1 Corinthians 10:21

21. Cannot Ye can do one or the other; but ye cannot do both. It is a cannot arising from the incompatibility of the two things. It was the contrariety of the kingdoms of light and of darkness, and the apostle solemnly warns them to beware on which side they stand.

Cup of the Lord The Jehovah of the Old Testament, who was at war with all idolatries, the Christ of the New Testament, who is establishing the kingdom of light on earth.

Cup of devils This refers to the festal cup at the pagan sacrifices, from which the libations were poured forth, symbolizing the treating the god with wine. “Wherefore,” says Eneas in Virgil, “come forth, O youths, and in honour of so much excellence, wreath your foreheads, bring forth the cups, invoke the common deity, and present your wines.” Whatsoever Jew drank of these cups or ate the meats was denounced as an apostate.

Lord’s table The Rhemish (Romanistic) commentator makes here a desperate effort to show that St. Paul sustains the doctrine that in the sacrament of the Lord’s supper there is a living victim, Christ, repeatedly and literally sacrificed upon an altar. His opponent, Dr. Fulke, very truly replied that neither the word victim, sacrifice, or altar is once used. The Christian holy sacrament is simply selected as the opposite image to the heathen sacrificial feasts, to present strongly the contrast by which the Christian is forbidden to be sharer in the other.

Doubtless as being the successor of, and substitute for, the sacrifices of the old covenant to figure one real sacrifice, once and for evermore offered, the sacrament may be viewed as a symbolic sacrifice. It sustains the same relation that baptism does to circumcision, and that our Sunday holy-day does to the Jewish sabbath. Hence very beautifully did the Council of Ephesus say, “We celebrate in the Churches the un-bloody service of the sacrifice.” And here, as the Council by the word “un-bloody” recognises that the wine is no literal blood, so it follows that the sacrifice is of no literal victim.
