'Blood' in the Bible

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

Likewise also the cup, after they had eaten, saying, "This cup is the new covenant in my blood. Do this, as often as you drink [it], in remembrance of me."

So then, whoever eats the bread or drinks the cup of the Lord in an unworthy manner will be guilty of the body and the blood of the Lord.

But I say this, brothers, that flesh and blood is not able to inherit the kingdom of God, nor can corruption inherit incorruptibility.
