Hm, why not? How would you explain some of the more salacious aspects, so to speak?
I mean, I guess there is a basic way to explain it. I knew about the woman being stoned for adultery and I kind of knew what adultery was, but I didn't look too in-depth into the Bible at a young age.
I knew as a kid that Noah had sex with his son, Lot had sex with his daughters. David killed a man to have his wife. David doubled up on the foreskins to present Saul as a prize for his daughter. Solomon . . .
Pretty graphic that scene.
Hey and God kills infants en masse for the decision, wait not really a decision, because God hardened the heart of one man.
Pretty much everything in the Bible was quite clear. But I didn't go to a "Sunday School" church. We read the Bible. And we weren't Puritans. Weird as crazy as it was, the one thing we weren't wasn't Puritanical nor prudish.
EDIT: But I think people were open about this because it wasn't far from most folks' home lives. //:=)
