1Co 10:16 The chalice of benediction which we bless, is it not the communion of the blood of Christ? And the bread which we break, is it not the partaking of the body of the Lord?
The chalice of benediction, &c. Which the priests bless or consecrate, is it not the communion of the blood of Christ? And the bread which we break, (so called because of the outward appearance of bread) is it not the partaking or communion of the body of the Lord? See St. John Chrysostom here, hom. xxiv. p. 396. and p. 400. See also the Annotations, Matthew xxvi. 26. — Here the apostle puts them in mind of the partaking of the body and blood of Christ in the sacred mysteries, and becoming thereby one mystical body with Christ. From whence he infers, (ver. 21.) that they who are made partakers with Christ, by the eucharistic sacrifice, and sacrament, must not be made partakers with devils, by eating of the meats sacrificed to them.
Calix benedictionis cui, (or as it is in the Greek) το ποτηριον της ευλογιας ο ευλογουμεν. See St. John Chrysostom, hom. xxiv. No Catholic now-a-days can declare his faith of the real presence in clearer terms than St. John Chrysostom hath in this, and other places: Greek: oti touto en to poterio on, ekeino esti, to apo tes pleuras reusan, &c. He calls the eucharist, Greek: thusian, a sacrifice.
1Co 10:17 For we, being many, are one bread, one body: all that partake of one bread.
We being many, are one bread. Or, as it may be rendered, agreeably both to the Latin and Greek, because the bread is one, all we, being many, are one body, who partake of that one bread. For it is by our communicating with Christ and with one another, in this blessed Sacrament, that we are formed into one mystical body; and made, as it were, one bread, compounded of many grains of corn, closely united together. — From the sacrament of the real body of Christ in the eucharist, he passeth to the effect of this sacrament, which is to unite all those who partake of it, as members of the same mystical body of Christ, which is his Church: and from hence he presently draws this consequence, that such as are members of that body, of which Christ is the head, cannot have any communication with idolaters, or with those that offer sacrifices to idols and devils.
