Abstract
As Augustine finished the Confessions, he started thinking about two topics which were to occupy him over many years: the exegesis of the first three chapters of Genesis and the doctrine of the Trinity. ‘Creating and the Trinity’ describes his thinking in these two areas. The idea of an instantaneous act of creation suggested something magical. Rather, the world was a developing process. Augustine was confident in the rationality of the universe. Quirks of free choice introduce irrationalities. As for the Trinity, Augustine explained the concept of being one and three as a triad of being, knowing, and willing. He saw the terms Father and Son to be words expressing relation, not substance.
