You will kindly note, from your own evidence here, the phrase "...evolution, which has not been FULLY proved even in the domain of natural sciences..."
The reason this document is couched this way is because the Church has, for quite some time now, accepted Darwin's theory of evolution, agreeing with Darwin that the theory of evolution does NOT address the evolution of all that is, and in particular, does not address the earliest origins of life. The mystical uber-extension of Darwinism this is railing against was equally opposed by Darwin.
And, by the way, there's no such thing as proof (as a source of certainty) in any in the natural sciences, as the church fathers who drafted this are well aware.
Keying on Fully as the evidence that the Church accepts Darwinian evolution? If not, what other evidence do you offer about the Church's acceptance of this as man's origin? I am not aware of any and I have checked extensively since returning to the Church. I am happy to take the info I presented to you from the Cathechism of the Church and writings from different Popes and follow their conclusions as being current Church teachings. What is your evidence that the Church holds to Darwinian evolution?
