Hi Blackswan,
I was raise Catholic, then was a JW for 35 years, and now I am currently a practicing Catholic again. The Catholic Church does not take an official position on this matter, but leaves it to one's conscience. How does it work then, when dealing with original sin?
Historic Catholic teaching for nearly 2,000 years is that God "formed" man, and gave him a soul. Reference how Genesis words the text shoing human are made or formed from the dust of the ground, mthus allowing for the forming processes of evolution of the human species. Once the "formed" human received a soul, he became like God as a sentient self-aware being. It was not Adam's body that sinned, but his mind and heart, his soul that sinned. It was Adam's soul or spirit that died the day he disobeyed. It was the human soul that Jesus came to save. This is why Jesus is referred to in scripture as a "life-giving spirit."
It is the Jehovah's Witnesses who confuse everything by putting emphasis on the physical body, the physical and material rewards, and ignores the truly spiritual aspects of the Christian faith.
