Natural Law

From apologist Jimmy Akin:
"One part of the eternal law is what theologians refer to as the natural law. In the sciences, the phrase natural law is often used to refer to those principles pertaining to non-living or non-intelligent things in the universe. This isn’t the case in theology. In theology, the term is used to refer to those moral precepts of the eternal law that a rational creature can discern without special revelation. For example, the fact that murder, theft, and lying are wrong can be discerned by human reason without special revelation and so the prohibitions against them constitute part of the natural law."

Jimmy gets into an interesting point about how Christians may sometimes feel that they should not be bound by some aspect of natural law that they see in the Old Law of the Mosaic Covenant. They may believe that as they are not under the Old Law as a Christian, that they should not be subject to this or that tenet - not realizing that some of the Old Law (like all of the 10 Commandments) are also part of the Eternal Law known as natural law - even if it was also spelled out in the Old Law.
