1 Corinthians 10:21 Meaning and Commentary

1 Corinthians 10:21

Ye cannot drink the cup of the Lord, and the cup of devils,
&c.] Not only they ought not, but they could not rightly, truly, and really drink the cup of wine in the Lord's supper, in the true faith of Christ's bloodshed, and his sacrifice offered up for them, in remembrance of his love, and to the honour of his name; and also the cup of wine of libations, poured out and drank to the honour of the Heathen deities; these things are utterly inconsistent; no man can serve two masters, God and mammon, or God and Baal; nor is there any concord between Christ and Belial, or agreement between the temple of God and idols:

ye cannot be partakers of the Lord's table, and of the table of
devils;
no man can spiritually, however he may externally partake of the entertainment provided, on the table of the Lord, at his supper instituted and kept in commemoration of him; and also with gust and pleasure, and without any concern for the peace of weak minds, and the honour of God, eat things set upon a table in an idol's temple, and before the idol, and as sacrificed unto it.

1 Corinthians 10:21 In-Context

19 what then do I say? that an idol is anything? or that a sacrifice offered to an idol is anything? --
20 [no,] but that the things that the nations sacrifice -- they sacrifice to demons and not to God; and I do not wish you to come into the fellowship of the demons.
21 Ye are not able the cup of the Lord to drink, and the cup of demons; ye are not able of the table of the Lord to partake, and of the table of demons;
22 do we arouse the Lord to jealousy? are we stronger than He?
23 All things to me are lawful, but all things are not profitable; all things to me are lawful, but all things do not build up;
