From the site you quoted at length:
“Concerning biological evolution, the Church does not have an official position on whether various life forms developed over the course of time. However, it says that, if they did develop, then they did so under the impetus and guidance of God, and their ultimate creation must be ascribed to him.
Concerning human evolution, the Church has a more definite teaching. It allows for the possibility that man’s body developed from previous biological forms, under God’s guidance, but it insists on the special creation of his soul. Pope Pius XII declared that “the teaching authority of the Church does not forbid that, in conformity with the present state of human sciences and sacred theology, research and discussions . . . take place with regard to the doctrine of evolution, in as far as it inquires into the origin of the human body as coming from pre-existent and living matter—[but] the...”
Unfortunately, the Catholic Church has been compromised by evolutionary thinking since Vatican II. The infamous heretic, Teilhard de Chardin was allowed to desecrate the Catholic Church with his quasi-Hindu pantheist evolutionary system.
Rather than the obviously compromised, fence-straddling site you authoritatively quoted, please visit the Catholic Kolbe Center for the Study of Creation. Below are some passages from a Kolbe Center essay entitled, “Christ the Exemplar Cause of Creation, Eliminates the Possibility of Evolution,”
“Creation is, as it were, a book. Every creature is a sentence or a word in this book. The Author and Publisher is the Triune God. It is the task of human and angelic intelligence to read God’s thoughts from this book and co-operate with Him. The theme, the dominant idea that runs through each sentence—even each word—is the Word made Flesh, the Incarnate Word of God, Jesus Christ, because this Word says everything. This is why the Archangel says to Blessed Mary at the Incarnation, “No word will be impossible for God.” Evolution is not a word. It cannot be found in this book or in its theme. It is a fable (cf. 2Tim 4:4), a “strange doctrine” of which St. Paul warned us against so long ago.
Chardin made the bold claim that evolution “is a general condition to which all theories, all hypotheses, all systems must bow and which they must satisfy henceforth if they are to be thinkable and true.” This is patently false since no evolution is possible in Christ. Rather, his description of evolution’s supreme place fits the Christ, the Word, Truth Incarnate. It is to Him and His name that we must bow. It is “through Him and with Him and in Him” alone that all theories, all hypotheses, all systems must submit and satisfy if they are to be thinkable and true.
The true Book of Creation, Christ, predicted Chardin’s ideas in the lives of the Israelites making their way through in the desert of Sinai. King David relates in Psalm 105: “They made a calf in Horeb: and they adored the graven thing. … they changed their glory into the likeness of a calf that eateth grass…” (19-20). In making and worshipping the golden calf, these Israelites radically departed from the theme of creation’s book, the Word made flesh, by trying to write, as it were, “we are made in the image of beasts…because we came from the beasts; and we are, therefore, like the beasts. There is some equality between us.” We know the outcome. They proceeded to act like beasts, became beastly, and were destroyed.”
No defense against Teilhard de Chardin, participant in the Piltdown Man hoax.
