I simply don't believe in vengeful gods anymore...The OT God, which is merely repeated in Revelation, for some reason (it's largely based on Isaiah, some of it word for word, even) isn't my cuppa.
I find what some term Pauline Christianity rather unpalatable, I think he was going back to the Jewish God and Jewish law just a bit, which is to be expected from a former rabbi!
But, it is one extension of Christian belief, I suppose. I tend to think of Paul as the first real big split of Christian belief, he obviously carried a lot of weight. Obviously, even then, there were those who disagreed with him for better or worse, but for some reason, Pauline Christianity became the basis for the majority at that time, at least, in the NT version of things.
I'm a Universalist, and to be honest, the only part of the Bible that floats my boat is the Gospels and some of the Psalms...even those I take with a grain or two of salt, but I do find Christ appealing, as do many people, even non-Christians. However, I find Buddha equally appealing. I also love reform Judaism and elements of Paganism. I've learned a lot from atheists, but I'm not committed enough to be one...I find it too restrictive, I have too much of a love of the potential or possibility of the metaphysical.
I'm sort of a Jewish Buddhist Christian Pagan, I guess. I take only what I think are the best parts of any belief system, examine them, and incorporate what appeals, and it's quite eclectic, although I find it interesting that all those belief systems have quite a bit in common, more than some people would like to think. I don't believe in "one size fits all" beliefs or ideas, so it works for me.
