The cup of blessing which we bless, is it not the communion of the blood of Christ? The bread which we break, is it not the communion of the body of Christ?
All Commentaries on 1 Corinthians 10:16 Go To 1 Corinthians 10
Irenaeus of Lyons
AD 202
And adds, "The cup of blessing which we bless, is it not the communion of the blood of Christ? ".
But if this indeed do not attain salvation, then neither did the Lord redeem us with His blood, nor is the cup of the Eucharist the communion of His blood, nor the bread which we break the communion of His body.
