Shared ground
Paul is not introducing a new ritual. He reminds the Corinthians of a tradition he says he received and then passed on to them (1 Corinthians 11:23). He places it in a specific moment: the night Jesus was betrayed/handed over. The actions are concrete and repeated: bread is taken, thanks is given, it is broken, and words are spoken over it; then a cup is taken after the meal and words are spoken over it.
The tradition ties the meal to Jesus’ death. The bread is identified with Jesus’ body “for you,” and the cup is tied to “the new covenant in my blood.” The repeated eating and drinking has a public meaning: it “proclaims the Lord’s death” and it looks ahead to an endpoint “until he comes” (1 Corinthians 11:26).
Where interpretation differs
“I received from the Lord” (v. 23). Some read this as Paul saying he got these words directly from Jesus (for example, by revelation). Others read it as Paul emphasizing the Lord as the ultimate source of an already-circulating tradition he learned from other believers.
“This is my body” (v. 24). Some take the wording as a strong identification between the bread and Jesus’ body that goes beyond a purely illustrative comparison. Others read it as ordinary meal-language where an item stands for what it represents, with the main point being remembrance and proclamation.
“Proclaim the Lord’s death” (v. 26). Some understand the proclamation mainly as what the act itself communicates when done as a community ritual. Others think proclamation also includes spoken explanation alongside the eating and drinking.
Why the disagreement exists
The passage reports short, remembered sayings used in a communal meal. Such sayings can carry layered meaning: “is” can function as identification or representation; “received from the Lord” can describe direct instruction or authoritative tradition; and “proclaim” can describe a message conveyed by actions, by words, or by both. Paul does not pause here to clarify those details because his immediate purpose is to restate the core tradition as the standard for their gatherings.
What this passage clearly contributes
This text anchors the Lord’s Supper in Jesus’ last-night actions and words, and it frames the practice as repeatable (“do this … as often as”). It explicitly links the bread to Jesus’ body “for you,” and the cup to “the new covenant in my blood.” It also explains the meal’s ongoing meaning: each repetition publicly announces Jesus’ death and points forward to his coming. Those claims supply the theological “center” Paul uses in the surrounding context to critique the Corinthians’ behavior at the table.
