That sounds awesome! I could sort of see a simplistic gradient from black to white with your title in stark white casting a long shadow over everything. Or an object of your Church (do they still use crosses) all sharp and vectored in shades of light and dark with the title aligned along the side of it, casting a black shadow on white ground. Gah, covers are so fun, if only to give a visual reminder that this is what we want to do.

Ignore me and my brain.

The Photoshop in me is strong. (Conceptually, at least, though I don't have the actual design skills to match.)
