Don’t speak evil of one another

“Do not speak evil against one another, brothers.” (James  4:11 ESV)

Speaking evil of a brother is backbiting

Backbiting: to attack the character or reputation of a person (who is not present).  Or, to involve yourself in any of the following: lie, slander, abuse, spite, gossip, defamation, disparagement, malice, scandal, tale.

Watch out!

Satan is the accuser of the brethren! When you criticize or slander a brother (fellow Christian) you are siding with the devil!

“Then I heard a loud voice in heaven, saying, "Now the salvation, and the power, and the kingdom of our God and the authority of His Christ have come, for the accuser of our brethren has been thrown down, he who accuses them before our God day and night.” (Rev. 12:10)

Such persons do not serve Christ!

“I appeal to you, brothers, to watch out for those who cause divisions and create obstacles contrary to the doctrine that you have been taught; avoid them. For such persons do not serve our Lord Christ, but their own appetites, and by smooth talk and flattery they deceive the hearts of the naive.” (Rom. 16:17-18 ESV)

“If anyone thinks he is religious and does not bridle his tongue but deceives his heart, this person's religion is worthless.” (James 1:26 ESV)

Therefore…

“Let no corrupting talk come out of your mouths, but only such as is good for building up, as fits the occasion, that it may give grace to those who hear.” (Eph. 4:29 ESV)
