“To seek unity with false prophets without challenging their errors leaves one’s own beliefs open to questions. Those who defend heretics, even if they do not believe in their teachings, are guilty of lending credibility to their heresies, and will be held accountable to God for the souls that are destroyed as a result. It’s up to those that know the truth to defend the Church against false teachers whatever the cost to unity or to personal benefit”
– Al Dager
2 Peter 2:1 But there were false prophets also among the people, even as there shall be false teachers among you, who privily shall bring in damnable heresies, even denying the Lord that bought them, and bring upon themselves swift destruction.
1 John 4:1 Beloved, believe not every spirit, but try the spirits whether they are of God: because many false prophets are gone out into the world.
Romans 16:17-18 Now I beseech you, brethren, mark them which cause divisions and offences contrary to the doctrine which ye have learned; and avoid them. For they that are such serve not our Lord Jesus Christ, but their own belly; and by good words and fair speeches deceive the hearts of the simple.
Revelation 2:2 I know thy works, and thy labour, and thy patience, and how thou canst not bear them which are evil: and thou hast tried them which say they are apostles, and are not, and hast found them liars:
1 Timothy 6:20 O Timothy, keep that which is committed to thy trust, avoiding profane and vain babblings, and oppositions of science falsely so called:
1 Thessalonians 5:21 Prove all things; hold fast that which is good.
2 Thessalonians 2:15 Therefore, brethren, stand fast, and hold the traditions which ye have been taught, whether by word, or our epistle.
2 Timothy 1:13-15 Hold fast the form of sound words, which thou hast heard of me, in faith and love which is in Christ Jesus. That good thing which was committed unto thee keep by the Holy Ghost which dwelleth in us. This thou knowest, that all they which are in Asia be turned away from me; of whom are Phygellus and Hermogenes.
Titus 1:9-14 Holding fast the faithful word as he hath been taught, that he may be able by sound doctrine both to exhort and to convince the gainsayers. For there are many unruly and vain talkers and deceivers, specially they of the circumcision: Whose mouths must be stopped, who subvert whole houses, teaching things which they ought not, for filthy lucre’s sake. One of themselves, even a prophet of their own, said, The Cretians are alway liars, evil beasts, slow bellies. This witness is true. Wherefore rebuke them sharply, that they may be sound in the faith; Not giving heed to Jewish fables, and commandments of men, that turn from the truth.
