That the World Took Its Beginning in Time
1 And now, since there is one of the articles of the Church which is held principally in consequence of our belief in the truth of our sacred history, viz. that this world was created and took its beginning at a certain time, and, in conformity to the cycle of time decreed to all things, is to be destroyed on account of its corruption, there seems no absurdity in re-discussing a few points connected with this subject. And so far, indeed, as the credibility of Scripture is concerned, the declarations on such a matter seem easy of proof. Even the heretics, although widely opposed on many other things, yet on this appear to be at one, yielding to the authority of Scripture.
Concerning, then, the creation of the world, what portion of Scripture can give us more information regarding it, than the account which Moses has transmitted respecting its origin? And although it comprehends matters of profounder significance than the mere historical narrative appears to indicate, and contains very many things that are to be spiritually understood, and employs the letter, as a kind of veil, in treating of profound and mystical subjects; nevertheless the language of the narrator shows that all visible things were created at a certain time. But with regard to the consummation of the world, Jacob is the first who gives any information, in addressing his children in the words: “Gather yourselves together unto me, you sons of Jacob, that I may tell you what shall be in the last days,” or “after the last days.” If, then, there be “last days,” or a period “succeeding the last days,” the days which had a beginning must necessarily come to an end. David, too, declares: “The heavens shall perish, but You shall endure; yea, all of them shall wax old as does a garment: as a vesture shall You change them, and they shall be changed: but You are the same, and Your years shall have no end.” Our Lord and Saviour, indeed, in the words, “He who made them at the beginning, made them male and female,” Himself bears witness that the world was created; and again, when He says, “Heaven and earth shall pass away, but My word shall not pass away,” He points out that they are perishable, and must come to an end. The apostle, moreover, in declaring that “the creature was made subject to vanity, not willingly, but by reason of Him who has subjected the same in hope, because the creature itself also shall be delivered from the bondage of corruption into the glorious liberty of the children of God,” manifestly announces the end of the world; as he does also when he again says, “The fashion of this world passes away.” Now, by the expression which he employs, “that the creature was made subject to vanity,” he shows that there was a beginning to this world: for if the creature were made subject to vanity on account of some hope, it was certainly made subject from a cause; and seeing it was from a cause, it must necessarily have had a beginning: for, without some beginning, the creature could not be subject to vanity, nor could that (creature) hope to be freed from the bondage of corruption, which had not begun to serve. But any one who chooses to search at his leisure, will find numerous other passages in holy Scripture in which the world is both said to have a beginning and to hope for an end.
2. Now, if there be any one who would here oppose either the authority or credibility of our Scriptures, we would ask of him whether he asserts that God can, or cannot, comprehend all things? To assert that He cannot, would manifestly be an act of impiety. If then he answer, as he must, that God comprehends all things, it follows from the very fact of their being capable of comprehension, that they are understood to have a beginning and an end, seeing that which is altogether without any beginning cannot be at all comprehended. For however far understanding may extend, so far is the faculty of comprehending illimitably withdrawn and removed when there is held to be no beginning.
3. But this is the objection which they generally raise: they say, “If the world had its beginning in time, what was God doing before the world began? For it is at once impious and absurd to say that the nature of God is inactive and immoveable, or to suppose that goodness at one time did not do good, and omnipotence at one time did not exercise its power.” Such is the objection which they are accustomed to make to our statement that this world had its beginning at a certain time, and that, agreeably to our belief in Scripture, we can calculate the years of its past duration. To these propositions I consider that none of the heretics can easily return an answer that will be in conformity with the nature of their opinions. But we can give a logical answer in accordance with the standard of religion, when we say that not then for the first time did God begin to work when He made this visible world; but as, after its destruction, there will be another world, so also we believe that others existed before the present came into being. And both of these positions will be confirmed by the authority of holy Scripture. For that there will be another world after this, is taught by Isaiah, who says, “There will be new heavens, and a new earth, which I shall make to abide in my sight, says the Lord;” and that before this world others also existed is shown by Eccelesiastes, in the words: “What is that which has been? Even that which shall be. And what is that which has been created? Even this which is to be created: and there is nothing altogether new under the sun. Who shall speak and declare, Lo, this is new? It has already been in the ages which have been before us.” By these testimonies it is established both that there were ages before our own, and that there will be others after it. It is not, however, to be supposed that several worlds existed at once, but that, after the end of this present world, others will take their beginning; respecting which it is unnecessary to repeat each particular statement, seeing we have already done so in the preceding pages.
