What Is the Content of the Revolazzione?

The Revolazzione is an orderly explanation of what theology is, the fonts of revelation going through apologetics and other things in an orderly fashion. Perhaps someone then would be tempted to say, well, this is a manual. I have a big hand, but it's still just a manual. So maybe it's actually better to start with, well, what is it? Because then it helps to understand why it's a little bit different than at least a summary manual.
