I respectfully disagree with your first assertion; I'm most familiar with the shamanism around Kamchatka, but it didn't seem anything like Christian ritual to me, and I think it'd be a mistake to over-emphasize whatever residual similarity Christianity may have had with shamanism. The defining features seem to be things like animal guides, nature worship, elaborate (but very different even between shamanistic regions) cosmology, and entheogen use.
When I was a devout christian myself, I found that they engage in a great deal of subtle group-based energy work, egregore work, ancestor worship, etc. They just use different terminology for it all. These aspects go back the the earliest christian church. Just because they choose to use different terminology, and then promote their own practices while condemning anyone using terminology outside their sect (ie religious xenophobia), doesn't mean they actually *are* doing something different.
