1 Corinthians 16:22

If any man loveth not the Lord, let him be anathema. Maranatha. [Literally, "Let him be devoted to destruction. O Lord, come!" They were the words with which the Jews began their greatest excommunication. Here Paul pronounces a curse against the man who, professing to be a Christian, had really no love for Christ. Though the church can not always detect and punish such, yet the Lord at his coming will find them out. This, therefore, is Paul's appeal to the Lord to do this thing, and he writes the words with his own hand to show how seriously he meant them. For use of the word "anathema," see 1 Corinthians 12:3; Acts 23:14; Romans 9:3; Galatians 1:8-9]
