When I was little a Jehovah Witness told me the Pope was the devil, and scared the **** out of me. I have no doubt that because of that, I strayed from God, and I now pray for her soul may she rest in peace. She was later diagnosed with a mental illness, before she passed away. Jesus did say, you are better off with an anchor around your neck, than to take away the faith of my children.
I was naive in placing my child in a Christian school. I had no idea how rampant the animosity was. I guess I should have known better from my childhood experience. We live and we learn.
You may be naive in believing that “no Catholic teacher or priest has ever taught animosity towards fellow Christians.”
That, simply, is historically untrue.
However, we pray, “Forgive us our debts as we forgive our debtors,” and hope in the present and future truth of your statement.
Sorry you had some bad experiences with your child.
