" the same as any other history book" The Bible is not one single work, it is more like a whole library where assorted writings of all kinds (originally as old parchment rolls) have been gathered together. At various times, the books included in the anthology have been blitzed to remove those that didn't suit the image that the religious authorities wished to project (the NT gospel by a WOMAN wasn't included for very long)
Not long after Jesus' death, the Roman grip on the country tightened, and potential troublemakers, such as the Christians with their message of obedience to a higher power and their perceived links to nationalist terrorists, were unpopular with the authorities. This led to secret meetings, and an emphasis that persists to this day on enduring persecution from non-believers, and a serious weeding out of included accounts, so that what remains is mostly about a beleaguered organisation looking forward hopefully to God coming down in glory to take the elect up to Paradise and annihilate the ungodly.
The collection that we know today as "The Bible" contains history in the Old Testament, yes, but also a law-book, a genealogy of royalty (to prove they had a legitimate right to the throne) some biographies of famous historic figures, a second lawbook, a series of erotic poems by King David, and so on.
The second part contains accounts of the foundation and early spread of Christianity, but as history it contradicts itself and some of it is at odds with all other history written at the time. There are four conflicting accounts of the life and ministry of one of the many self-elected Messiahs who emerged when the country was at a low ebb politically and religiously, and tried to revive the ancient pride in the being God's people. These gospels were written a minimum of a hundred years AFTER his death and incorporated stories passed down by word of mouth - they must have undergone considerable editing and polishing in that time, and tales of some of other candidates for messiah-ship must have crept in.
A large proportion of the New Testament is given over to the letters of the convert Paul to satellite groups in other countries (but none of their replies seem to have been preserved). They show history, all right, but it is the history of how Paul energetically shaped the early church to his design, and imbued it with a lot of his prejudices. He comes over as a misogynistic micro-managing boss with little time for any opinions from anyone else in the organisation. Perhaps his colleagues in Central Office encouraged him to go on foreign tours so as to get on with their work in peace?
The NT ends in Revelations - with a vision of the end of days by a prophet in a trance - probably about as accurate as the psychedelic visions of a 60s flower-power guru under the influence of LSD. Would LSD dreams be regarded as literal predictions of reality by anyone today?
