INFP
And here is why not INFJ:
Jesus wasn't organized. He never systematized his followers. He never insisted on any one particular ritual. He didn't appear to fit into any mold at all. He could be seen as a wandering bum. He never campaigned for followers. He never worked within the system of church or government that existed back in those times--and an INFJ would. INFJs work within the system. Jesus didn't become a church leader so he could preach his message. Fe vs. Fi. Fe exists within the pre-laid-out protocol of society. It thinks in terms of agreed upon standards. Fi, however, couldn't care less if all the rules are broken, and that's exactly what happened. Jesus pissed the shit out of the existing power structure. His message was clearly beyond social structure.
INFPs are true rebels at heart, much moreso than INFJs. It's an INFP who could stand for something so heretical, so without precedent, but so connected to the heart. INFPs cut their own path, as a defining characteristic. INFJs, by all accounts I have seen, are smart and compassion focused and everything, but they are society people, they strive to live lives that fit into a more well-defined context, and they don't tend to isolate themselves from the system.
