I am not a Catholic.
Your gibberish in regards to Luther is excused, moral relativism.
If Hitler accepted Jesus in his heart, he would be a current resident of heaven under your definition. Would he still be a POS or would you afford him the same consideration?
Gibberish? You’re atheist then. I’ve not excused any wrong committed by anyone. Here’s a suggestion, Luther died centuries ago, and here you are apparently filled with poison on account of something he wrote. Find it within yourself to forgive him and let it go. That doesn’t mean you accept his writings that were antisemitic. That is wrong whether you forgive or whether you’re consumed with anger and bitterness. Is he in Heaven? I can’t say. He believed in confessing his sins and asking forgiveness of God.
Hitler was a uniquely vile and evil man to the point that I’d say he was demonic. His garbled rationale involved socialism, fascism, nationalism, Norse Paganism and other occult beliefs, wrapped in a vaguely Christian sounding disguise. He had no love for the state church of Germany, he coopted and perverted everything he could about it. He had no love for any Christian church despite being born Catholic.
Your ire is seriously misdirected.
Why do you hate someone so much? He has been dead for centuries. He helped change the world for the better.
