I have always thought that ones eternity in Hell was predicated on the rejection of Jesus Christ as the Son of God, not a belief or disbelief in evolution. If other errors in belief are acceptable as something that would condemn one to Hell wouldnt a belief in Santa Clause or the Easter Bunny also qualify? Just ask’n
LOL!
Why does one need to accept Jesus? Sin. If Theistic evolution is true, death and decay is not caused by sin, but by a sadist God. If you believe in one, you can’t believe in the other. The god who created imperfect matter that keeps getting better = death is good. The God who created all things good = death is bad.
