The company is called Marcher Lord Press and their guidelines for writers explain their requirements. A book has to have a Christian worldview before they'll be interested in it, and (more surprisingly) they aren't looking for YA.
They also have a very different business model from a large publisher:
". . . Marcher Lord Press offers no author advances. None. Authors receive a much higher royalty rate, but get nothing in advance. (Neither do they pay—Marcher Lord Press is not a vanity press or self-publishing entity.)"
They go on to say that their business plan calls for only online sales. If you're at all interested, you should check it out.
