Commentaries:
Adam Clarke
The cup of blessing - The apostle speaks here of the Eucharist, which he illustrates by the cos habberacah , cup of blessing, over which thanks were expressed at the conclusion of the passover. See this largely explained at the conclusion of the notes on Matthew 26:75, and in my Discourse upon the Eucharist, 8vo. 2nd edit. 1814.
The communion of the blood of Christ? - We who partake of this sacred cup, in commemoration of the death of Christ, are made partakers of his body and blood, and thus have fellowship with him; as those who partake of an idol feast, thereby, as much as they can, participate with the idol, to whom the sacrifice was offered. This I have proved at large in the above tract, to which I must refer the reader, as the subject is too voluminous to be inserted here.
