The theme I'm using gives these specifications: "Optimal size for logo is 480 pixels in width and between 240 and 480 pixels in height." Logo designs that are appealing to me include the image of a book or books or a cross. Probably not a church. Colors I like are navy/darker blues, forest green or regular green. Probably not red. I like blue with gray and green with gray. "Christianity" could be in one script with the "t" being the shape of a cross. I'm not sure if I want "FAQ" or  have it spelled out like "Frequently Asked Questions." I'm open to designs with both.
