I attended theological college in the 1970s- where I was taught that the old testament is unhistorical, the gospels utterly unreliable, the sayings of Jesus plagiarised and the whole Bible (though it wasn't put that way) a crazy patchwork of lies and forgeries. I was then expected to go out and preach from it as if I believed it was the Word of God.
It did my head in.
When I became a witch I made a virtue out of there being no such thing as a Wiccan scripture.
