Christianity is an incredibly broad topic. In fact, it is too broad a topic even to introduce it properly. So you are going to "choose your own adventure." You can pursue this course in any of four ways. You make the choice. But the four tracks cannot be combined, and once you set out on one track you cannot come back. The overall requirements are the same; only the content of the material and your papers varies.
