without really entering godwin-land, I do wonder how people would have reacted if the law was created to not recognize Jewish Law or Christian Law as a result of what is written in the Old/New Testaments.

It would probably cause a lot of pro-life people difficulty to know that the courts don't acknowledge the Christian concept of a soul when determining the legality of abortion and/or birth control, or how religions acknowledge marriage WRT considering the legality of gay marriage.
