Christianity as an imperial-aligned religion doesn't happen sure, but I'm not sure it falls apart. Jesuism or "The Way," looks a lot more like the Anabaptist traditions, Quakers, Liberation Theology, Christian Anarchism, and secular "Jesus as moral exemplar" movements.

As to the degree that these are falling apart is debatable. They certainly don't have the strong central hierarchy and universalism that Catholic and Protestant sects have, but they seem to endure.
