Hmm seemingly like a proposition, interesting. XD
Well to begin, I wouldn't say that Deism was a faith or religion, or dogma, but rather a belief. I will explain why there is no real adherence too. (I'd also like to point out that it has been a while since I have read the Bible, so I hope I don't misconstrue anything).
I'd say it could have started at around the age of 16, I went to a catholic school, but my family and I were never practicing Christians. I had already read the bible (of my own accord). What really set off the questions though were the inconsistencies with various passages in the bible. Plus after reading various books in philosophy, I questioned fate and hell. That is to say, if fate existed, then hell would only serve as a tool for something God had purposely created, which would seem odd. Not only this but the fact that it says in the Bible that Satan turned his back from God (not literally of course but more figuratively). I think this is extremely impossible... No matter how evil a person is, I believe God will always be there. And if it was meant in the context that Satan disregarded God's teachings or what have you, then I'll explain that later with another subset of my beliefs. XD
Yeah, to put it bluntly, I enjoy the company of the same sex. The bible says this is bad (though to be fair this was not the reason why I no longer believed in Catholicism. Deism took hold of me a year earlier I believe). That being said there was that reason, but also the erroneous statements, as I believe I recall, within the same book, wherein it says that a man should not lay with a man, it also says that wear two kinds of fabric is also a sin. This picking and choosing of scriptures by people today seems to me to be out of convenience and personal vendettas. Again these two reasons was not my main reason to convert. It was more the paradox of the hell/fate thing mentioned earlier.
I realise it would be simple enough for someone to believe in on or the other, but then it got me thinking. I do sort of believe in a kind of Heaven, yet I would call it more like a "source". (I'd also like to mention that all Deists have differentiating beliefs, but they do have all of the same main tennants). I don't like thinking too much of it though, because I am unsure on exactly what happens, but it would perhaps be something similar to the phenomenon seen in the Golden Compass trilogy after the main characters freed the spirits from the Ashphodal-like fields. That is to say people returned to the Earth by way of a sort of energy.
Many people would think that Deists are insecure (because they don't really care about the need for salvation), but this is untrue. A Deist is comfitted by logic. It's almost similar to an Atheist actually. I know one day that I will die, and that some form of God or creator or something in that regard that I cannot explain now will take place. Because I believe everyone is energy (so to speak), it essentially implies that hell is truly unneeded.
That being said, the kind of God I see existing is one that sits back and watches his/her creations. This explains the scientific/logical aspect of a Deist's mind.
I don't believe someone can be born with a faith. Only a parent or other can teach the person, and while a child is not the best to teach a religion too (loss of interest perhaps, etc), it can at least open doors to openess of religions.
Anywho, I hope that all made sense. I tend to ramble on, but I won't really edit the above as it probably is all pertinent.
On a side note though, I remember having a sort of discussion with another member a while ago who I think was a Fundamentalist Christian who had gone to the Iraqi war. It wasn't argumentative, but I did ask a lot of questions, because I was more astounded by his beliefs. I realise it is 'to each their own', but he explained that his actions were justified because he (as a believer in Christ and God) was doing God's job of eradicating terrorists. Not only that but he had mentioned that those who did not believe in his religion would be going to hell. Then I brought up the innocent people, such as children not aware completely what his religion meant, and an isolated tribe who has not had contact with the world. He had said that they would all be going to hell. This was quite disconcerting.
Ramble complete. :3
