It’s a chilling warning, but what does it mean?
Whoever, therefore, eats the bread or drinks the cup of the Lord in an unworthy manner will be guilty concerning the body and blood of the Lord. Let a person examine himself, then, and so eat of the bread and drink of the cup. For anyone who eats and drinks without discerning the body eats and drinks judgment on himself. (1 Cor 11:27-29)
It’s an especially chilling warning because, as we read on in chapter 11 of 1 Corinthians, God reveals this (committing the above sins) is why he had been punishing some in the Corinthian church with affliction and even death: “That is why many of you are weak and ill, and some have died.”
What does it mean to take the Lord’s Supper “in an unworthy manner”?! What does it mean to participate in the Lord’s supper, “without discerning the body”?! These are obviously serious sins, given that they warrant such severe and immediate judgement and discipline from God!
