I essentially agree with Nuggin. "Christian" scriptures without Christ might feature a few different names and stories, but I don't think that some sort of evangelical monotheism could have been held back forever.
Oh, you misunderstand me.
I'm not saying they will be "essentially the same". I'm saying they will be literally, word for word, the same.
Christ died on the cross not because there was some guy who was actually crucified, but because the vast majority of solar deities die on the cross with two other men. It's seen again and again and again in mythology from the region dating back thousands of years.
It's all astronomical. The sun's transit across the sky ends at the the southern cross with two companion stars. The sun "dies" for 3 days, then rises again.
There's a reason that solar deities all share the same birth day, the same death, the same "three visitors", the same "companions at death", etc etc etc
I'm saying that there may or may not have been a Jesus. And that person may or may not have said a few choice things. Most likely not, but I wasn't there. That person's life has virtually nothing in common with the story in the Bible which is just a mishmosh of Horace, Mithra and the rest.
