I read this whole thread. I find the God debate fascinating, and of utmost importance for all humans to face. I have EDIT: tentatively taken my place as an Existentialist Catholic Christian (I kind of made that up). I have many things to figure out before I start claiming anything with some amount of certainty. This has been an arduous and painful experience.
Thoughts on other types... (all in my experience, of course)
ENFP... tends to like vague spiritual things...like the New Age movement. Enclined towards theism or unifying force.
ENFJ... I do not know any too well, but the one I know relatively well is a practicing Jew...reformed I think. They seem to like a structured religious belief. Inclined towards theism.
ENTJ... the one I know is surprisingly spiritual...into New Age, but in a very analytical fashion. Inclined towards theism or unifying force.
ENTP... another one that subscribes to vague spiritual beliefs in the vein of ENFPS. It seems to me a kind of belief in the one-ness of everything without taking it too much further. Inclined towards theism or unifying force. Also, a fairly significant amount of agnostics/atheists.
INTP... least spiritually inclined of the bunch. INTPs remind me of sensors in a way with their often exclusive use of hard logic to determine the truth of everything. They don't seem to care about things outside the realms of the concrete or empirically provable. However, I have seen INTPs around different forums who contradict this. Inclined towards agnosticism and atheism.
INTJs... an interesting bunch, I've known one who is Protestant, another who is hopefully spiritual, and a few atheists. A mixed bag really, I can't honestly say what they are inclined to believe.
INFPs... like INTPs though way, way, way, more upset about the implications of materialism/atheism. The often cannot accept anything other than what they deem objective truth. Deep down they yearn for a perfect system (or something) to derive meaning from. I believe this is why they can appear so broken. They are a soulful bunch, but let their perfectionist streak get in the way. Inclined towards agnosticism and atheism.
INFJs... all I know are spiritual in various religions or belief systems...most take this quite seriously. They are usually extremely interested in studying their beliefs thoroughly, and like a structure to their beliefs. Inclined towards theism.
ESTPs and ISTPs... don't really seem to think too much about it beyond some vague hopes. Inclined towards a unifying force.
ESFJ... all the ones I know are quite religious, but in an external "I just believe and that's enough" sort of sense. They like religious structure, like a community church or something. Inclined towards theism.
The rest I don't really know about...
I hope I didn't sound condescending to anyone's beliefs...I was just trying to state them as I honestly perceived them.
