There has been a lot of talk lately about how the Catholic Church as embraced evolution whole-heartedly and that the Church completely ignores the creation stories fond in Genesis. Let me try to explain where Catholics stand.
First, the Catholic Church has no official position on evolution. Did God create man in a day? We don’t know, we weren’t there. What Church does say is that IF evolution is true then it was guided by the hand of God, not random chance. Also, IF evolution is true then it is only true for the physical body; the soul was imparted as a singular action and the soul has not and cannot evolve.
A Protestant once asked me how this fits with the Bible. He said that it is important that humans did not evolve because if they did then Genesis is wrong to say that death was introduced only after the sin of Adam and Eve. If evolution is true then the creatures we evolved from had to have died over the ages that it took for us to evolve. To him, this is a direct contradiction to the Bible.
Does Genesis really say that sin caused death? Yes, but what kind of death? God said “the day you eat the fruit you will surly die”. Adam and Eve ate and did NOT die! Hmm, was God wrong? Or was he talking about another type of death?
I mentioned above that Catholics believe the soul did not evolve and cannot evolve. The soul is the eternal part of the human person, the part that either spends eternity with God (lives) or is separated from God (dies). Catholics say that yes, Adam and Eve died when they sinned, they broke their connection with God, they killed their eternal part, they killed their souls.
Did our human bodies evolve from some other creature? I don’t know or care. What matters to me is that my soul was given to me directly by God and that never changes.
