If God, Jesus, the devil, angels, and demons were all real, we still couldn’t rely on the Christian Bible as gospal (pun intended) — it was written by humans, specifically men, who could have misunderstood or invented things. Think of it like the Snyderverse in Man of Steel: Superman is portrayed as a brooding, violent character — but that’s not his true nature. In Batman v Superman, Batman is straight-up killing people — also not his normal characterization.
So even if much of the Bible reflects real events or real beings, parts of it could still be distorted, exaggerated, or entirely made up by the people who wrote it down.
Even the Bible has been slightly altered by man though. For instance, a few of the books written in Paul’s name we know now were actually written by some of people under him from within the early church.
So the sections written about women not holding authority within the church may have been put in there to centralize power and make the church have a patriarchal structure.
There’s also the different translations of the Bible which can affect the meaning for some of the text. For instance the Adam and Eve story. Adam means earth in Hebrew, it was not a name. So the person we know as Adam, was created male and then personally chose to identify as male, rather than being given his gender by God. The same for Eve as well being the first woman, although IIRC Eve was her name. Still she chose to identity as the first woman.
Yeah, and there are a bunch of different translations. I know Catholics and Orthodox Christians also include different books in the Bible. I do think it’s possible to view it as a living document. What is included/how it is translated is what is needed at the time.
