Well, I haven't caught up on the C. material, however my take on channeling is as follow (deeply subjective, obviously):
Picturing an entity, or even a thought form (i.e: artificially created entity, whether done consciously or not) as a circle one could assume the centre of it to be the essence of it (=divine spark, soul, I, Higher Self, God etc.) it is feasible to assume that not all "Channelers" can access that particular level simply because they are not ABLE to since this point is beyond their own comprehension. Meaning that somebody who believe to be channeling Jesus MIGHT be channeling some LOWER aspect of It/Him, providing that his own ego is not doing ALL the talking (while discretely pretending to be Jesus, always good for the self-esteem). Somebody with a minimal ego (or fluid assemblage point) and who is "closer" to Jesus in terms of evolutional stage will almost certainly be channeling a part of the Jesus thought form closer to its "I"-essence.
