A weak faith, in my opinion. You don't see the Pope freaking out over the TOE, for example.
Part of it might be that they would rather focus on fighting a scientific theory, than going out and doing the hard work associated with Christianity, such as feeding the poor, caring for the sick etc.
I wonder, would Jesus be spending his time fighting to get intelligent design into schools, or would he be down at the homeless shelter caring for society's worst-off?
The same individual who will try to console a parent who has just lost a child in infancy with the words, "The Lord works in mysterious ways" will state categorically that G-d could not possibly have used evolution to further His creation
