One of the most curious things about Christianity, is how most of the sauce in the plate doesn't even come from the figure their very religion is meant to be based on. The idea that followers of a religion about a figure, are spending most of their time talking, reading and doing stuff unrelated to the figure they meant to follow is such a human thing to do.
After 2k years of divergence, what is there in common with that figure. Can't read or speak his language, experience his culture or the geopolitics of his world. Everything is seen through 2k years of subjective lenses that people with various goals give to you.
At what point, do you call it a day or focus on the Gospels exclusively? Because that's arguably as close as you can get to him. Everything else seems secondary accounts of secondary accounts and people claiming to have authority to speak on behalf of someone who can't refuse that anymore.
“Another parable put he forth unto them, saying, The kingdom of heaven is like to a grain of mustard seed, which a man took, and sowed in his field: Which indeed is the least of all seeds: but when it is grown, it is the greatest among herbs, and becometh a tree, so that the birds of the air come and lodge in the branches thereof.”
