亞美尼亞禮
The church belongs to the group of Eastern Rite Catholic churches and uses the Armenian Rite and the Armenian language in its liturgy. The Armenian Rite is also used by both the Armenian Apostolic Church and by a significant number of Eastern Catholic Christians in the Republic of Georgia. It is patterned after the directives of Saint Gregory the Illuminator, founder and patron saint of the Armenian Church. Unlike the Byzantine Church, churches of the Armenian rite are usually devoid of icons and have a curtain concealing the priest and the altar from the people during parts of the liturgy. The use of bishop's mitre and of unleavened bread is reminiscent of the influence Western missionaries once had upon both the miaphysite Orthodox Armenians as well as upon the Armenian Rite Catholics.
