Different Degrees of Knowledge
The proof of the truth being with us, is the fact of the Son of God Himself having taught us. For if in every inquiry these universals are found, a person and a subject, that which is truly the truth is shown to be in our hands alone. For the Son of God is the person of the truth which is exhibited; and the subject is the power of faith, which prevails over the opposition of every one whatever, and the assault of the whole world.
But since this is confessedly established by eternal facts and reasons, and each one who thinks that there is no Providence has already been seen to deserve punishment and not contradiction, and is truly an atheist, it is our aim to discover what doing, and in what manner living, we shall reach the knowledge of the sovereign God, and how, honouring the Divinity, we may become authors of our own salvation. Knowing and learning, not from the Sophists, but from God Himself, what is well-pleasing to Him, we endeavour to do what is just and holy. Now it is well-pleasing to Him that we should be saved; and salvation is effected through both well-doing and knowledge, of both of which the Lord is the teacher.
If, then, according to Plato, it is only possible to learn the truth either from God or from the progeny of God, with reason we, selecting testimonies from the divine oracles, boast of learning the truth by the Son of God, prophesied at first, and then explained.
Philosophy and heresies, aids in discovering the truth.
But the things which co-operate in the discovery of truth are not to be rejected. Philosophy, accordingly, which proclaims a Providence, and the recompense of a life of felicity, and the punishment, on the other hand, of a life of misery, teaches theology comprehensively; but it does not preserve accuracy and particular points; for neither respecting the Son of God, nor respecting the economy of Providence, does it treat similarly with us; for it did not know the worship of God.
Wherefore also the heresies of the Barbarian philosophy, although they speak of one God, though they sing the praises of Christ, speak without accuracy, not in accordance with truth; for they discover another God, and receive Christ not as the prophecies deliver. But their false dogmas, while they oppose the conduct that is according to the truth, are against us. For instance, Paul circumcised Timothy because of the Jews who believed, in order that those who had received their training from the law might not revolt from the faith through his breaking such points of the law as were understood more cam ally, knowing right well that circumcision does not justify; for he professed that “all things were for all” by conformity, preserving those of the dogmas that were essential, “that he might gain all.” And Daniel, under the king of the Persians, wore “the chain,” though he despised not the afflictions of the people.
The liars, then, in reality are not those who for the sake of the scheme of salvation conform, nor those who err in minute points, but those who are wrong in essentials, and reject the Lord, and as far as in them lies deprive the Lord of the true teaching; who do not quote or deliver the Scriptures in a manner worthy of God and of the Lord; for the deposit rendered to God, according to the teaching of the Lord by His apostles, is the understanding and the practice of the godly tradition. “And what you hear in the ear”— that is, in a hidden manner, and in a mystery (for such things are figuratively said to be spoken in the ear)— “proclaim,” He says, “on the housetops,” understanding them sublimely, and delivering them in a lofty strain, and according to the canon of the truth explaining the Scriptures; for neither prophecy nor the Saviour Himself announced the divine mysteries simply so as to be easily apprehended by all and sundry, but express them in parables. The apostles accordingly say of the Lord, that “He spoke all things in parables, and without a parable spoke He nothing unto them;” and if “all things were made by Him, and without Him was not anything made that was made,” consequently also prophecy and the law were by Him, and were spoken by Him in parables. “But all things are right,” says the Scripture, “before those who understand,” that is, those who receive and observe, according to the ecclesiastical rule, the exposition of the Scriptures explained by Him; and the ecclesiastical rule is the concord and harmony of the law and the prophets in the covenant delivered at the coming of the Lord. Knowledge is then followed by practical wisdom, and practical wisdom by self-control: for it may be said that practical wisdom is divine knowledge, and exists in those who are deified; but that self-control is mortal, and subsists in those who philosophize, and are not yet wise. But if virtue is divine, so is also the knowledge of it; while self-control is a sort of imperfect wisdom which aspires after wisdom, and exerts itself laboriously, and is not contemplative. As certainly righteousness, being human, is, as being a common thing, subordinate to holiness, which subsists through the divine righteousness; for the righteousness of the perfect man does not rest on civil contracts, or on the prohibition of law, but flows from his own spontaneous action and his love to God.
Reasons for the meaning of Scripture being veiled.
For many reasons, then, the Scriptures hide the sense. First, that we may become inquisitive, and be ever on the watch for the discovery of the words of salvation. Then it was not suitable for all to understand, so that they might not receive harm in consequence of taking in another sense the things declared for salvation by the Holy Spirit. Wherefore the holy mysteries of the prophecies are veiled in the parables— preserved for chosen men, selected to knowledge in consequence of their faith; for the style of the Scriptures is parabolic. Wherefore also the Lord, who was not of the world, came as one who was of the world to men. For He was clothed with all virtue; and it was His aim to lead man, the foster-child of the world, up to the objects of intellect, and to the most essential truths by knowledge, from one world to another.
Wherefore also He employed metaphorical description; for such is the parable—a narration based on some subject which is not the principal subject, but similar to the principal subject, and leading him who understands to what is the true and principal thing; or, as some say, a mode of speech presenting with vigour, by means of other circumstances, what is the principal subject.
And now also the whole economy which prophesied of the Lord appears indeed a parable to those who know not the truth, when one speaks and the rest hear that the Son of God— of Him who made the universe— assumed flesh, and was conceived in the virgin's womb (as His material body was produced), and subsequently, as was the case, suffered and rose again, being “to the Jews a stumbling-block, and to the Greeks foolishness,” as the apostle says.
