'Blood' in the Bible

The cup of blessing which we bless, is it not the communion of the blood of the Christ? The bread which we break, is it not the communion of the body of the Christ?

In like manner also the cup, after having supped, saying, This cup is the new covenant in my blood: this do, as often as ye shall drink it, in remembrance of me.

So that whosoever shall eat the bread, or drink the cup of the Lord, unworthily, shall be guilty in respect of the body and of the blood of the Lord.

But this I say, brethren, that flesh and blood cannot inherit God's kingdom, nor does corruption inherit incorruptibility.
