@JonC Interesting quote I found in an old textbook.
"But where did the soul come from? A few thinkers maintained the Origenist theory, created by God,
the soul pre-existed the body to which it was assigned as a penalty for its sins. Didymus the Blind, for example, taught along these lines, as did the followers of the Spanish heretic Priscillian (+ 385). Victorinus seems to have held a variation of the same doctrine. Most of the Greek fathers, however, rejected this view, which was to be formally condemned in the sixth century. Augustine, too, reacted against the pessimistic valuation of the material order and the suggestion that the body serves as a prison for the soul which it implies. The prevalent Greek theory was creationism, i.e. that each individual soul was created independently by God at the moment of its infusion into the body. Western writers like Hilary, Ambrose and Jerome shared it, teaching that the soul was spiritual and immortal, being extended through the whole body, although existing particularly in a special part of it. Pelagius and his disciples, it need hardly be said, accepted creationism, which harmonized well with the general position." ~ Early Christian Doctrines, J.N.D. Kelly, p. 344-345, Harper One, 1978
The bolded part is something Joseph Smith found appealing when he concocted his blasphemous movement.
