I'm not sure how to give an exhaustive list of prominent philosophers who are also Christians, but some philosophers who come to mind are: Bas van Fraassen, Michael Dummett (recently deceased), William Alston (recently deceased), Alvin Plantinga, Peter van Inwagen, Marilyn Adams, Robert Adams, Robert Audi, Keith DeRose, Anthony Kenny, Alasdair MacIntyre, Richard Swinburne, Nicholas Walterstorff. idk, there are lots more, but these are some who come to mind. All of them have made significant contributions to areas outside of philosophy of religion or distinctively Christian philosophy (actually, some of them -- van Fraassen, Dummet, for example -- have done very little, if any, work in philosophy of religion).
(Coincidentally, William Lane Craig is not a particularly prominent philosopher, although he's produced some fine work. He's well known in certain circles outside of academic philosophy because he's debated alot of people. Oh, and Craig isn't a fundamentalist. The person who gave the answer about Craig kind of doesn't know what they're taking about.)
