1 Corinthians 11:20-30 (King James Version)

 ²⁰When ye come together therefore into one place, this is not to eat the Lord's supper.

 ²¹For in eating every one taketh before other his own supper: and one is hungry, and another is drunken.

 ²²What? have ye not houses to eat and to drink in? or despise ye the church of God, and shame them that have not? what shall I say to you? shall I praise you in this? I praise you not.

 ²³For I have received of the Lord that which also I delivered unto you, that the Lord Jesus the same night in which he was betrayed took bread:

 ²⁴And when he had given thanks, he brake it, and said, Take, eat: this is my body, which is broken for you: this do in remembrance of me.

 ²⁵After the same manner also he took the cup, when he had supped, saying, this cup is the new testament in my blood: this do ye, as oft as ye drink it, in remembrance of me.

 ²⁶For as often as ye eat this bread, and drink this cup, ye do shew the Lord's death till he come.

 ²⁷Wherefore whosoever shall eat this bread, and drink this cup of the Lord, unworthily, shall be guilty of the body and blood of the Lord.

 ²⁸But let a man examine himself, and so let him eat of that bread, and drink of that cup.

 ²⁹For he that eateth and drinketh unworthily, eateth and drinketh damnation to himself, not discerning the Lord's body.

 ³⁰For this cause many are weak and sickly among you, and many sleep.
