Forgiveness is not that you have no boundaries. You can forgive someone but if they want to rape you you don't have to drink coffee with them. Still you can pray that they get saved while there is no contact.
Titus 3:10 A man that is an heretick after the first and second admonition reject;
My Bible says "accursed" and doesn't say, "forgive". My bible says, "reject" and it doesn't say "forgive".
Reject them to what? The lowest hell. Accursed is anathama. It means you're damned.
If you want to hold to your beliefs, you couldn't follow the above two Bible verses. When you learn these two verses, then you can grasp what I'm telling you.
