Creation
Creation ex nihilo, conservation and providence
Creation ex nihilo means more than that the world had a beginning. It means that the whole being of every creature is received. God does not fashion the universe from an independent substance, and He does not lose anything of Himself by creating. The creature is genuinely other than God, while depending upon Him more intimately than an artefact depends upon its maker. Conservation is the continuing communication of being; providence is the wise ordering of created causes toward their ends.
This dependence does not make secondary causes unreal. Stones, plants, animals, human choices and historical institutions act according to their natures. Divine causality is not one cause competing inside the universe, but the transcendent cause by which created causes exist and act. The doctrine therefore grounds both scientific inquiry and prayer: nature has stable intelligibility, yet no created order is closed against the Lord who gives it being.
