Have nothing to do with foolish, ignorant controversies; you know that they breed quarrels. 2 Timothy 2:23
Such talk leads either to a split in the church, or eventually to heresy. People start out arguing decent points about minutiae we can appropriately disagree on. But they end up, by way of arguing, digging in their heels and eventually forsaking the gospel in order to prove they’re right and the other person is wrong.
Have nothing to do with conversations crossing such lines.
When correcting people gently the Lord “may” grant them repentance (vs. 25).
But he might not.
