Luffy is more like an unknowing disciple or something rather than a direct allegory of Jesus. At least not one that's biblically consistent, unless this is supposed to be his first coming, which it clearly isnt (joyboy/nika has been around for a while). Jesus does not return in the flesh.
Luffy tends to behave in ways that are 'Christ-like' without him even realizing it, and he explicitly rejects being called "a god" on multiple occasions. So more like a human who carries the 'Spirit of God' (or whatever One Piece equivalent may be) with him than God Incarnate. I noticed these things years ago, always had a feeling Fujitora is like an angel of some kind when he was introduced, made a post about it here in case it happens to be correct in the future lol. Usually where there's demons there are angels, and as satan is supposed to be already defeated and exiled to the world, it makes sense that they typically don't interfere. That is if the story follows the same premise of course.
Anyone remember the supposed "leak" from like 10+ years ago that went something like "the final war will happen after luffy unites the marines and pirates against the devil, who will inhabit blackbeard after skimming all the devil fruit powers from the surface of the sea"? Clearly it's not 100% accurate (maybe Oda changed it?) but the 'final villain is the devil' part is absolutely correct, pentagrams and all lol. BB being the final character that Imu/satan possesses is also likely true, though he may not literally end up being called "devil" or "satan".
