Interesting. Though R.C. raised and educated, I consider myself a neophyte when it comes to the books of the Bible.
In any case, I would like to reiterate that anyone search for information on Catholicism use official sites and official readings. The OP wants to know about Catholicism.
While the Church has a long and colorful history, there’s a lot of information out there that is subject to interpretation and reinterpretation. I would suggest avoiding this type of research if the OP truly wants to find out about the Church.
This is not to deny that people have had differing views and interpretations over time (and some have been made into wonderful mystery books), I really would stick with official Church teachings and writings since the OP seems to be seriously interested in the Church.
