Natural Law Needs Revelation

Natural law theory teaches that God embedded a teleological moral order in the world, such that things mature toward fixed ends. Human beings exist to realize both natural and supernatural ends, and, being rational creatures, we’re obligated to discern and pursue goods that fulfill ourselves as the creatures we are. There are moral truths we can’t not know, so we can tease out principles and precepts that prescribe actions to guide us toward our proper ends and prohibit actions that don’t.
