10:16 The cup of {n} blessing which we bless, is it not the {o} communion of the blood of Christ? The bread which we break, is it not the communion of the body of Christ?
(n) Of thanksgiving: whereupon, that holy banquet was called eucharist, which is Greek for thanksgiving.
(o) A most effectual pledge and note of your joining together with Christ, and ingrafting to him.
10:16 The cup of blessing which we bless. A name applied to the cup used in the Lord's Supper. Paul shows from the nature of the Lord's Supper, and of the Jewish sacrificial feasts, that to eat in an idol feast is an idol communion.
Is it not the communion of the blood of Christ? Is not the cup the symbol of joint participation or fellowship of the blood of Christ.
Is it not the communion of the body of Christ? Is not the bread the symbol of joint participation of Christ's body?
10:16 The cup which we bless - By setting it apart to a sacred use, and solemnly invoking the blessing of God upon it. Is it not the communion of the blood of Christ - The means of our partaking of those invaluable benefits, which are the purchase of the blood of Christ. The communion of the body of Christ - The means of our partaking of those benefits which were purchased by the body of Christ - offered for us.
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.
