An alternate Eucharist tradition is preserved in the Didache and is hinted at in the Valentinian Gnostic teachings.
Didache chapter 9 says this:
Now concerning the Eucharist, give thanks this way. First, concerning the cup:
We thank thee, our Father, for the holy vine of David Thy servant, which You madest known to us through Jesus Thy Servant; to Thee be the glory for ever.
And concerning the broken bread:
We thank Thee, our Father, for the life and knowledge which You madest known to us through Jesus Thy Servant; to Thee be the glory for ever. Even as this broken bread was scattered over the hills, and was gathered together and became one, so let Thy Church be gathered together from the ends of the earth into Thy kingdom; for Thine is the glory and the power through Jesus Christ for ever.
The Didache is an interesting text which has confounded scholars. Some date it earlier even than Paul's writings, circa 50 AD. Others place it after the Gospel of Matthew, and therefore circa 100 AD. It seems to me that there are sections with a clear dependence on Matthew, but these are delineated and were probably (IMO) redactions. Much of the text feels "independent" as it describes a form of Christianity free of the stylizations of Paul and the Gospels. It is hard to imagine a Christian tradition after Paul or the Gospels not drawing from them (though as I explain below there may have been some reason for this, in the case of the Eucharist) -- so the bulk of it most likely predates other Christian writings.
The Didache is the product of an "Ebionite" community -- one of several strains of early Christianity who held strongly to Jewish tradition and worldview. As
I have held before, the Gnostics grew largely out of the Jewish tradition and seem to have been allied with the Ebionites on this matter. For example, consider this:
We give thanks to you and we celebrate the eucharist, O Father, remembering for the sake of thy Son, Jesus Christ that they come forth [...] invisible [...] thy [Son....] his [love...] to [knowledge ......] they are doing thy will through the name of Jesus Christ and will do thy will now and always. They are complete in every spiritual gift and every purity. Glory be to thee through thy Son and they offspring Jesus Christ from now and forever. Amen.
This is from a fragment titled
"On the Eucharist A". It seems to me to have a couple of similarities to the Didache ritual, notably that the breaking of bread is done in
memory of Jesus but in
praise to the Father.
The
Gospel of Philip also contains a passage that seems to speak to this alternate Eucharist tradition:
The eucharist is Jesus. For he is called in Syriac "Pharisatha," which is "the one who is spread out," for Jesus came to crucify the world.
This brings to mind the description of the church as "gathered together from the ends of the earth into Thy kingdom," and reflects our understanding of the agape feast (the center of early Christian life) as fostering of community and togetherness. Bread, it was pointed out to me by
lady_babalon, requires an entire community to make and therefore represents the fruit of working together.
Likewise, the
"Prayer of Thanksgiving" focuses on the Father and gives no mention to Jesus or Christ at all.
"We give thanks to You! Every soul and heart is lifted up to You, undisturbed name, honored with the name 'God' and praised with the name 'Father', for to everyone and everything (comes) the fatherly kindness and affection and love, and any teaching there may be that is sweet and plain, giving us mind, speech, (and) knowledge: mind, so that we may understand You, speech, so that we may expound You, knowledge, so that we may know You. We rejoice, having been illuminated by Your knowledge. We rejoice because You have shown us Yourself. We rejoice because while we were in (the) body, You have made us divine through Your knowledge.
"The thanksgiving of the man who attains to You is one thing: that we know You. ..."
When they had said these things in the prayer, they embraced each other and they went to eat their holy food, which has no blood in it.
So how did it come to be about Jesus? The answer to that is Paul. It is interesting that the Valentinians, who otherwise drew heavily from Paul, did not use his Eucharist. This may be because the Pauline Eucharist ritual had already become a divisive issue for Gnostics and Ebionites. (John, interestingly, did not mention the Eucharist at all, but instead described a sacrament of foot-washing at the last supper. Could this be another piece of evidence that
John was the product of a Gnostic-leaning or "proto-Gnostic" community?)
As I have written before, Paul seems to have believed that the people of the church made up literally the body of the resurrected Christ -- the "pneumatic body," or "body made of spirit/breath/air," contrasted with the "psychic body," or "body made of flesh and bone." If Paul took the Church to be the resurrected body of Christ, then it might be thought of as a body made of bread and wine -- the elements of the agape feast where the church, made of people once scattered but now brought together, met and celebrated their unity. ("Where there are two or three gathered in my name, there I am" Matthew 18:20).
When Paul described the Eucharist in I Corinthians 11, it was in the context of it as a feast of sharing. In this passage, allowing a fellow Christian to go hungry during this feast was characterized as a sin against the "body and blood of Christ:"
[I Corinthians 11:20] When you come together, it is not the Lord's Supper you eat,
[21] for as you eat, each of you goes ahead without waiting for anybody else. One remains hungry, another gets drunk.
[22] Don't you have homes to eat and drink in? Or do you despise the church of God and humiliate those who have nothing? What shall I say to you? Shall I praise you for this? Certainly not!
[23] For I received from the Lord what I also passed on to you: The Lord Jesus, on the night he was betrayed, took bread,
[24] 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."
[25] In the same way, after supper he took the cup, saying, "This cup is the new covenant in my blood; do this, whenever you drink it, in remembrance of me."
[26] For whenever you eat this bread and drink this cup, you proclaim the Lord's death until he comes.
[27] Therefore, whoever eats the bread or drinks the cup of the Lord in an unworthy manner will be guilty of sinning against the body and blood of the Lord.
[28] A man ought to examine himself before he eats of the bread and drinks of the cup.
[29] For anyone who eats and drinks without recognizing the body of the Lord eats and drinks judgment on himself.
The gospels touch on this, because the betrayal of Judas is revealed at the last supper, after he has taken bread broken by Jesus. In fact, the Gospel of John tells that Satan entered Judas after he ate the bread given to him by Jesus. Thus Judas betrayed not just Jesus but the community as a whole.
