The moral argument begins with the fact that all people recognize some moral code (that some things are right, and some things are wrong). Every time we argue over right and wrong, we appeal to a higher law that we assume everyone is aware of, holds to, and is not free to arbitrarily change. Right and wrong imply a higher standard or law, and law requires a lawgiver. Because the Moral Law transcends humanity, this universal law requires a universal lawgiver. This, it is argued, is God. In support of the moral argument, we see that even the most remote tribes who have been cut off from the rest of civilization observe a moral code similar to everyone else’s. Although differences certainly exist in civil matters, virtues like bravery and loyalty and vices like greed and cowardice are universal. If man were responsible for that code, it would differ as much as every other thing that man has invented. Further, it is not simply a record of what mankind does—rarely do people ever live up to their own moral code.
Where, then, do we get these ideas of what should be done? Romans 2:14-15 says that the moral law (or conscience) comes from an ultimate lawgiver above man. If this is true, then we would expect to find exactly what we have observed. This lawgiver is God. Some call this moral prescription “conscience”; others call it “Natural Law”. We refer to it as “The Moral Law.” But whatever you call it, the fact that a moral standard has been prescribed on the minds of all human beings points to a Moral Law Prescriber. Every prescription has a prescriber. The Moral Law is no different. Someone must have given us these moral obligations.
This Moral Law is our third argument for the existence of a theistic God (after the Cosmological and Teleological Arguments). It goes like this:
- Every law has a law giver.
- There is a Moral Law.
- Therefore, there is a Moral Law Giver.
If the first and second premises are true, then the conclusion necessarily follows. Of course, every law has a law giver. There can be no legislation unless there’s a legislature. Moreover, if there are moral obligations, there must be someone to be obligated to. But is it really true that there is a Moral Law? “Nature’s Law” is “self-evident.” You don’t use reason to discover it, you just know it. Without an objective standard of meaning and morality, then life is meaningless and there’s nothing absolutely right or wrong. Everything is merely a matter of opinion. When we say the Moral Law exists, we mean that all people are impressed with a fundamental sense of right and wrong.
Everyone knows, for example, that love is superior to hate and that courage is better than cowardice. University of Texas at Austin professor J. Budziszewski writes, “Everyone knows certain principles. There is no land where murder is virtue and gratitude vice. “We can’t not know, for example, that it is wrong to kill innocent human beings for no reason. Some people may deny it and commit murder anyway, but deep in their hearts they know murder is wrong. Even serial killers know murder is wrong—they just may not feel remorse. And like all absolute moral laws, murder is wrong for everyone, everywhere: in America, India, Zimbabwe, and in every other country, now and forever. That’s what the Moral Law tells every human heart. In other words, everyone knows there are absolute moral obligations. An absolute moral obligation is something that is binding on all people, at all times, in all places. And an absolute Moral Law implies an absolute Moral Law Giver.
