Let no corrupt communication proceed out of your mouth, but that which is good to the use of edifying, that it may minister grace unto the hearers.
All Commentaries on Ephesians 4:29 Go To Ephesians 4
John Chrysostom
AD 407
This means: “whatever edifies your neighbor, say this and nothing more.” … Say “only such as is good.” The flood of words is vast. Paul is right to charge us to use language carefully. He gives us a pattern for doing this. Of what then are we to speak? “Whatever edifies,” he says. Why? “So the one who hears may be grateful to you.” Suppose your brother has committed fornication. Do not lord it over him. Do not gloat. That will not help your brother but damage him. It is as if you were driving a nail into him. If you counsel him, do so in a gracious manner. Show him how to keep his mouth clean. Teach him not to disparage anyone. Make his instruction your first concern. Then you have rendered him a great service. And if you speak with him about abstinence, discretion and alms, all these things soothe his soul, and he will give great thanks to you. .
