"THE APOSTLE PAUL, "TEACHER OF THE GENTILES in faith and truth" taught the Church which he gathered from the Gentiles how it ought to interpret the books of the Law. These books were received from others and were formerly unknown to the Gentiles and were very strange. He feared that the Church, receiving foreign instructions and not knowing the principle of the instructions, would be in a state of confusion about the foreign document. For that reason, he gives some examples of interpretation that we also might note similar things in other passages, lest we believe that by imitation of the text and document of the Jews we be made disciples. He wishes, therefore, to distinguish disciples of Christ from disciples of the Synagogue by the way they understand the Law. The Jews, by misunderstanding it, rejected Christ. We, by understanding the Law spiritually, show that it was justly given for the instruction of the Church."Origen

"If anyone does not observe the Decalogue (Commandments), he has no salvation."Irenaeus
Against Heresies Bk. 4 Ch. XV, Vol. 1

"For God has given us a law and holy commandments; and everyone who keeps these can be saved, and, obtaining the resurrection, can inherit incorruption."Theophilus
To Autolycus Ch. XXVII, Vol. 2

"Let us then aim at the fulfilment of the commandments by the works of the Lord; for the Word, Himself also, having openly become flesh, (Joh_1:14) exhibited the same virtue, both practical and contemplative. Wherefore let us regard the Word as law, and His commands and counsels as the short and straight paths to immortality; for His precepts are full of persuasion, not of fear."Clement of Alexandria
Instructor Bk. 1 Ch. III, Vol. 2

Moreover, if the law of Moses had contained nothing which was to be understood as hating a secret meaning, the prophet would not have said in his prayer to God, “Open Thou mine eyes, and I will behold wondrous things out of Thy law;” (cf. Psa_119:18) whereas he knew that there was a veil of ignorance lying upon the heart of those who read but do not understand the figurative meaning, which veil is taken away by the gift of God, when He hears him who has done all that he can, and who by reason of habit has his senses exercised to distinguish between good and evil, and who continually utters the prayer, “Open Thou mine eyes, and I will behold wondrous things out of Thy law.”Origen
Against Celsus Bk. 2 Ch. L, Vol. 4

"For when the prophet says, “Open Thou mine eyes, that I may behold wondrous things out of Thy law,” (Psa_119:18) or, “The commandment of the Lord is pure, enlightening the eyes,” (Psa_19:8) or, “Lighten mine eyes, lest I sleep the sleep of death,” (Psa_13:3) no one is so foolish as to suppose that the eyes of the body behold the wonders of the divine law, or that the law of the Lord gives light to the bodily eyes, or that the sleep of death falls on the eyes of the body. When our Savior says, “He that hath ears to hear, let him hear,” (Mat_13:9) anyone will understand that the ears spoken of are of a diviner kind."Origen
Against Celsus Bk. 7 Ch. XXXIV, Vol. 4

"The law of this man who possesses knowledge is the saving precept; or rather, the law is the precept of knowledge. For the Word is “the power and the wisdom of God.” (1Co_1:24) Again, the expounder of the laws is the same one by whom the law was given; the first expounder of the divine commands, who unveiled the bosom of the Father, the only-begotten Son. Then those who obey the law, since they have some knowledge of Him, cannot disbelieve or be ignorant of the truth. But those who disbelieve, and have shown a repugnance to engage in the works of the law, whoever else may, certainly confess their ignorance of the truth."Clement
Stromata Bk. 1 Ch. XXVI, Vol. 2

"Why, then, did the Lord not form the covenant for the fathers? Because “the law was not established for righteous men.” (1Ti_1:9) But the righteous fathers had the meaning of the Decalogue written in their hearts and souls, that is, they loved the God who made them, and did no injury to their neighbor. There was therefore no occasion that they should be cautioned by prohibitory mandates (correptoriis literis), because they had the righteousness of the law in themselves. But when this righteousness and love to God had passed into oblivion, and became extinct in Egypt, God did necessarily, because of His great goodwill to men, reveal Himself by a voice, and led the people with power out of Egypt, in order that man might again become the disciple and follower of God;”"Iranaeus
Against Heresies Bk. 4 Ch. XVI, Vol 1

Love not the world, nor its contents. Such is God’s word, and it seems good to thee. Thou observest man’s command, and shunnest God’s. Thou trustedst to the gift whereby the teachers shut up their mouths, that they may be silent, and not tell thee the divine commands; while I speak the truth, as thou art bound look to the Highest. Assign thyself as a follower to Him whose son thou wast. If thou seekest to live, being a believing man, as do the Gentiles, the joys of the world remove thee from the grace of Christ. With an undisciplined(1) mind thou seekest what thou presumest to be easily lawful, both thy dear actors and their musical strains; nor carest thou that the offspring of such an one should babble follies. While thou thinkest that thou art enjoying life, thou art improvidently erring. The Highest commands, and thou shunnest His righteous precepts.Commodianus

"Let Moses wash you, therefore; let him wash you and let him clothe you. (4) You have heard many times how Moses can wash you. For we often have said that Moses in Holy Scripture stands for the Law, as it was said in the gospel, "They have Moses and the Prophets. Let them hear them.14 Therefore, it is the Law of God which washes you. This cleanses your filthiness. This, if you hear it, removes the stains of your sins. This is Moses, that is, the Law, which consecrates priests. He cannot be a priest whom the Law has not appointed as a priest. For there are many priests but there are those whom the Law has not washed and the Word of God has not made pure and the divine Word has not cleansed from the filthiness of sins."Origen
Homilies on Leviticus, Homily VI

If any one makes light of the law or the prophets, which Christ fulfilled at His coming, let him be to thee as Antichrist.Ignatius (Disciple of Apostle John)
Spurious Epistles Ch. II, Vol. I

"We hold, then, that the law has a twofold sense, - the one literal, the other spiritual, - as has been shown by some before us. Of the first or literal sense it is said, not by us, but by God, speaking in one of the prophets, that “the statutes are not good, and the judgments not good;” (Eze_20:25) whereas, taken in a spiritual sense, the same prophet makes God say that “His statutes are good, and His judgments good.” Yet evidently the prophet is not saying things which are contradictory of each other. Paul in like manner says, that “the letter killeth, and the spirit giveth life,” (2Co_3:6) meaning by “the letter” the literal sense, and by “the spirit” the spiritual sense of Scripture."Origen
Against Celsus Bk. 7 Ch. XX, Vol. 4

"All then are good together, the law, the prophets, the apostles, and the whole company [of others] that have believed through them: only if we love one another."Ignatius (Disciple of Apostle John)
Epistle to the Philippians Ch. IX, Vol. 1

"For he teaches, as I think, that true instruction is desire for knowledge; and the practical exercise of instruction produces love of knowledge. And love is the keeping of the commandments which lead to knowledge. And the keeping of them is the establishment of the commandments, from which immortality results. “And immortality brings us near to God.”"Clement
Exhortation Ch. XV, Vol. 2

"But let it be granted that Jesus observed all the Jewish usages, including even their sacrificial observances, what does that avail to prevent our recognizing Him as the Son of God? Jesus, then, is the Son of God, who gave the law and the prophets; and we, who belong to the Church, do not transgress the law, but have escaped the mythologizing’s of the Jews, and have our minds chastened and educated by the mystical contemplation of the law and the prophets. For the prophets themselves, as not resting the sense of these Words in the plain history which they relate, nor in the legal enactments taken according to the word and letter, express themselves somewhere, when about to relate histories, in words like this, “I will open my mouth in parables, I will utter hard sayings of old;” (Psa_78:2) and in another place, when offering up a prayer regarding the law as being obscure, and needing divine help for its comprehension, they offer up this prayer, “Open Thou mine eyes, that I may behold wondrous things out of Thy law.” (Psa_119:18)"Origen
Against Celsus Bk. 2 Ch. VI, Vol. 4

"And writing to the Galatians, and upbraiding certain individuals who seem to themselves to read the law, and yet without understanding it, because of their ignorance of the fact that an allegorical meaning underlies what is written, he says to them in a certain tone of rebuke: “Tell me, ye who desire to be under the law, do ye not hear the law? For it is written that Abraham had two sons; the one by a bond-maid, the other by a free woman. But he who was of the bond-woman was born according to the flesh; but he of the free woman was by promise. Which things are an allegory: for these are the two covenants.” (Gal_4:21-24)"Origen
De Principiis Bk. 4 Ch. I, Vol. 4

"And Moses understood that they had again made molten images; and he threw the tables out of his hands, and the tables of the testament of the Lord were broken. Moses then received it, but they proved themselves unworthy. Learn now how we have received it. Moses, as a servant, (Comp. Heb_3:5) received it; but the Lord himself, having suffered in our behalf, hath given it to us, that we should be the people of inheritance."Barnabas
Epistle Pt. 2 Ch. XIV, Vol. 1

"He shall come from heaven with glory, when the man of apostasy, who speaks strange things against the Most High, shall venture to do unlawful deeds on the earth against us the Christians, who, having learned the true worship of God from the law, and the word which went forth from Jerusalem by means of the apostles of Jesus"Justin Martyr
Dialogue with Trypho Ch. CX, Vol. 1

Dost thou dissemble with the law that was given with such public announcement, crying out in the heavenly word of so many prophets? If a prophet had only cried out to the clouds, the word of the Lord uttered by him would surely suffice. The law of the Lord proclaims itself into so many volumes of prophets; none of them excuses wickedness; thus even thou wishest from the heart to see good things; thou art also seeking to live by deceits. Why, then, has the law itself gone forth with so much pains? Thou abusest the commands of the Lord, and yet thou callest thyself His son. Thou art seen, if thou wilt be such without reason. I say, the Almighty seeks the meek to be His sons, those who are upright with a good heart, those who are devoted to the divine law; but ye know already where He has plunged the wicked.Commodianus
