“Creation” therefore means: to make from nothing, to call into existence, that is, to form a being from nothing. Biblical language gives us a glimpse of this significance in the opening words of the Book of Genesis: “In the beginning God created the heavens and the earth.” The word “created” is a translation of the Hebrew bara, which describes an action of extraordinary power whose subject is God alone. Reflection after the exile resulted in a better understanding of the significance of the initial divine intervention. The Second Book of Maccabees finally presents it as a production “not out of things that existed” (7:28). The Fathers of the Church and theologians further clarified the meaning of the divine action by speaking of creation “from nothing” (Creatio ex nihilo; more precisely ex nihilo sui et subjecti).
