I mean, I don't believe it but bible believers do; how about the global flood? Various plagues in Egypt as well as ending the whole party with killing off all first-born sons? Commending genocide (multiple times)? Enabling chattel slavery? Obliterating Sodom and Gomora(sp?). Ooh, on that same point, didn't he just turn Lot's wife into salt because he looked at her? All the stuff he did to Job to win a bet? And I think Jesus set a wild bear on a bunch of kids because they were bullying some guy?
Those are off the top of my head, but I know there's more.
So which sense do we use to interpret the rules set out on how to get/treat slaves? How is that interpreted? Is it a metaphor? And how do you know which is which?
What it sounds like is you have lots of leeway to account for what you choose to believe is truth or fiction to fit your needs at any given moment. And if you're not sure what, if any, is literally true, how do you know there's a god at all? And you're defending Catholicism, which is in for an even more uphill battle than most because it's been around longer and has to account for all the beliefs that have had to be updated as knowledge and culture had changed.
