This question is important because the humanitarian example of Jesus is more palpable than the supernatural aspects of the Christ myth
Of course. But how that relates to salvation seems to be elusive on this baord.
--proving the existence of said supernatural forces is extremely problematic, as I’m sure you're aware.
I am.
In short, you seem to be saying that Mainstream Christianity condemns me to hell
Not in the least. The overriding principle of MCism is that God is Just, and that only God knows who is condemned and who isn't. That kind of judgementalism, thankfully, is not a big part of the conversation.
despite the fact that A) I acknowledge the humanitarian value of Christ's example,
Yes, that's good.
and B) I at least try to follow that example.
Wonderful! But that has nothing to do with salvation, as I've indicated in a previous post.
It seems to me that Mainstream Christianity teaches that a belief in supernatural phenomena is more important than personal righteousness.
For what? Salvation? It certainly does not. Personal righteousness is entirely separate. What Christianity teaches is that I am no more righteous than you are, and you no more than me. (the former certainly being true!!)
Rewards and punishment is an important part of Christianity. E.g., Heaven = eternal reward; Hell = eternal punishment.
Wrong. Christian rewards have to do with the administration of the 1000 year reign of Christ, and past that, the administration of heaven.
I’ll go with Buffalo’s response, here.
I'd rather have your response.
Wouldn't dream of it! :)
Great! I look forward to more.
