No, you're not. Your mind is made up. You're a dedicated, true believer. Everything you've offered is confirmation bias from other saints, Catholic priests, etc.. Without the RCC, you're lost.
My mind is made up but I'm curious why @Capernum has a heterodox theology.
So far he's only said "because I went to seminary" which doesn't mean much when some of the greatest theoligians in history disagree and they also went to seminary.
Joseph Ratzinger is one. He's written 66 books on theology.
