Everything that applies can be cross-referenced with the commandments that are actually directly dictated by God - meaning the 10 commandments and the 2 greatest commandments given by Jesus. Infant sacrifice I would say counts as murder. Adultery is also forbidden. Bestiality... hmmmm. Well, anything that was called a sin or "against God" was called so for a reason. In my last post in this thread, I explained why (I believe) homosexuality was called a sin in those days. But other sins are sins because they are harmful to yourself or others. Incest is definitely so, because the family has a more important role to play, and incest also results in genetic deformities, etc. But bestiality.... I'm not entirely sure why that would be called a sin, other than it's just weird. I suppose that it would have been called an "abomination" in Leviticus on the man's part for the same reasons homosexuality was named such. For the woman's part, I dunno... perhaps they thought a woman could be impregnated by a cow? Yikes... Am I saying that bestiality should not be considered a sin? I'm not sure, and therefore I don't judge (but I still get weirded out).

Well anyway, I'd say that's the short version of how to sort out what applies to us in Scriptural law, and what doesn't. Hope it makes sense.
