“If your brother or sister sins, go and point out their fault, just between the two of you. If they listen to you, you have won them over. 16 But if they will not listen, take one or two others along, so that ‘every matter may be established by the testimony of two or three witnesses.’17 If they still refuse to listen, tell it to the church; and if they refuse to listen even to the church, treat them as you would a pagan or a tax collector. ~ Matthew 18:15-17
Leviticus 19:17
17 “‘Do not hate your brother in your heart. Rebuke your neighbor frankly so you will not share in his guilt.
Brothers, if someone is caught in a sin, you who are spiritual should restore him gently. But watch yourself, or you also may be tempted. ~ Galations 6:1
Romans 16:17
17 I urge you, brothers, to watch out for those who cause divisions and put obstacles in your way that are contrary to the teaching you have learned. Keep away from them.

Titus 3:10
10 Warn a divisive person once, and then warn them a second time. After that, have nothing to do with them.
1. How great an evil real heresy is, not lightly therefore to be charged
upon any, though greatly to be taken heed of by all. Such a one is subverted
or perverted—a metaphor from a building so ruined as to render it
difficult if not impossible to repair and raise it up again. Real
heretics have seldom been recovered to the true faith: not so much
defect of judgment, as perverseness of the will, being in the case,
through pride, or ambition, or self-willedness, or covetousness, or such
like corruption, which therefore must be taken heed of: "Be humble,
love the truth and practise it, and damning heresy will be escaped.’’ 2.
Pains and patience must be used about those that err most grievously.
They are not easily and soon to be given up and cast off, but competent
time and means must be tried for their recovery. 3. The church’s means
even with heretics are persuasive and rational. They must be admonished,
instructed, and warned; so much nouthesia imports. 4. Upon
continued obstinacy and irreclaimableness, the church has power, and is
obliged, to preserve its own purity, by severing such a corrupt member
which discipline may by God’s blessing become effectual to reform the
offender, or if not it will leave him the more inexcusable in his
condemnation. Matthew Henry's Commentary
