The Bible speaks of, as I understand it, people ascending up to their afterlife. Burial customs in the Western world seem to reflect the need to have a complete body after death.
As time past, the idea of an in tact body going somewhere else for its after life became just too far fetched. That’s when the “soul” became popular.
The problem with the “soul” is it really requires a mind to be a comprehensible concept. How can someone meet lost relatives with no brain to remember them?
The Resurrection story did not involve bringing a soul back to life, but an entire body.
The attempt to substitute the soul for an in tact body made the afterlife concept even less believable. Apologists would have been better off saying, “This not something you can expect to believe without allowing yourself to enter the world of magic. The entire body leaves the grave and goes to heaven or hell.”
I remember reading some 30 years ago a quote from a professor in a large main line denomination seminary. It was something like, “You will never hear a faculty member here say there is a literal life after death. Students can decide for themselves and preach whatever they wish as pastors.”
Trying to explain an afterlife as either a body from the grave or as a soul with no brain or consciousness is challenging indeed.
It’s easier to conclude life ends at death.
