INTP is the smallest percentage of people on earth, because of the INTPishness of people they tend in the main to be without religion. Because of the INTPishness it is very difficult to become a cohesive member of any congregation. INTP's are misunderstood so often in the secular world, in the world of work, compound all that a gazillion times and then you'll understand how difficult it is for both the INTper and the congregation.
So says, local preacher in training, praise group member and occasional leader, me. It took me 38 years to fully analyse the whole being a Christian thing and then it took me another five years before I could surrender totally and without any reserve, but now I am a new creation and loving it and living in Jubilee.
I am not single, I was searching the web for "Being Christian and INTP" and your post came up. Matariki there are plenty of INTP people in here, just hiding their light under a bushel.
God bless
