Somehow I think the Religious Right ignores this part of the Bible.
As it should.
We ignore parts of the Law of Moses that weren't carried into the New Testament. We are under a New Covenant with its own set of laws which include some laws from the Law of Moses and some laws that are written in Genesis PRIOR to the Law of Moses...but ALL our laws DO have a legal precedent in the Old Testament regardless. Some predate the Law of Moses (we have Noah's diet, not the diet of the Jews) and some of our laws are retained from the Law of Moses (no sexual relations with close relatives).
The New Covenant superseded the Law of Moses.
