You do know, don't you, that John Paul II supported evolution?
I don't think I'd call him full of "despair and hopelessness".
I read more than one thread on JPII and evolution. I never ran across one in which JP said that he was an evolutionist. They all discussed what was proper Catholic theology.
There is no Catholic theology that rescinds the idea of God.
Therefore, the only version of evolution acceptable in Catholicism is one that has God as the creator and guide of all life.
