“Ordained in the sacrament of baptism by water and the Spirit to be king and priest, the newly enlightened Christian is solemnly led into the Eucharistic assembly. ‘But we, after we have thus washed him who has been convinced and has assented to our teaching, bring him to the place where those who are called brethren are assembled, in order that we may offer hearty prayers in common for ourselves and for the baptized (illuminated) person, and for all others in every place. . . .
Having ended the prayers, we salute one another with a kiss. There is then brought to the president of the brethren bread and a cup of wine mixed with water; and he taking them, gives praise and glory to the Father of the universe, through the name of the Son and of the Holy Ghost, and offers thanks at considerable length for our being counted worthy to receive these things at His hands. And when he has concluded the prayers and thanksgivings, all the people present express their assent by saying Amen. . . .
And when the president has given thanks, and all the people have expressed their assent, those who are called by us deacons give to each those present to partake of the bread and wine mixed with water over which the thanksgiving was pronounced, and to those who are absent they carry away a portion.’”
(St. Justin the Martyr – d. 165AD – in The Church of the Holy Spirit by Nicholas Afanasiev, pg. 33)
