Interesting My son is now 10 years old. When he was 6 he was told that he was going to Hell because he was not Christian. Keep in mind that my wife and I neither pushed, nor pulled him in any religious direction, knowing that until theology was important to him he should just be a child.
One of the first things he asked about was Christianity. As much as my wife hated me doing it, I gave him my Childrens' Bible (from my Grandmother - I'd kept it about 20 years) for a taste of the stories and attempted to explain what I could about the religion. I did explain that religion is a personal thing and only he could decide what he wanted to believe. I also explained that I was not a Christian, however if he wanted to go to Church or Sunday School I would be more than happy to take him.
My son has a better grasp of the social skills required to handle a religious discussion than most Christian children his age - simply because he has not been told that anything theological is "wrong" - which is the case. He has not, as yet, selected his religion - which will be his choice when he decides that's something that he wants in his life. His mother and I have discussed his future, and are willing to accept any non-cult religion, be it Christian, Mormon, Baptist, Catholic, Jewish, Buddhist, Satanist, or Athiest. As well as plenty that I haven't mentioned
I think one of the biggest downfalls of mainstream Christianity is the insistance that other paths are less valid than others. My personal opinion on religion and theology should not affect your opinion unless through conversation and debate you reach the same conclusions that I have, and vice versa. I'm not opposed to showing people what *you* believe, however when it comes right down to it it is a belief, not a fact.
Sorry for the rant, but I thought y'all might want one Pagans method of dealing with religious questions from the young'uns 8)
