Jamieson, Fausset and Brown on 1 Corinthians 11:24

24. brake--The breaking of the bread involves its distribution and reproves the Corinthian mode at the love-feast, of "every one taking before other his own supper."

my body ... broken for you--"given" (Lu 22:19) for you (Greek, "in your behalf"), and "broken," so as to be distributed among you. The oldest manuscripts omit "broken," leaving it to be supplied from "brake." The two old versions, Memphitic and Thebaic, read from Luke, "given." The literal "body" could not have been meant; for Christ was still sensibly present among His disciples when He said, "This is My body." They could only have understood Him symbolically and analogically: As this bread is to your bodily health, so My body is to the spiritual health of the believing communicant. The words, "Take, eat," are not in the oldest manuscripts.

in remembrance of me--(See on 1Co 11:25).
