Thanks for quoting the passages, that helps a lot. Those indeed are the letters that I was talking about. The way I see those passages is that they were written by men that were doing their best to teach the way to run a church with what they understood from God. In short, they are the first written attempts of church doctrine. Much as all different sects of the faith do now, such doctrine continues to be reevaluated and rewritten.
Also, it should be noted that there were several different books of the New Testament that weren't accepted by the Church. The ones we have now simply the ones that "made the cut."
In the end, yes I do believe Hell is eternal. However, I can't see any inherently good person going there for simply not believing in God during their time on earth. Being a skeptic isn't a sin IMO.
