rwp@1Corinthians:10:16 @{The cup of blessing} (\to potrion ts eulogias\). The cup over which we pronounce a blessing as by Christ at the institution of the ordinance. {A communion of the blood of Christ} (\koinnia tou haimatos tou Christou\). Literally, a participation in (objective genitive) the blood of Christ. The word \koinnia\ is an old one from \koinnos\, partner, and so here and kjv@Phillipians:2:1; 3:10|. It can mean also fellowship (Galatians:2:9|) or contribution (2Corinthians:8:4; kjv@Phillipians:1:5|). It is, of course, a spiritual participation in the blood of Christ which is symbolized by the cup. Same meaning for \koinnia\ in reference to "the body of Christ." {The bread which we break} (\ton arton hon klmen\). The loaf. Inverse attraction of the antecedent (\arton\) to the case (accusative) of the relative (\hon\) according to classic idiom (Robertson, _Grammar_, p. 488). \Artos\ probably from \ar\, to join or fit (flour mixed with water and baked). The mention of the cup here before the bread does not mean that this order was observed for see the regular order of bread and then cup in 11:24-27|.
