What beliefs would we consider reasonable for a self proclaimed Christian to hold?

[GrandizerII]

I believe there is very good evidence that there is indeed a spirit (soul) that survives the death of the body. I was in audience with Dr. George Ritchie who wrote the books Return From Tomorrow, and My Life After Dying. He was  pronounced dead twice and ultimately was revived by an injection into the heart. He was chairman of the Department of Psychiatry of Towers Hospital; and founder and president of the Universal Youth Corps. There have been hundreds of books written about near death and out of body experiences. The research is ongoing.

I am strongly of the opinion that Dr. Ritchie's brain was not permanently dead and that he experienced a run-of-the-mill NDE (which I do not accept as evidence of life after death).

Apparently, he also wrote his book decades after the experience, so a lot of the details would've likely been false memories.
