5. And God called the light That is, God willed that there should be a regular vicissitude of days and nights; which also followed immediately when the first day was ended. For God removed the light from view, that night might be the commencement of another day. What Moses says however, admits a double interpretation; either that this was the evening and morning belonging to the first day, or that the first day consisted of the evening and the morning. Whichever interpretation be chosen, it makes no difference in the sense, for he simply understands the day to have been made up of two parts. Further, he begins the day, according to the custom of his nation, with the evening. It is to no purpose to dispute whether this be the best and the legitimate order or not. We know that darkness preceded time itself; when God withdrew the light, he closed the day. I do not doubt that the most ancient fathers, to whom the coming night was the end of one day and the beginning of another, followed this mode of reckoning. Although Moses did not intend here to prescribe a rule which it would be criminal to violate; yet (as we have now said) he accommodated his discourse to the received custom. Wherefore, as the Jews foolishly condemn all the reckonings of other people, as if God had sanctioned this alone; so again are they equally foolish who contend that this modest reckoning, which Moses approves, is preposterous.
The first day Here the error of those is manifestly refuted, who maintain that the world was made in a moment. For it is too violent a cavil to contend that Moses distributes the work which God perfected at once into six days, for the mere purpose of conveying instruction. Let us rather conclude that God himself took the space of six days, for the purpose of accommodating his works to the capacity of men. We slightingly pass over the infinite glory of God, which here shines forth; whence arises this but from our excessive dullness in considering his greatness? In the meantime, the vanity of our minds carries us away elsewhere. For the correction of this fault, God applied the most suitable remedy when he distributed the creation of the world into successive portions, that he might fix our attention, and compel us, as if he had laid his hand upon us, to pause and to reflect. For the confirmation of the gloss above alluded to, a passage from Ecclesiasticus is unskilfully cited. ‘He who liveth for ever created all things at once,’ (Genesis 18:1.) For the Greek adverb κοινὣ which the writer uses, means no such thing, nor does it refer to time, but to all things universally. (57)
(57) So the English translation: “He that liveth forever made all things in general.”
