Eusebius of Caesarea

“In the beginning you, O Lord, laid the foundation of the earth, and the heavens are the works of your hands,” said the psalmist. If you did not know from the beginning, O Lord, who laid the foundation of the earth, and if the heavens were not the work of your hands, it would be impossible for them to be changed or to be transformed into anything else. If they had not been created, they would have to remain incomplete forever. But since you were their maker, you can do whatever you want to with them. They are made of destructible matter and did not exist at all until you made them by your will and power. There is only one that is eternal and can never be removed and that is you, the only maker of everything that exists.
