1 Corinthians 10:16 - Ellicott's Commentary On The Whole Bible

The cup of blessing which we bless. — In other passages the cup is mentioned after the bread, and not, as here, before it. The order in which they are placed here has been variously accounted for, as arising either (Stanley) from the analogy to the heathen feasts, in which the libation came before the food, or (Meyer) because the Apostle intends to dwell at greater length upon the bread. The use of the plural “we,” in reference to both the blessing of the cup and the breaking of the bread, clearly indicates that it was in virtue of his representing the entire company present, and not as individually possessed of some miraculous gift, that the one who presided at a Communion performed the act of consecration. On the whole subject of the Eucharistic feasts in Corinth, see Notes on 1 Corinthians 11:17. Communion with the body and blood of Christ is established and asserted in this partaking of the bread and of the cup.
