The Armenian Rite (Armenian: Հայկական պատարագ)[1][2] is a liturgical rite used by both the Armenian Apostolic and the Armenian Catholic churches. Isaac of Armenia, the Catholicos of All Armenians, initiated a series of reforms with help from Mesrop Mashtots in the 5th century that distinguished Armenia from its Greek and Syriac counterparts. These reforms included a retranslation of the Bible and a revised liturgy. During the Crusades and afterwards, missionary activity by the Latin Church influenced liturgical norms and induced some Armenians to join the Catholic Church. The modern Armenian Rite features elements and interpolations from the Byzantine Rite and Latin liturgical rites, with the celebration of the Eucharist emulating the Liturgy of Saint Basil.
