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.
The churches in the Byzantine tradition are those with an historic relationship to the church of Constantinople (originally Byzantium); they are familiar to North Americans as the Orthodox churches (among them the Greek and Russian). The Byzantine rite is complex and proceeds as two interwoven liturgies, one conducted with the congregation and the other performed by the celebrants behind the icon screen (iconostasis) that separates the altar from the rest of the church. The dominant theme of this liturgical tradition is the presence of Christ, both in his incarnation and in his heavenly ministry.
