To my knowledge no one has a document which is as comprehensive as the CCC. It is my belief that this is the most important document produced by the RCC. It, and it alone, contains the true teachings of the RCC and when one wishes to know these teachings this is the place to go.

Frankly, I think I may refer to the CCC more than the average "Catholic" and know more about Catholic teaching than this self-same "Catholic".
