1 Corinthians 11:20-22

Verse 20

This is not to eat the Lord's Supper - They did not come together to eat the Lord's Supper exclusively, which they should have done, and not have made it a part of an ordinary meal.
Verse 21

Every one taketh before - his own supper - They had a grand feast, though the different sects kept in parties by themselves; but all took as ample a supper as they could provide, (each bringing his own provisions with him), before they took what was called the Lord's Supper. See on 1Cor 11:17 (note).
Verse 22

Have ye not houses to eat and to drink in? - They should have taken their ordinary meal at home, and have come together in the church to celebrate the Lord's Supper.

Despise ye the church of God - Ye render the sacred assembly and the place contemptible by your conduct, and ye show yourselves destitute of that respect which ye owe to the place set apart for Divine worship.

And shame them that have not? - Τους μη εχοντας, Them that are poor; not them who had not victuals at that time, but those who are so poor as to be incapable of furnishing themselves as others had done. See the note on Mat 13:12.
