Catechesis: Sacrament of the Altar

From this [1 Cor. 10:16, 17] we clearly learn that not only the cup that Christ blessed at the first Supper, and not only the bread that Christ broke and distributed, but also the bread we bread and the cup we bless, is the communion of Christ's body and blood. So all who eat this bread and drink this cup truly receive, and are partakers of, Christ's true body and blood.—FC SD VII:54
