I get it, I was raised Catholic. And you're basically right from what I was taught. I just never was able to wrap my head around even needing the intermediary if God were omnipotent in the first place.
Indeed, I basically thought the same as well. I mean, I understand how it all came about, it was never something I really agreed with or understood well. I've never really bought into the idea of needing an intermediary. It sorta makes sense though. Never was a deal breaker for me.
