handwritten pages (see Ormanian, 1816, Azgapatum, para. 2165). In this work, which was written during the years 1776-1816, Č’amčian endeavored to defend the "orthodoxy" of the Armenian church against Catholic Armenian charges that it had deviated from the truth. There were ten such charges, namely, that the Armenians: 1) reject the decisions of the Council of Chalcedon; 2)proclaim only one nature in Christ; 3)reject the procession of the Holy Spirit from the Father and the Son; 4) hold an erroneous position toward life in the hereafter; 5) recite "Holy God" with the addition of "who were crucified for us"; 6) celebrate Christmas on January 6; 7)do not dilute the Eucharistic wine; 8) do not conform to the observance of the Roman church'es rules and commandments; 9) reject extreme unction; 10) reject the primacy of the Roman see. Discussing each of these accusations, Č’amčian concludes that the charges are groundless and that "there is no justification for calling the Armenians deviationists or heretics; rather, they must be recognized as orthodox".
