Trinity - Part I

As I grew up and suddenly religion became a subject of the most interesting conversations I have ever had, I soon took an interest in shortening the length of the initial part of the conversation. A pattern was evident, and that was the finding out about the other person. After knowing that the labels were out there, it became a lot simpler to ask which of the 3 main categories would they fall under.
As a non believer, I tend to look at people in one of three ways:

• Atheist
• Agnostic
• Theist

It seems to me so far that there are no more categories, only sub categories of those 3. As soon as a religious debate starts and in such debate a non believer side exists, the debate becomes a lot clearer once you know to whom of those 3 types are you debating with.

So, what exactly are these 3 categories? How do they sub divide? Why do I start off with these 3? That is what we will see in coming posts.
