That’s what they taught us in Catholic school as a kid. The Old Testament was a combination of parables and oral history before eventually being recorded. Moreover, we were taught that part of the significance of the Crucifixion was that it was to establish a new pact between humans and God, hence Jesus doing away with the old rules and commandments and Jesus commanding that the faith be spread beyond ethnic Jews.

Yup. I’m not catholic anymore but it’s what I was taught too.

That's very sad, but not so surprising, that Catholic schools would teach things that the Catholic Church has never taught. That's usually one more brick in the wall for kids who leave the faith, because their illusions are shattered by teachers and clergy who don't really believe in Church doctrines, and couldn't be bothered to pass down the Truth to children who are eager to know it.

What are you going on about? That’s all nonsense.
