The best expanation for 'Jesus' I've ever read which makes any sense is by John Marco Allegro in his The Sacred Mushroom and the Cross where Jesus is the sacred mushroom. Ie., making sense of the 'God and/or Word made FLESH'--ie., the mushroom is actual flesh right?
Also this motif (though of course the Christians specifically make out this is a real even that happened in history. Not the shroom part tho lol) is deeply connected with ancient paganism and its beliefs that the sacred mushroom they eat was Dionysos, etc etc, and when they eat 'him' they became possessed by him
Now as well as that, the archetype of Jesus obviously has effect on human Imagination because opeople, including athiests' who have had NDEs reports sometimes they meet a shining loving being they say was Jesus. I have also read this powerful report from someone who had Ayahuasca who also claims to have met Jesus in thier trip and been healed.
