Bible Verses About Idle Words And Careless Speech

Early Christians taught that idle, careless, and foolish speech was a real sin and would be answered for before God. Matthew 12:36 is the key Bible text, and writers like Irenaeus, Clement of Alexandria, Tertullian, Cyprian, Tatian, and the Apostolic Constitutions repeat the warning in different ways. They also tied this to careful, restrained speech, avoiding joking, empty talk, slander, and rash words.

The evidence is broad across the 2nd and 3rd centuries, though some later or weaker cards only echo the same idea in general moral teaching.
