"The natural law is immutable and permanent throughout the variations of history" (CCC#1958) because it is based on God-made essential human nature, which does not change with time or place, rather than man-made cultural developments, which do. However, devout Christians number in the hundreds of millions in the world today and the Protestant and Catholic Churches are significant players in almost every country’s moral discourse.

At some level, law and the goals behind it (justice, equity, fairness, security) do not prove themselves out of thin air. Natural Law presupposes belief in the divine which is not compatible with a less religious fundamentalist society as well as allowing for simple ethical questions to become complicated moral dilemmas. You need to adopt some underlying decisions about what to achieve, and the reasons for doing so. Due to these arguments against it, Natural Law Theory plays virtually no role in contemporary secular moral discourse (Rachels, 2007: 60). Thus, knowledge of Natural Law Theory is necessary to engage with and understand the traditional Christian position.
