And so, on the eve of Good Friday (on which day this blog turns one year old), we come to the institution of the Lord’s Supper, and the Corinthian failure to understand it:
20 So then, when you come together, it is not the Lord’s Supper you eat, 21 for when you are eating, some of you go ahead with your own private suppers. As a result, one person remains hungry and another gets drunk. 22 Don’t you have homes to eat and drink in? Or do you despise the church of God by humiliating those who have nothing? What shall I say to you? Shall I praise you? Certainly not in this matter!
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.
How, in Paul’s view, were the Corinthians failing to participate in the Lord’s Supper? In a way parallel to every other issue in chs.8-14 of 1 Corinthians: They were exercising Christian knowledge/freedom/rights/experiences in a spirit of autonomous rivalry rather than in a spirit of love… they were failing to see that participation in Christ means participation in Christ’s body, the church.
The image of the “body” for a mutually contributing group was not new with Paul – it was used by others, especially as an image of a properly functioning city. Plato, you’ll recall, parallels a properly functioning person with a properly functioning city, in which each member plays its appropriate role. Maximus of Tyre, just after the time of Paul, writes:
Oration 15.4-5: But a city is something brought together by the joint work [sunergatōn] of all. The use of the body [sōmatos] is similar, which itself has many parts [polumerēs] and many requirements [poludeēs], and is preserved [sōzetai] by the joint aim of the parts [merōn] toward the corporation of the whole: Feet carry, hands work, eyes see, ears hear, and so on, lest I speak pedantically. But if the Phrygian story-maker wanted to compose a myth in which the foot, being fed up with the rest of the body [sōmati], gave up, due to weariness, carrying and lifting such a heavy load, and pursued leisure and rest; or if the molars, because of grinding and producing food for such a crowd, grew angry, and, being asked, refused to give attention to their proper work – if these things happened at once, what other than the destruction of the person would ensue in the myth? This sort of thing is indeed what happens with regard to the political fellowship [tēn koinōnian tēn politikēn]!
But for Paul, the idea of the “body” is not simply a useful analogy; it’s central to his understanding of what a Christian is – a believer belongs to Christ, and so shares in his body – thus one can’t share in the bread which is his body, while concurrently…
…Cursing other members of the body in the name of Jesus, following the pattern of contemporary curse tablets – many of which have been found in Ancient Corinth:
3 Therefore I want you to know that no one who is speaking by the Spirit of God says, “Jesus curse,” and no one can say, “Jesus is Lord,” except by the Holy Spirit.

…or placing one’s “spirituality” on display, imitating the individualistic, provocative, and status-based expressions of prayer/ritual/mystical expression common to the surrounding areas:
2 For those who speak in a tongue do not speak to other people but to God. Indeed, no one understands them; they utter mysteries by the Spirit. 3 But those who prophesy speak to people for their strengthening, encouragement and comfort. 4 Those who speak in a tongue edify themselves, but those who prophesy edify the church.
