The Byzantine Liturgy is the product of a complex evolution that began before the time of Christ. Like its Western counterpart, the eucharistic service of the Eastern Orthodox churches consists of two parts. The first, the Liturgy of the Word, developed from the services of the Jewish synagogue. The second, the Liturgy of the Faithful, evolved from the prayer of blessing or brakah of the Passover and other Jewish religious meals.
The Coptic and Ethiopian liturgies are textually similar but quite different in style and setting. The Coptic liturgy is sober and restrained, while the Ethiopian liturgy is full of life and exuberance.
The liturgy of the Armenian church reveals the influence of many sources but is basically of Syrian origin. It expresses the theme of sacrifice more than other Eastern liturgies and has the flavor of a temple rite.
