1 Corinthians 11:23-29

That is what the Lord Jesus meant by his words at that last supper the night on which they took him, when he handed the cup to his disciples, and broke the bread for them. I taught you his words and his action on that occasion, as they were given me by those who were present. After taking the bread, he gave thanks, spoke the usual blessing, and handed it to them, saying, “This is my body, which is surrendered on your behalf. In future, when you break bread thus, and give thanks, remember my body, remember me.” In handing the cup after dinner, he said, “This is the new covenant, sealed in my blood. In future, whenever you take wine thus together, think of this new covenant, remember my blood.” Do you then my brethren, when you come together, eating and drinking, with the intention of carrying out his injunction, and recalling his words, do you really discern beneath this semblance and type of bread and wine the eternal body of Christ to which we belong? Do you really celebrate that wondrous death of his, which differed from all other deaths in that it is to be followed by his second coming and eternal presence in the world? Examine yourselves on these points, and assemble together in that spirit only. Otherwise you will only eat and drink the doom of all flesh, as it comes upon the whole world. But if you discerned that infinite eternal body, if you understood the meaning of Christ’s death in the flesh, and what is signified by the shedding of his blood, and the giving up of his mortal life and material body
