703. The Institution of the Supper by the Lord:
Jesus kept the passover with His disciples; and when evening had come He sat down with them. And as they were eating, Jesus took bread and blessed, and brake, and gave to His disciples, and said, Take, eat, this is My body. And He took the cup and gave thanks, and gave to them, saying, Drink of it, all of you; this is My blood of the new covenant, which is poured out for many (Matt. 26:26-28; Mark 14:22-24; Luke 22:19-20).
The Lord's Doctrine respecting His Flesh and Blood, and the Bread and Wine:
Work not for the meat that perisheth, but for that meat which abideth unto eternal life, which the Son of man shall give unto you. Verily, verily, I say unto you, it was not Moses that gave you the bread out of heaven, but My Father giveth you the true bread out of heaven; for the bread of God is He that cometh down out of heaven, and giveth life unto the world. I am the bread of life; he that cometh to Me shall not hunger, and he that believeth in Me shall never thirst. I am the bread which came down out of heaven. Verily, verily, I say unto you, He that believeth in Me hath eternal life. I am the bread of life. Your fathers did eat manna in the wilderness and they died. This is the bread which cometh down out of heaven, that one may eat thereof and not die. I am the living bread which came down from heaven; if any man eat of this bread he shall live forever; and the bread that I will give is My flesh, which I will give for the life of the world. Verily, verily, I say unto you, Except ye eat the flesh of the Son of man, and drink His blood, ye have no life in you. He that eateth My flesh and drinketh My blood hath eternal life, and I will raise him up at the last day; for My flesh is truly meat, and My blood is truly drink. He that eateth My flesh and drinketh My blood abideth in Me and I in him (John 6:27-56).
