I might be on board for this if it weren't for the fact that mainstream Christianity puts a pretty clear wedge between the sacred/divine and the profane/mundane. I think you can argue that Christian mystics lean towards pantheism/panentheism - as they tend to deliberately blur that sacred-profane dichotomy, but mainstream Christianity does not.
The trinity blurs it and eastern orthodox took a different approach.
