Some food for thought: “One form with six generally accepted parts pattern of the ancient Near Eastern treaties. They are: (1) preamble, or introduction of the speaker, (2) historical prologue, (3) stipulations, (4) the document, (5) the gods as witnesses, and (6) curses and blessings.” Rene Lopez, CTS Journal.
(1) For I received from the Lord what I also delivered to you, that (2) the Lord Jesus on the night when he was betrayed took bread, and when he had given thanks, he broke it, and said, (3) “This is my body which is for you. Do this in remembrance of me.” In the same way also he took 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.” (5) For as often as you eat this bread and drink the cup, you proclaim the Lord’s death until he comes. (6) Whoever, therefore, eats the bread or drinks the cup of the Lord in an unworthy manner will be guilty concerning the body and blood of the Lord. Let a person examine himself, then, and so eat of the bread and drink of the cup. For anyone who eats and drinks without discerning the body eats and drinks judgment on himself. That is why many of you are weak and ill, and some have died. But if we judged ourselves truly, we would not be judged. But when we are judged by the Lord, we are disciplined so that we may not be condemned along with the world. So then, my brothers, when you come together to eat, wait for one another— if anyone is hungry, let him eat at home—so that when you come together it will not be for judgment. About the other things I will give directions when I come. (1 Corinthians 11:23-34 ESV)
This is covenant renewal for the Christian.
