Ignatius A.D. 30 - 107 disciple of the apostles
Take ye heed, then, to have but one Eucharist. For there is one flesh of our Lord Jesus Christ, and one cup to show forth the unity of His blood; one altar; as there is one bishop, along with the presbytery and deacons, my fellow-servants: that so, whatsoever ye do, ye may do it according to the will of God.
Irenaeus A.D. 120-202 Bishop of Lyon student of Polycarp St.John
Again, giving directions to His disciples to offer to God the first-fruits of His own, created things—not as if He stood in need of them, but that they might be themselves neither unfruitful nor ungrateful—He took that created thing, bread, and gave thanks, and said, “This is My body. And the cup likewise, which is part of that creation to which we belong, He confessed to be His blood, and taught the new oblation of the new covenant; which the Church receiving from the apostles, offers to God throughout all the world, to Him who gives us as the means of subsistence the first-fruits of His own gifts in the New Testament, concerning which Malachi, among the twelve prophets, thus spoke beforehand: “I have no pleasure in you, saith the LORD Omnipotent, and I will not accept sacrifice at your hands. For from the rising of the sun, unto the going down [of the same], My name is glorified among the Gentiles, and in every place incense is offered to My name, and a pure sacrifice; for great is My name among the Gentiles, saith the LORD Omnipotent; indicating in the plainest manner, by these words, that the former people [the Jews] shall indeed cease to make offerings to God, but that in every place sacrifice shall be offered to Him, and that a pure one; and His name is glorified among the Gentiles.
Justin Martyr
And this food is called among us Εὐχαριστία thanksgiving. [the Eucharist], of which no one is allowed to partake but the man who believes that the things which we teach are true, and who has been washed with the washing that is for the remission of sins, and unto regeneration, and who is so living as Christ has enjoined. For not as common bread and common drink do we receive these; but in like manner as Jesus Christ our Saviour, having been made flesh by the Word of God, had both flesh and blood for our salvation, so likewise have we been taught that the food which is blessed by the prayer of His word, and from which our blood and flesh by transmutation are nourished, is the flesh and blood of that Jesus who was made flesh. For the apostles, in the memoirs composed by them, which are called Gospels, have thus delivered unto us what was enjoined upon them; that Jesus took bread, and when He had given thanks, said, “This do ye in remembrance of Me, this is My body;” and that, after the same manner, having taken the cup and given thanks, He said, “This is My blood;” and gave it to them alone. Which the wicked devils have imitated in the mysteries of Mithras, commanding the same thing to be done. For, that bread and a cup of water are placed with certain incantations in the mystic rites of one who is being initiated, you either know or can learn.
Early liturgy practiced by the apostles and early Christians can be read in from a parchment which is extant and written by It was written not earlier than the death of James, Apostle and Martyr, A.D. 42, and probably not later than A.D. 67; when Dionysius, at the request of St. Paul, left Athens to meet the Apostle at Rome, for the purpose of being sent by him to Gaul.
…I crave Thy holy Spirit, that Thou wouldst send Him upon me, and upon these oblations, here set forth, and upon Thy faithful people.” Pr. “Hear me, O Lord.” P. “Kyrie eleison,” three times. Pr. “Through His alighting upon them, and His overshadowing, may He make this bread indeed, living body, and procuring life to our souls; body salutary—body celestial—body saving our souls and bodies—body of our Lord God and Saviour, Jesus Christ—for remission of sins, and eternal life, for those receiving it.” P. “Amen.” Pr. “And the commixture, which is in this cup, may He make living blood, and procuring life to all our souls; blood salutary—blood celestial—blood saving our souls and bodies—blood of our Lord God and Saviour Jesus Christ, for remission of sins to those receiving them.” P. “Amen.” Pr. “Further, according to the tradition, and Divine recommendation of those, who were eye witnesses of Thy mysteries, and interpreters of Thy wonderful acts, we offer this Eucharist before Thee, O Lord, and through it we commemorate Thy charity towards us, and the universal dispensation of Thine Only-begotten One, in this world, that Thou wouldst also be reminded through it of Thy mercy, cognate and natural to Thee, which, at all hours, is shed upon Thy creatures, and wouldst snatch us from the wrath, reserved for the wicked; and from the punishments of those who work iniquity; and from the cruel attack of demons, who attack our souls, when we shall go hence; and wouldst make us worthy of Thy kingdom, and the habitations of those who have kept Thy precepts;
and we will render to Thee, glory and the giving of thanks,
“Amen.” …
