[/FONT]The Early Church looked upon the Eucharist as a
re-presentation, which they were instructed to do, of the one sacrifice. Here are some excerpts from scripture, followed by some from a couple ECFs, followed by one from the Didache, an early catechism:
"The cup of blessing which we bless, is it not a participation in the blood of Christ? The bread which we break, is it not a participation in the body of Christ? Because there is one bread, we who are many are one body, for we all partake of the one bread."
"For I received from the Lord what I also delivered to you, that the Lord Jesus on the night when he was betrayed took bread, and when he had given thanks, he broke it, and said, 'This is my body which is for you. Do this in remembrance of me.' In the same way also the cup, after supper, saying, 'This cup is the new covenant in my blood. Do this, as often as you drink it, in remembrance of me.' For as often as you eat this bread and drink the cup, you proclaim the Lord's death until he comes. Whoever, therefore, eats the bread or drinks the cup of the Lord in an unworthy manner will be guilty of profaning the body and blood of the Lord."
"Since then these things are manifest to us, and we have looked into the depths of the divine knowledge, we ought to do in order all things which the Master commanded us to perform at appointed times. He commanded us to celebrate sacrifices and services, and that it should not be thoughtlessly or disorderly, but at fixed times and hours. He has Himself fixed by His supreme will the places and persons whom He desires for these celebrations, in order that all things may be done piously according to His good pleasure, and be acceptable to His will. So then those who offer their oblations at the appointed seasons are acceptable and blessed, but they follow the laws of the Master and do not sin. For to the high priest his proper ministrations are allotted, and to the priests the proper place has been appointed, and on Levites their proper services have been imposed. The layman is bound by the ordinances for the laity."
St. Clement of Rome, 80 A.D., to the Corinthians
[Christ] has declared the cup, a part of creation, to be his own Blood, from which he causes our blood to flow; and the bread, a part of creation, he has established as his own Body, from which he gives increase to our bodies."
St. Irenaeus of Lyons, Against Heresies, 180 A.D.
"So then, if the mixed cup and the manufactured bread receive the Word of God and become the Eucharist, that is to say, the Blood and Body of Christ, which fortify and build up the substance of our flesh, how can these people claim that the flesh is incapable of receiving God's gift of eternal life, when it is nourished by Christ's Blood and Body and is His member? As the blessed apostle says in his letter to the Ephesians, 'For we are members of His Body, of His flesh and of His bones' (Eph. 5:30). He is not talking about some kind of 'spiritual' and 'invisible' man, 'for a spirit does not have flesh an bones' (Lk. 24:39). No, he is talking of the organism possessed by a real human being, composed of flesh and nerves and bones. It is this which is nourished by the cup which is His Blood, and is fortified by the bread which is His Body. The stem of the vine takes root in the earth and eventually bears fruit, and 'the grain of wheat falls into the earth' (Jn. 12:24), dissolves, rises again, multiplied by the all-containing Spirit of God, and finally after skilled processing, is put to human use. These two then receive the Word of God and become the Eucharist, which is the Body and Blood of Christ."
St. Irenaeus of Lyons, Unmasking and Refutation of the Falsely named Gnosis 180AD
"On the Lord's own day, assemble in common to break bread and offer thanks; but first confess your sins, so that your sacrifice may be pure. However, no one quarreling with his brother may join your meeting until they are reconciled; your sacrifice must not be defiled. For here we have the saying of the Lord: 'In every place and time offer me a pure sacrifice; for I am a mighty King, says the Lord; and my name spreads terror among the nations.'"
The Didache Ch14 2nd Century
