1 Coríntios 11

27 So that whoever shall eat this bread and drink [this] cup of the Lord unworthily, he will be guilty of the body and blood of the Lord.

28 But let a man examine himself, and so let him eat of [that] bread and drink of that cup.

29 For he who eats and drinks unworthily eats and drinks condemnation to himself, not discerning the Lord's body.
