To me a lot of what sets Dylan apart is how he's always changing, always reinventing himself, always rebuilding himself. This is a pretty vanilla stance in theory but in practice all the Dylan hagiography is around one single change—the Newport Electric moment. He's still thought of first and foremost as a political folk-rock songwriter which was a stage in a progression. Even people who talk about Protean Dylan are embarrassed by his Christian turn, they try to ignore it pretend it never happened they don't listen to anything he did after Blood on the Tracks
But what makes him great and not just some overhyped folk rocker is the full scope of his career—not just the conversion to electric at Newport, which is central to his hagiography, but many turns and pivots, including the Christian conversion. (Which is one of the parts of his career that is actually STILL subversive and interesting, that hasn't been domesticated and integrated into baby boomer mythology the way the Newport electric moment has been.)
