I'd argue that it's still a bit dismissive to state that the whole thing ended up a dogmatic religion, but perhaps that's splitting hairs at this point.
Having grown up on the Evangelical/pentecostal fringes, I saw much of Christianity as 'dogmatic religion' (not seeing that much of this was present in my denomination too), but now that I'm not a Christian any longer, I've come to realize pretty much all denominations of Christianity contain both significant figures and movements that tend toward the 'non-violence, anarchy and peaceful disobedience' side of things, as well as a lot of dogma.
I've recently found a lot in Zen buddhism that reminds me of Jesus' teaching, except somehow more practical. I can strongly recommend doing some research in that.
