Being INFJ, and me, i have allways been concerned with the reality and truth of the essence of the matter. If there is something real and, especially concerning spirituality and religion, true at the base of whatever system of beliefs, then i'm interested. Now, during my relatively short 30+ life i have managed to work through three phases of religious (or, as in the first and second phase, pseudo-religious) beliefs, of which i am still residing in the third.
First phase: "Science" based, cultural agnosticism. I was brought up in a secular environment where natural science was the base model for answering all the fundamental questions of life, the universe and everything.
Second phase: Being not contempt with having even the basic questions of life, the universe and everything left unanswered by natural science i kind of got the feeling that natural science (as natural science) was not really possesing the means to answer those questions. As a young souldiver i turned to shamanism. "If i can experience it - it's real". So i experienced years of tons of mindboggleing, lifeturning, selfdeveloping, realitystretching, serious, real spirituality (You know, the: "Wooow, are you really the same person. My Good, you've really developed!"-kind). And then my gf broke up and none of it mattered.
Third phase: Being a young mature, the original Q's of It All started to emerge once again. The only experience from phase two that really kept with me in phase three was one of Jesus Christ. So, being terrified of becoming a christian (and then, in my mind at that time, of course having to reject what i saw as perfectly acceptable scientific beliefs) i started an intence study of christian and scientific beliefs. It seemed to me, and still seems, that my teenage feelings were on the right track. I quickly learned the difference between science as science, and "science" as a term for naturalist philosophy (which, in short, tries to answer all the fundamental questions of life, the universe and everything from the viewpoint of natural science). The latter, with its hillarious problems of self-righteousness and logical-philosophical incoherence, gave both my high IQ and EQ a good laugh and i eventually ended up a fully fledged christian (in experience, belief, faith and practice).
So, short answer: INFJ and christian.
