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.
Protestants commonly use the term Lord’s Supper for the act of worship that centers on the table of the Lord. The Lord’s Supper originated with Jesus’ last supper with his disciples, in the context of the Passover, and shares with the Passover the theme of the Lord’s deliverance of Israel. As interpreted in the Gospels and by Paul, the Lord’s Supper is symbolic of Christ’s death, a memorial that places the worshiper at the Cross. It is the ratification of the covenant between the Lord and the people of God, an emblem of the communion or mutual participation of all members of the body of Christ. The Supper is a proclamation of the gospel and a symbol of faith in Christ.
