" All scripture is God-breathed and is useful for teaching, REBUKING, correcting and training in righteousness.. . . I give you this charge [COMMAND]: Preach the Word; be prepared in season and out of season; correct, rebuke and encouragewith great patience and careful instruction" (2 Tim. 3:16-4:2.)
"He [elder/overseer] must hold firmly to the trustworthy message as it has been taught, so that he can encourage others by sound doctrine and REFUTE those who oppose it" (Titus 1:9).
"These, then, are the things you should teach. Encourage and REBUKE with all authority. Do not let anyone despise you" (Titus 2:15).
" Now we COMMAND you, brethren, in the name of our Lord Jesus Christ, that ye withdraw yourselves from every brother that walketh disorderly, and not after the tradition which he received of us. 14 And if any man obey not our word by this epistle, note that man, and have no company with him, that he may be ashamed.15 Yet count him not as an enemy, but ADMONISH him as a brother " (2 Thess. 3:6).
" But even if we or an angel from heaven should preach A GOSPEL OTHER THAN THE ONE WE PREACHED TO YOU, let him be eternally CONDEMNED! As we have already said, so no I say again: If anybody is preaching to you a gospel other than what you accepted, let him be eternally condemned!" (Gal. 1:8).
"When you are assembled in the name of our Lord Jesus and I am with you in spirit, and the power of our Lord Jesus is present, HAND THIS MAN OVER TO SATAN, so that the sinful nature may be destroyed, and his spirit saved on the day of the Lord" (1 Cor. 5:4,5).
"What business is it of mine to judge those outside the church? Are you not to judge those inside? God will judge those outside. 'EXPEL the wicked man from among you.'" (1 Cor 5:12, 13).
"Those who sin are to be rebuked publicly, so that the others may take warning. I charge [COMMAND] you, in the signt of God and Christ Jesus and the elect angels, to keep these instructions without partiality, and do nothing out of favoritism" (1 Tim. 5:20-22).
"Nevertheless, [in spite of your deeds, love, faith, service and perseverance] I have this against you: [Church of Thyatira] You tolerate that woman Jezebel, who calls herself a prophetess. By her teaching she misleads my servants in sexual immorality and the eating of food sacrificed to idols. I have given her time to repent of her immorality, but she is unwilling. So I will cast her on a bed of suffereing, and I WILL MAKE THOSE WHO COMMIT ADULTERY WITH HER suffer intensely, unless they repent of her ways. I will strike her children dead. Then all the churches will know that I am he who searches hearts and minds, and I WILLl REPAY EACH OF YOU ACCORDING TO YOUR DEEDS" (Rev 2:20-23).
And finally:
" Warn a divisive person [HERETIC] once, and then warn him a second time. After that, have nothing to do with him [REJECT]. You may be sure that such a man is warped and sinful; he is self-condemned" (Titus 3:10)
This is more than twice. Goodbye.
