16The cup of blessing which we bless, isn`t it a communion of the blood of Christ? The bread which we break, isn`t it a communion of the body of Christ? 17Seeing that we, who are many, are one bread, one body; for we all partake of the one bread. 18Consider Israel after the flesh. Don`t those who eat the sacrifices have communion with the altar?
