in Paul's writings to the Corinthians (1 Cor. 10:16)
and also 1 Cor 11:27-29
6 Is not the cup of thanksgiving for which we give thanks a participation in the blood of Christ? And is not the bread that we break a participation in the body of Christ?
How clear can Paul get? "The bread IS a participation in the body of Christ" and "who eats the bread... will have to answer for the body and blood of the Lord" This is not just mere bread and wine anymore. This is the body and blood of Christ.
27 So then, whoever eats the bread or drinks the cup of the Lord in an unworthy manner will be guilty of sinning against the body and blood of the Lord.
28 Everyone ought to examine themselves before they eat of the bread and drink from the cup.
29 For those who eat and drink without discerning the body of Christ eat and drink judgment on themselves.
HMMmm...
That PAUL fellow can REALLY be confusing! 1 Corinthians 12:27
Now you are the body of Christ, and each one are a part of it.
