If I could receive an honest answer from Creationists on here with regards to the following question, I think it could better advance the dialogue:
Is your adherence to creationism primarily due to your convictions based on science, or primarily because you feel creationism (6-day creation, young earth, no evolution) is the ONLY model in accord with Catholic teaching?
And just a further thought in anticipation of the answers: I think, deep down, many creationists (even on here) fear evolution because it somehow casts doubt on the Faith. Even for those creationists who admit you can be Christian/Catholic and accept evolution, there seems to be a distrust with it, precisely because their conception of the Faith is bothered by it.
Whereas, on the other hand, Christian evolutionists (i.e., my shorthand term for those of us who accept evolution, even of the human body) see no threat whatsoever with the findings of evolution. There is NO inherent contradiction between evolution on the one hand, and the reality of God’s Providence, God’s Creation, the Fall and Original Sin, the goodness of creation, Redemption, and related topics. Surely, some creationists on here DO perceive contradiction and incompatibility. But the Church’s magisterium, the theological consensus, and lay/popular ministries and organizations (Catholic Answers, blogs, EWTN, etc.) have clarified over and over again that the findings of science, even regard to evolution of species, age of the Earth, and evolution of the body, do NOT inherently pose difficulty with any Catholic dogma.
Also, I’m a bit perplexed by attempts by some on here to cite pre-Darwinian theological descriptions as a basis for a Catholic scientific view of human origins or creation. We have NO reason to expect theologians and church leaders pre-Darwin to even try to reconcile Genesis with evolution (or other scientific findings, e.g., old Earth). We should reasonably expect that, while some prominent thinkers (Augustine, Origin, Aquinas) would be fine with evolution, or a non-literalistic/scientific Genesis account, that just as many would take it for granted. Just like geocentrism: No reason to doubt Earth was center of the cosmos until data suggested otherwise. Mere assumptions can’t be taken as theological FACT.
