In 1 Corinthians 11, Paul discusses "the Lord's Supper" (v. 20). He said that when Jesus was betrayed, He took the bread (vv. 23-24), and then, "after supper," He took the cup (v. 25, NKJV). I don't think Paul is implying that the cup was after "the Lord's Supper," as I've always understood both the bread and fruit of the vine as constituting "the Lord's Supper." However, it is interesting to see the drinking of the cup described as taking place "after supper" (v. 25, NKJV).
Assuming the cup is part of the Lord's Supper, why does Paul describe the taking of the cup as being "after supper"?
1 Cor 11:25 - In the same way, after supper He took the cup, saying, “This cup is the new covenant in My blood; do this, as often as you drink it, in remembrance of Me.”
