Would you tell the Apostle Paul that? He had plenty to warn about in regard to false teachers. Speaking out against false teaching is not a matter of judging but of discernment.
God tells us to be on the lookout for them and how to identify them. If you can’t or won’t do that, then you are leaving yourself and others wide open for deception. It is NOT a loving thing to do to allow someone to continue in a false teaching that is taking them to hell without warning them.
Galatians 5:12 I wish those who unsettle you would emasculate themselves!
Acts 20: 29-30 I know that after my departure fierce wolves will come in among you, not sparing the flock; and from among your own selves will arise men speaking twisted things, to draw away the disciples after them.
1 Timothy 4:1-5 Now the Spirit expressly says that in later times some will depart from the faith by devoting themselves to deceitful spirits and teachings of demons, through the insincerity of liars whose consciences are seared, who forbid marriage and require abstinence from foods that God created to be received with thanksgiving by those who believe and know the truth. For everything created by God is good, and nothing is to be rejected if it is received with thanksgiving, for it is made holy by the word of God and prayer.
Perhaps you may be false teaching? Are you so very sure of yourself that you set your interpretation of the word above God?
I think there may be a subject, unspoken of just yet, that may be in a certain person’s life.
When we finally get around to that, I think the response will be, “Who are you to judge me?”
