The Pope has said that “there is much scientific proof in favor of evolution, which appears as a reality that we must see and which enriches our understanding of life and being as such.”.
“Proof” and “reality” - yeah - that is sure ambiguous. NOT!
If the Holy Father had particularly wanted to endorse Darwin's theory, he would have done so. The fact remains he did not.
I believe what the Pope was saying is that there is scientific "proof" (at least abundant evidence) for biological evolution — even cosmic evolution for that matter.
But this is what we would expect in a divinely created Cosmos evolving in space and time according to the divine Logos of the Beginning, from Alpha to Omega.
Darwinism carries absolutely no brief for that idea, certainly. Rather, the very contrary is asserted: In a nutshell, Darwinian evolution is not purposeful; it is "random," "unguided," essentially "accidental" and "opportunistic"....
How could you expect the Holy Father to endorse such an idea?
