I think any serious discussion of Jesus will demand a more closer, detailed view of the four Gospels. Right now I feel like a few of his more popular points are being brought up as proof of one type or another.
To be blunt, do you think Fi's would never come to utter a truth like "Love your enemies"? I don't think that is exclusively Fi or Fe at all. And so on.
If I were doing a serious canvass of Jesus (or anyone as complex as he was), I'd have to go through each of the four gospels, verse by verse, and write down whatever I saw that might fit in a particular function category. By the end, I should have LOTS of data.
Then you go through and look at various snapshots of him to see what type he might most closely reflect in a given situation (since we're more than our functions, when operating in a particular circumstance).
But it's not a quick undertaking... which is why no one seems to do it.
I think I might have at times said he looked rather INFJ to me. But there still major discrepancies. For example, most INFJ people I know come off as "colder" on the surface, they're very protective of their inner world. Jesus wasn't. He was very warm. And people recognized it and loved him.
So... lotsa hodge-podge.
And I don't think "most Christians" even use the MBTI, let alone try to cast Jesus as something to make him a "universalist" savior. They've got theology for that. They don't use MBTI to prove their faith, and some even shun MBTI because they've got a Bible to say that Jesus was a universal savior teaching universal values.
