(21, 22) Ye cannot . . .--Here follows the special reason why the Apostle desires them not to partake of the wine poured forth in libation to devils, or the table on which meat sacrificed to these devils was spread out as food. Such would deprive them of their participation in the cup of the Lord and the table on which the Lord's Supper was placed. Of course the impossibility was moral, not physical. So the Apostle adds the warning question, Do you in fact do so? Do you do that which is morally impossible, and so provoke the jealousy of our jealous God, who will have no divided allegiance? Surely we are not stronger than He? To such a question there can be but one answer. These words, which are the climax of the argument, are naturally suggested by the passage in Deuteronomy (Deuteronomy 32:15-18), which was evidently in the Apostle's mind all through this argument, containing as it does the striking words, "Rock of his salvation." "They sacrifice unto devils and not to God," and "they provoked Him to jealousy."

Verse 21. - Ye cannot. It is a moral impossibility that you should. The Lord's table. This is the first instance in which this expression is used, and it has originated the name. The table of devils (see Deuteronomy 32:37). In the fine legend of Persephone, she might have been altogether liberated from the nether world if she had eaten nothing since her sojourn there; but unhappily she had eaten something, though it was only the few grains of a pomegranate; and hence she must leave the upper air, and become the Queen of Hades.

10:15-22 Did not the joining in the Lord's supper show a profession of faith in Christ crucified, and of adoring gratitude to him for his salvation ? Christians, by this ordinance, and the faith therein professed, were united as the grains of wheat in one loaf of bread, or as the members in the human body, seeing they were all united to Christ, and had fellowship with him and one another. This is confirmed from the Jewish worship and customs in sacrifice. The apostle applies this to feasting with idolaters. Eating food as part of a heathen sacrifice, was worshipping the idol to whom it was made, and having fellowship or communion with it; just as he who eats the Lord's supper, is accounted to partake in the Christian sacrifice, or as they who ate the Jewish sacrifices partook of what was offered on their altar. It was denying Christianity; for communion with Christ, and communion with devils, could never be had at once. If Christians venture into places, and join in sacrifices to the lust of the flesh, the lust of the eye, and the pride of life, they will provoke God.Ye cannot drink the cup of the Lord, and the cup of devils,.... 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.
