The Revelation to John makes dramatic use of the rich symbolism of the sacrificial ritual of the Jewish temple. A comparison of the language and imagery of the book of Revelation with the Divine Liturgy of the Orthodox churches suggests that in the Revelation we see an early stage in the development of Christian liturgy, especially that of the Eastern churches.
Several traditional acts of worship accompany the receiving of the Lord’s Supper. Some form of “fraction,” or breaking of the bread, is found in most observances of the rite. In addition, the distribution of the Eucharist may incorporate the Agnus Dei (“Lamb of God”), the acclamation “Christ Our Passover,” and a concluding prayer of thanksgiving.
