Who is supposed to “police” the Lord’s Supper to make sure that no one is improperly partaking?
We are not told to “police” the Lord’s Supper. We are told to warn people that God Himself will judge people who imporperly partake of it. 1 Corinthians 11:26-32 26 says, “For as often as ye eat this bread, and drink this cup, ye do shew the Lord’s death till he come. Wherefore whosoever shall eat this bread, and drink this cup of the Lord, unworthily, shall be guilty of the body and blood of the Lord. But let a man examine himself, and so let him eat of that bread, and drink of that cup. For he that eateth and drinketh unworthily, eateth and drinketh damnation to himself, not discerning the Lord’s body. For this cause many are weak and sickly among you, and many sleep. For if we would judge ourselves, we should not be judged. But when we are judged, we are chastened of the Lord, that we should not be condemned with the world.”
It was the Lord Himself that was judging the Corinthians who were improperly partaking of the Lord’s Supper. Many of them were weak and sickly because of it, and many had even died. It is a very serious warning that we are to give, and then we are to leave it to the Lord.
