Aquinas tried to establish his metaphysics of creation theologically and philosophically. Crea- ting belongs to God alone, as means that it is God＇s divine action. For God, as to its essence, is nothing but pure act. The essence of creation is creatio ex nihilo, as means that God the Creator alone creates the entire world out of nothing.

Although all the things come from God absolutely, they have their own participated being and good. As a new theological paradigm, Aquinas＂ metaphysics of creation was a philosophical ex- pression of the Bible sentence, namely, ＂In the beginning God creates heaven and earth. ＂
