I tend to see atheism as merely another religion. See little difference between fundamentalist and hardcore atheists (which I see more as a J thing).
Agnostics I see more as a TP thing in general and tend to relate to them better than hardcore atheists or religious fundamentalists. Feel more at ease with a group of FPs and TPs not having "harsh" arguments over the dinner table about religion in general (but not always). I have always thought war over religion was not only stupid but ludicrous (although I see the big picture that there would have been war anyway and religion was just handy propaganda to move the masses)
Find most Fs believe in something regardless if it is new wave spiritualism or old school religion.
I am an INTP have been brought up Roman Catholic. I like a lot of the ritual of the Roman Catholics yet in general don't go to church much more than once a month. Although divinly inspired and in parts beautiful, I find much in the bible which is doubtfully and irrelevant.
My TP allows me to muse over the nature of God.
My N gives me "faith" there is a God.
My "I" makes my relationship with God a more individual one and less of a community thing. I care less about what other people believe when it comes to God. Ideally people will get whatever they wish for and go to their own chosen heaven or otherwise "rest in peace" knowing they were right about no god or any other applicable theory which makes them content.
