The difference between creator and creature is infinite, not just ‘very great’; ‘creator’ does not merely refer to the supreme causal power by which the world is explained, for God would then be simply a ‘principle superior to the world,’ or ‘the biggest thing around.’ Such conceptions falter by making God one term in a relation, and so only comparatively, not absolutely, different.
What is creation? Quite often, when asked that question, everyday Christians immediately direct attention to what has been made. One might say, “Look at the vast sky above, with its moon and stars, its sun and clouds which give rain from heaven.” We might point to the ocean and all its deep mysteries or the Grand Canyon’s majestic scenery. This is not a wrong answer to the question. Theologians of the Christian theological tradition, however, give a more theocentric answer to that question. This is certainly due to the fact that they are theologians. But if we ponder the question a bit more, contemplating how the Bible presents to us the account of creation in Genesis 1, our answer would start with God and go out from there. For example, when defining the doctrine of creation, Herman Bavinck says, “[Creation is] that act of God through which, by his sovereign will, he brought the entire world out of nonbeing into being that is distinct from his own being.” Notice that Bavinck begins his definition in a theocentric manner. Creation is an act of God. Bavinck’s definition is important for it clearly upholds a creator/creature distinction. Creation is of another order of being from divine being. Divine being is; created being is brought into existence by God. There are two orders of being: created being and non-created, or divine, being. The former is finite (i.e., having bounds or limits according to its created capacities); the latter infinite (i.e., having no bounds or limits according to its uncreated essence and is thus incomprehensible to the creature). The former is temporal (i.e., it began-to-be with time and exists in relation to it); the latter eternal (i.e., ever existing, “without beginning or end and apart from all succession and change”). The former is dependent; the latter independent. Creatures are contingent; God is not. As John of Damascus said long ago, “All things are distant from God . . . by nature.” Created nature and divine nature are both distinct and different in kind.
Creation ex nihilo entails that the eternal God, the immutable God, the infinite God, the Father, Son, and Holy Spirit, brought creatures into existence without the use of existing materials. This also means creation brought no change in God, though it came from God. Things which come from God are teeming with change, though there is no change in God in bringing forth that which changes. Bringing things into being distinct from himself makes God the efficient cause of creation. That is, God, and God alone, the triune God, brought creation into existence without any change in God the Trinity. According to Edward Feser, “An efficient cause is that which brings something into existence.”
