The Greek adjective autokatakritos is a compound of autos (self) and katakrinō (to condemn). It means self-condemned — condemned by one's own actions, words, or conscience. A hapax legomenon, appearing only in Titus 3:11. It describes a person whose own behavior renders any external judgment unnecessary.
Titus 3:10-11: 'Warn a divisive person once, and then warn them a second time. After that, have nothing to do with them. You may be sure that such people are warped and sinful; they are self-condemned.' Persistent division in the church is a self-condemnation. Our own standards condemn us before God condemns us (Romans 2:1). The mirror of our behavior reflects our spiritual state.
