It is really more vague news than fake news. Holy books are templates that are easily [re]interpreted for the needs of the moment. Of course there's outright fabrication, such as the fabulist mythos of the gospels. The basis is asserted without evidence. But the details ... there just aren't any really. The Bible says to love one another, whatever that means, for example. People throughout history have owned and mistreated slaves and indentured servants and women and children and foreigners, and were still convinced they were loving "one another" because "one another" was referring to people of a certain social status and standing or level of wealth or of a particular gender or race. It did not include "everyone" because if the Bible had said "love everyone" it would have been far too specific and limiting. "One another" can be taken as "my clique" and fuck everyone else. Or if you prefer it can be assume to mean "everyone" but still with some implicit exclusions, just less extensive ones.

When you think about it, religious notions of morality and ethics can't stray very far from those of the religion's host society, or the religion will be rejected by the host society. So for the Bible or the Quran to have enduring appeal for countless generations it has to be able to be, for lack of a better term, flexibly interpreted so as to be just different enough from the secular society to be appealing but similar enough to be accepted. As such it is full of noble-sounding sentiments upon which people can project their assumptions and hopes and dreams and fears.

Even within the literalist / inerrantist / fundamentalist world I came out of, there is disagreement about a host of specific things that the Bible simply doesn't address and which are just inferred. That is how you can for example have Pentecostals / Charismatics reading the same Bible as other fundamentalists and coming up with boatloads of extra dogma and doctrine and completely conflicting notions about whether the miraculous is to be expected in the modern era or whether personal experience is reliably instructive about the will of god.

Oh, so THAT'S the trinity I hear so much about!

More like fairy tales.
