Genesis 2:3

18. Nevertheless the seventh day was appointed to the Jewish nation as a day to be observed by rest of the body, that it might be a type of sanctification to which men attain through rest in the Holy Spirit. We do not read of sanctification in the history given in Genesis of all the earlier days: of the Sabbath alone it is said that “God blessed the seventh day, and sanctified it.” Now the souls of men, whether good or bad, love rest, but how to attain to that which they love is to the greater part unknown: and that which bodies seek for their weight, is precisely what souls seek for their love, namely, a resting-place. …

The soul, then, shall have an intellectual remembrance of its past ills; but, so far as regards sensible experience, they shall be quite forgotten. For a skillful physician knows, indeed, professionally almost all diseases; but experimentally he is ignorant of a great number which he himself has never suffered from. As, therefore, there are two ways of knowing evil things, one by mental insight, the other by sensible experience, for it is one thing to understand all vices by the wisdom of a cultivated mind, another to understand them by the foolishness of an abandoned life, so also there are two ways of forgetting evils. For a well-instructed and learned man forgets them one way, and he who has experimentally suffered from them forgets them another, the former by neglecting what he has learned, the latter by escaping what he has suffered. …

28. “Now, on the subject of this rest Scripture is significant, and refrains not to speak, when it tells us how at the beginning of the world, and at the time when God made heaven and earth and all things which are in them, He worked during six days, and rested on the seventh day. For it was in the power of the Almighty to make all things even in one moment of time. For He had not labored in the view that He might enjoy (a needful) rest, since indeed “He spake, and they were made; He commanded, and they were created;” but that He might signify how, after six ages of this world, in a seventh age, as on the seventh day, He will rest in His saints; inasmuch as these same saints shall rest also in Him after all the good works in which they have served Him, which He Himself, indeed, works in them, who calls them, and instructs them, and puts away the offenses that are past, and justifies the …

1. …It is entitled, “The Song of praise of David himself, on the day before the Sabbath, when the earth was founded.” Remembering then what God did through all those days, when He made and ordained all things, from the first up to the sixth day (for the seventh He sanctified, because He rested on that day after all the works, which He made very good), we find that He created on the sixth day (which day is here mentioned, in that he saith, “before the Sabbath”) all animals on the earth; lastly, He on that very day created man in His own likeness and image. For these days were not without reason ordained in such order, but for that ages also were to run in a like course, before we rest in God. But then we rest if we do good works. As a type of this, it is written of God, “God rested on the seventh day,” when He had made all His works very good. …

57. For had He been a creature, He had not said, ‘He begets me,’ for the creatures are from without, and are works of the Maker; but the Offspring is not from without nor a work, but from the Father, and proper to His Essence. Wherefore they are creatures; this God’s Word and Only-begotten Son. For instance, Moses did not say of the creation, ‘In the beginning He begat,’ nor ‘In the beginning was,’ but ‘In the beginning God created the heaven and the earth.’ Nor did David say in the Psalm, ‘Thy hands have “begotten me,”’ but ‘made me and fashioned me,’ everywhere applying the word ‘made’ to the creatures. …
