He's right, and it is insanely destructive. Thomas Aquinas said the truth cannot contradict itself, and that no really proven truth can contradict other truth. A Christian has nothing to fear from science - as long as it IS science, and not assertion posing as science.
The evolutionary process really appears to be true* But ever since Darwin's day, unfortunately, it has been used like a crowbar to "prove" - or rather to assert - wildly unscientific claims that Mankind is simply another beast, ot that we have no free will, or There Is No God. This in turn sets off our sola scriptural FReepers who honourably - but mistakenly - feel that they must defend one literal exegesis of Genesis to the death.
*Certainly for all flora and fauna except man. There is an interesting lack of speciation in the fossil record of hominids up to and including "Lucy" which seems to indicate that something unique has happened in Man's case. But the fossil record is as yet too sparse to make supportable conclusions. I am confident that disinterested research will lead us into all Truth.
