CIC 297 Scripture bears witness to faith in creation “out of nothing” as a truth full of promise and hope. Thus the mother of seven sons encourages them for martyrdom:
I do not know how you came into being in my womb. It was not I who gave you life and breath, nor I who set in order the elements within each of you. Therefore the Creator of the world, who shaped the beginning of man and devised the origin of all things, will in his mercy give life and breath back to you again, since you now forget yourselves for the sake of his laws. .. Look at the heaven and the earth and see everything that is in them, and recognize that God did not make them out of things that existed. Thus also mankind comes into being.1
