The INTP profile at INTP.org says the following:
This got me thinking about God. Trying to grasp His nature (whether you believe He exists, as I do, or whether you don't) is an inexhaustible avenue of abstract analysis for INTPs which fits the criteria mentioned in the above quote perfectly. There is a prevailing assumption that most INTPs are atheists or agnostics, but the concept of God does fit in with the INTP's desire to discover the "big picture" in his or her search for ultimate truth.Indeed, most primary interests of an INTP are things which he cannot fully understand, usually because they are highly complex or have some exotic, mystical element that does not yield to analysis. This is the real reason why INTPs are drawn to complexity: anything simple is too quickly understood and cannot hold the fascination for long.
Could classical theologians like Anselm and Aquinas, who spent their lives pondering the nature of The Supreme Being, have been INTPs?
