1 Corinthians 11:17-19

Verse 17

Now in this - I praise you not - In the beginning of this epistle the apostle did praise them for their attention in general to the rules he had laid down, see 1Cor 11:2; but here he is obliged to condemn certain irregularities which had crept in among them, particularly relative to the celebration of the Lord's Supper. Through some false teaching which they had received, in the absence of the apostle, they appear to have celebrated it precisely in the same way the Jews did their passover. That, we know, was a regular meal, only accompanied with certain peculiar circumstances and ceremonies: two of these ceremonies were, eating bread, solemnly broken, and drinking a cup of wine called the cup of blessing. Now, it is certain that our Lord has taken these two things, and made them expressive of the crucifixion of his body, and the shedding of his blood, as an atonement for the sins of mankind. The teachers which had crept into the Corinthian Church appear to have perverted the whole of this Divine institution; for the celebration of the Lord's Supper appears to have been made among them a part of an ordinary meal. The people came together, and it appears brought their provisions with them; some had much, others had less; some ate to excess, others had scarcely enough to suffice nature. One was hungry, and the other was drunken, μεθυει, was filled to the full; this is the sense of the word in many places of Scripture. At the conclusion of this irregular meal they appear to have done something in reference to our Lord's institution, but more resembling the Jewish passover. These irregularities, connected with so many indecencies, the apostle reproves; for, instead of being benefited by the Divine ordinance, they were injured; they came together not for the better, but for the worse.
Verse 18

There be divisions among you - They had σχισματα, schisms, among them: the old parties were kept up, even in the place where they assembled to eat the Lord's Supper. The Paulians, the Kephites, and the Apollonians, continued to be distinct parties; and ate their meals separately, even in the same house.
Verse 19

There must be also heresies - Αἱρεσεις· Not a common consent of the members of the Church, either in the doctrines of the Gospel, or in the ceremonies of the Christian religion. Their difference in religious opinion led to a difference in their religious practice, and thus the Church of God, that should have been one body, was split into sects and parties. The divisions and the heresies sprung out of each other. I have spoken largely on the word heresy in Act 5:17 (note), to which place I beg leave to refer the reader.
