Colossians 2:8

This, then, “the wisdom of the world is foolishness with God,” and of those who are “the wise the Lord knoweth their thoughts that they are vain.” Let no man therefore glory on account of pre-eminence in human thought. For it is written well in Jeremiah, “Let not the wise man glory in his wisdom, and let not the mighty man glory in his might, and let not the rich man glory in his riches: but let him that glorieth glory in this, that he understandeth and knoweth that I am the Lord , that executeth mercy and judgment and righteousness upon the earth: for in these things is my delight, saith the Lord .” “That we should trust not in ourselves, but in God who raiseth the dead,” says the apostle, “who delivered us from so great a death, that our faith should not stand in the wisdom of men, but in the power of God.” “For the spiritual man judgeth all things, but he himself is judged of no man.” …

The Stoics also, whom he mentions too, say not well that the Deity, being a body, pervades the vilest matter. He calls the jugglery of logic “the tradition of men.” Wherefore also he adds, “Avoid juvenile questions. For such contentions are puerile.” “But virtue is no lover of boys,” says the philosopher Plato. And our struggle, according to Gorgias Leontinus, requires two virtues, boldness and wisdom, boldness to undergo danger, and wisdom to understand the enigma. For the Word, like the Olympian proclamation, calls him who is willing, and crowns him who is able to continue unmoved as far as the truth is concerned. And, in truth, the Word does not wish him who has believed to be idle. For He says, “Seek, and ye shall find.” But seeking ends in finding, driving out the empty trifling, and approving of the contemplation which confirms our faith. …

For Paul too, in the Epistles, plainly does not disparage philosophy; but deems it unworthy of the man who has attained to the elevation of the Gnostic, any more to go back to the Hellenic “philosophy,” figuratively calling it “the rudiments of this world,” as being most rudimentary, and a preparatory training for the truth. Wherefore also, writing to the Hebrews, who were declining again from faith to the law, he says, “Have ye not need again of one to teach you which are the first principles of the oracles of God, and are become such as have need of milk, and not of strong meat?” So also to the Colossians, who were Greek converts, “Beware lest any man spoil you by philosophy and vain deceit, after the tradition of men, after the rudiments of this world, and not after Christ,”, enticing them again to return to philosophy, the elementary doctrine.

Through the knowledge, then, as appears, of a bad and good life is the Gnostic saved, understanding and executing “more than the scribes and Pharisees.” “Exert thyself, and prosper, and reign” writes David, “because of truth, and meekness, and righteousness; and thy right hand shall guide thee marvellously,” that is, the Lord. “Who then is the wise? and he shall understand these things. Prudent? and he shall know them. For the ways of the Lord are right,” says the prophet, showing that the Gnostic alone is able to understand and explain the things spoken by the Spirit obscurely. “And he who understands in that time shall hold his peace,” says the Scripture, plainly in the way of declaring them to the unworthy. For the Lord says, “He that hath ears to hear, let him hear,” declaring that hearing and understanding belong not to all. …

Would to God that no “heresies had been ever necessary, in order that they which are approved may be made manifest!” We should then be never required to try our strength in contests about the soul with philosophers, those patriarchs of heretics, as they may be fairly called. The apostle, so far back as his own time, foresaw, indeed, that philosophy would do violent injury to the truth. This admonition about false philosophy he was induced to offer after he had been at Athens, had become acquainted with that loquacious city, and had there had a taste of its huckstering wiseacres and talkers. In like manner is the treatment of the soul according to the sophistical doctrines of men which “mix their wine with water.” Some of them deny the immortality of the soul; others affirm that it is immortal, and something more. …

I am accustomed in my prescription against all heresies, to fix my compendious criterion (of truth) in the testimony of time ; claiming priority therein as our rule, and alleging lateness to be the characteristic of every heresy. This shall now be proved even by the apostle, when he says: “For the hope which is laid up for you in heaven, whereof ye heard before in the word of the truth of the gospel; which is come unto you, as it is unto all the world.” For if, even at that time, the tradition of the gospel had spread everywhere, how much more now! Now, if it is our gospel which has spread everywhere, rather than any heretical gospel, much less Marcion’s, which only dates from the reign of Antoninus, then ours will be the gospel of the apostles. But should Marcion’s gospel succeed in filling the whole world, it would not even in that case be entitled to the character of apostolic. …

Finally, hear Paul as he speaks boldly, and mark how clearly he discovers these: “Beware of evil workers, beware of the concision. Beware lest any man spoil you through philosophy and vain deceit. See that ye walk circumspectly, because the days are evil.” In fine then, what man shall have any excuse who hears these things in the Church from prophets and apostles, and from the Lord Himself, and yet will give no heed to the care of his soul, and to the time of the consummation, and to that approaching hour when we shall have to stand at the judgment-seat of Christ?>

16. The principle of the philosophers and stoics is different, dearest brother, who say that all sins are equal, and that a grave man ought not easily to be moved. But there is a wide difference between Christians and philosophers. And when the apostle says, “Beware, lest any man spoil you through philosophy and vain deceit,” we are to avoid those things which do not come from God’s clemency, but are begotten of the presumption of a too rigid philosophy. …

2. Philosophers also profess that they pursue this virtue; but in their case the patience is as false as their wisdom also is. For whence can he be either wise or patient, who has neither known the wisdom nor the patience of God? since He Himself warns us, and says of those who seem to themselves to be wise in this world, “I will destroy the wisdom of the wise, and I will reprove the understanding of the prudent.” Moreover, the blessed Apostle Paul, filled with the Holy Spirit, and sent forth for the calling and training of the heathen, bears witness and instructs us, saying, “See that no man despoil you through philosophy and vain deceit, after the tradition of men, after the elements of the world, and not after Christ, because in Him dwelleth all the fulness of divinity.” And in another place he says: “Let no man deceive himself; if any man among you thinketh himself to be wise, let hi …

35. These things, moreover, he has said with the view of showing us that all others who may come after him will be false apostles, deceitful workers, transforming themselves into the apostles of Christ. And no marvel; for Satan himself is transformed, like an angel of light. What great thing therefore is it, if his ministers also be transformed into the ministers of righteousness? whose end shall be according to their works. He indicates, further, what manner of men these were, and points out by whom they were being circumvented. And when the Galatians are minded to turn away from the Gospel, he says to them: “I marvel that ye are so soon removed from Him that called you unto another gospel: which is not another; but there be some that trouble you, and would turn you away from the Gospel of Christ. …

8. How ardent was I then, my God, how ardent to fly from earthly things to Thee! Nor did I know how Thou wouldst deal with me. For with Thee is wisdom. In Greek the love of wisdom is called “philosophy,” with which that book inflamed me. There be some who seduce through philosophy, under a great, and alluring, and honourable name colouring and adorning their own errors. And almost all who in that and former times were such, are in that book censured and pointed out. …

3. To Simplicianus then I went, the father of Ambrose (at that time a bishop) in receiving Thy grace, and whom he truly loved as a father. To him I narrated the windings of my error. But when I mentioned to him that I had read certain books of the Platonists, which Victorinus, sometime Professor of Rhetoric at Rome (who died a Christian, as I had been told), had translated into Latin, he congratulated me that I had not fallen upon the writings of other philosophers, which were full of fallacies and deceit, “after the rudiments of the world,” whereas they, in many ways, led to the belief in God and His word. Then, to exhort me to the humility of Christ, hidden from the wise, and revealed to little ones, he spoke of Victorinus himself, whom, whilst he was at Rome, he had known very intimately; and of him he related that about which I will not be silent. …
