Yes, there's potential for rules to be changed. That's especially true after Jesus, with the whole "new covenant" thing going on. But in the case of incest, it the change marked by a clear command1.
"Don't judge" doesn't mean "nothing is a sin," so I don't see how it applies. Remember, in the popular "Let he who is without sin cast the first stone" scene, Jesus told the woman, "Go and sin no more."
Similarly, I don't see how "love your neighbor" can be construed to mean, "Excuse your neighbor's sin."
If you want to argue for a NT acceptance of homosexuality, you need different arguments.
1 I also wouldn't say it's fair to call it a "flip flop." We're not talking about random changes, we're talking about a very special case with specific reason for the difference in rules. When starting with two people, incest is a necessity for the first generation or two. Presumably, God could prevent any bad recessive genes from being an issue for that short time. |
