The original text of the christian bible has never had any kind of copyright on it (to my knowledge, if such a thing existed when the individual texts were assembled into a single volume). Some bibles have commentary on the sides or bottom, which is of various help in understanding the point of view of the original author (whoever it may be, someone had to write it) depending on the commentator. Sometimes an entirely new translation of a copy of the original language texts is created. Sometimes there's an index, with the main text highlighted in different colors according to the values they speak about to the person who did the highlighting. In all these cases, it constitutes a new work as a whole that can be copyrighted. The original text is still public domain.
Set aside the fact that it's Judeo-Christian for a moment. Then read the introduction with an open mind while discarding any obvious fluff and ask yourself if there's anything listed there that might be worth learning.
Besides, I've always been interested in human belief. :) In relation to the text above the line, I used to collect bibles and other books about belief (generally published early 1900's) before I narrowed my life down to a backpack.
Maybe I'm getting a bit sentimental for a time when I spent most of my time studying terra incognita
