1. Korinther 10:16

The cup of blessing--answering to the Jewish "cup of blessing," over which thanks were offered in the Passover. It was in doing so that Christ instituted this part of the Lord's Supper (Mat 26:27; Luk 22:17, Luk 22:20). we bless--"we," not merely ministers, but also the congregation. The minister "blesses" (that is, consecrates with blessing) the cup, not by any priestly transmitted authority of his own, but as representative of the congregation, who virtually through him bless the cup. The consecration is the corporate act of the whole Church. The act of joint blessing by him and them (not "the cup" itself, which, as also "the bread," in the Greek is in the accusative), and the consequent drinking of it together, constitute the communion, that is, the joint participation "of the blood of Christ." Compare Co1 10:18, "They who eat . . . are partakers" (joint communicants). "Is" in both cases in this verse is literal, not represents. He who with faith partakes of the cup and the bread, partakes really but spiritually of the blood and body of Christ (Eph 5:30, Eph 5:32), and of the benefits of His sacrifice on the cross (compare Co1 10:18). In contrast to this is to have "fellowship with devils" (Co1 10:20). ALFORD explains, "The cup . . . is the [joint] participation (that is, that whereby the act of participation takes place) of the blood," &c. It is the seal of our living union with, and a means of our partaking of, Christ as our Saviour (Joh 6:53-57). It is not said, "The cup . . . is the blood," or "the bread . . . is the body," but "is the communion [joint-participation] of the blood . . . body." If the bread be changed into the literal body of Christ, where is the sign of the sacrament? Romanists eat Christ "in remembrance of Himself." To drink literal blood would h…

In this chapter the apostle prosecutes the argument at the close of the last, and, I. Warns the Corinthians against security, by the example of the Jews, who, notwithstanding their profession and privileges, were terribly punished of God for their many sins, their history being left upon record for the admonition of Christians (Co1 10:1-14). II. He resumes his former argument (Co1 8:1-13), about eating things offered to idols; and shows that it was utterly inconsistent with true Christianity, that it was downright gross idolatry, to eat them as things offered to idols; it is having fellowship with devils, which cannot consist with having fellowship with God (Co1 10:15-22). III. He lets them yet know that though they must not eat of things sacrificed to idols as such, and out of any regard to the idol, yet they might buy such flesh in the markets, or eat it at the table of heathen acquaintances, without asking any questions; for that the heathens' abuse of them did not render the creatures of God unfit to be the food of his servants. Yet liberty of this kind must be used with a due regard to weak consciences, and no offence given by it t Jew nor Gentile, nor to the church of God (Co1 10:23 to the end).

10:16-18 Paul affirms the spiritual meaning of sacred meals. In the Lord’s Supper, believers share in the blood and body of Christ (see also 11:17-34; Matt 26:26-28; Mark 14:22-24; Luke 22:19-20). Sharing one loaf unites believers as one body in Christ, just as the pagans’ religious meals unite them with the gods they worship (see 1 Cor 10:19-21).
