Exodus 20:2

Again, when He speaks in His own person, He confesses Himself to be the Instructor: “I am the Lord thy God, who brought thee out of the land of Egypt.” Who, then, has the power of leading in and out? Is it not the Instructor? This was He who appeared to Abraham, and said to him, “I am thy God, be accepted before Me;” and in a way most befitting an instructor, forms him into a faithful child, saying, “And be blameless; and I will make My covenant between Me and thee, and thy seed.” There is the communication of the Instructor’s friendship. And He most manifestly appears as Jacob’s instructor. He says accordingly to him, “Lo, I am with thee, to keep thee in all the way in which thou shalt go; and I will bring thee back into this land: for I will not leave thee till I do what I have told thee.” He is said, too, to have wrestled with Him. …

The first commandment of the Decalogue shows that there is one only Sovereign God; who led the people from the land of Egypt through the desert to their fatherland; that they might apprehend His power, as they were able, by means of the divine works, and withdraw from the idolatry of created things, putting all their hope in the true God.

But not yet about the good to be got from martyrdom must we learn, without our having first heard about the duty of suffering it; nor must we learn the usefulness of it, before we have heard about the necessity for it. The (question of the) divine warrant goes first, whether God has willed and also commanded ought of the kind, so that they who assert that it is not good are not plied with arguments for thinking it profitable save when they have been subdued. It is proper that heretics be driven to duty, not enticed. Obstinacy must be conquered, not coaxed. And, certainly, that will be pronounced beforehand quite good enough, which will be shown to have been instituted and also enjoined by God. …

22. It is also for this reason, that of all the ten commandments, that which related to the Sabbath was the only one in which the thing commanded was typical; the bodily rest enjoined being a type which we have received as a means of our instruction, but not as a duty binding also upon us. For while in the Sabbath a figure is presented of the spiritual rest, of which it is said in the Psalm, “Be still, and know that I am God,” and unto which men are invited by the Lord Himself in the words, “Come unto Me, all ye that labour and are heavy laden, and I will give you rest. Take My yoke upon you, and learn of Me; for I am meek and lowly in heart: so shall ye find rest unto your souls;” as to all the things enjoined in the other commandments, we are to yield to them an obedience in which there is nothing typical. …

11. Call ye to mind from whence he came to this: “one He humbleth, and another He exalteth.” That which was figured to us in the Gospel through two men, a Pharisee and a Publican, this let us, taking in a wider sense, understand of two peoples, of Jews and of Gentiles: the people of the Jews that Pharisee was, the people of the Gentiles that Publican.…As those by being proud have withdrawn, so these by confessing have drawn near. The cup therefore full of pure wine in the hand of the Lord, as far as the Lord giveth me to understand,…the cup of pure wine full of the mixed, seemeth to me to be the Law, which was given to the Jews, and all that Scripture of the Old Testament, as it is called; there are the weights of all manner of sentences. For therein the New Testament lieth concealed, as though in the dreg of corporal Sacraments. …

We have, then, adequately demonstrated that there is a God, and that His essence is incomprehensible. But that God is one and not many is no matter of doubt to those who believe in the Holy Scriptures. For the Lord says in the beginning of the Law: I am the Lord thy God, which have brought thee out of the land of Egypt. Thou shalt have no other Gods before Me . And again He says, Hear, O Israel, the Lord our God is one Lord . And in Isaiah the prophet we read, For I am the first God and I am the last, and beside Me there is no God. Before Me there was not any God, nor after Me will there be any God, and beside Me there is no God . And the Lord, too, in the holy gospels speaketh these words to His Father, And this is life eternal, that they may know Thee the only true God . But with those that do not believe in the Holy Scriptures we will reason thus.

120. I set aside other heretical, not persons, but portents. What manner of judgment awaits them, what shall be the form of their sentence? To all these He will, indeed, reply, rather in sorrow than in anger: “O My people, what have I done unto thee, wherein have I vexed thee? Did I not bring thee up out of Egypt, and lead thee out of the house of bondage into liberty?”

11. And furthermore the Prophet Hosea also said: Light you a lamp and seek ye the Lord . And our Lord Jesus Christ said: What woman is there who has ten drachmos and shall lose one of them, and will not light a lamp and sweep the house and seek her drachma that she lost ? What then does this woman signify? Clearly the congregation of the house of Israel, to which the ten commandments were given. They lost the first commandment, that in which He warned them saying: I am the Lord your God, Who brought you up from the land of Egypt. And when they had lost this first commandment, also the nine which are after it they could not keep, because on the first depend the nine. For it was an impossibility that while worshipping Baal, they should keep the nine commandments. For they lost the first commandment, like that woman who lost one drachma from the ten. …
