Jerome

The more the tongue has sinned, the more it is miserable.

The sword kills the body, but the tongue kills the soul. The tongue knows no moderation—either it is a great good or it is a great evil. It is a great good when it acknowledges that Christ is God, and a great evil when it denies that. Let no one deceive himself into thinking that he has never sinned, for if I have sinned, it is with my tongue. What more monstrous sin is there than blasphemy against God? The devil did not fall because he committed theft, murder or adultery; he fell because of his tongue. He said: “I will scale the heavens; above the stars I will set up my throne, I will be like the most high.”

One who holds his head high in arrogance hates God.
