On Knowledge and Wisdom
XII, 14. For knowledge also has its own good measure, if that in it which puffs up, or is wont to puff up, is conquered by love of eternal things, which does not puff up, but, as we know, edifies. Certainly without knowledge the virtues themselves, by which one lives rightly, cannot be possessed, by which this miserable life may be so governed, that we may attain to that eternal life which is truly blessed.
22. Yet action, by which we use temporal things well, differs from contemplation of eternal things; and the latter is reckoned to wisdom, the former to knowledge. For although that which is wisdom can also be called knowledge, as the apostle too speaks, where he says, “Now I know in part, but then shall I know even as also I am known;” when doubtless he meant his words to be understood of the knowledge of the contemplation of God, which will be the highest reward of the saints; yet where he says, “For to one is given by the Spirit the word of wisdom, to another the word of knowledge by the same Spirit,” certainly he distinguishes without doubt these two things, although he does not there explain the difference, nor in what way one may be discerned from the other.
But having examined a great number of passages from the Holy Scriptures, I find it written in the Book of Job, that holy man being the speaker, “Behold, piety, that is wisdom; but to depart from evil is knowledge.” In thus distinguishing, it must be understood that wisdom belongs to contemplation, knowledge to action. For in this place he meant by piety the worship of God, which in Greek is called θεοσέβεια.
For the sentence in the Greek mss. has that word. And what is there in eternal things more excellent than God, of whom alone the nature is unchangeable? And what is the worship of Him except the love of Him, by which we now desire to see Him, and we believe and hope that we shall see Him; and in proportion as we make progress, see now through a glass in an enigma, but then in clearness? For this is what the Apostle Paul means by “face to face.”
This is also what John says, “Beloved, now we are the sons of God, and it does not yet appear what we shall be; but we know that, when He shall appear, we shall be like Him; for we shall see Him as He is.” Discourse about these and the like subjects seems to me to be the discourse itself of wisdom. But to depart from evil, which Job says is knowledge, is without doubt of temporal things. Since it is in reference to time [and this world] that we are in evil, from which we ought to abstain that we may come to those good eternal things.
And therefore, whatsoever we do prudently, boldly, temperately, and justly, belongs to that knowledge or discipline wherewith our action is conversant in avoiding evil and desiring good; and so also, whatsoever we gather by the knowledge that comes from inquiry, in the way of examples either to be guarded against or to be imitated, and in the way of necessary proofs respecting any subject, accommodated to our use. […]
XIII, 19. 24. And all these things which the Word made flesh did and bare for us in time and place, belong, according to the distinction which we have undertaken to demonstrate, to knowledge, not to wisdom. And as the Word is without time and without place, it is co-eternal with the Father, and in its wholeness everywhere; and if any one can, and as much as he can, speak truly concerning this Word, then his discourse will pertain to wisdom. And hence the Word made flesh, which is Christ Jesus, has the treasures both of wisdom and of knowledge. For the apostle, writing to the Colossians, says: For I would that you knew what great conflict I have for you, and for them at Laodicea, and for as many as have not seen my face in the flesh; that their hearts might be comforted, being knit together in love, and unto all riches of the full assurance of understanding, to the acknowledgment of the mystery of God which is Christ Jesus: in whom are hid all the treasures of wisdom and knowledge. To what extent the apostle knew all those treasures, how much of them he had penetrated, and in them to how great things he had reached, who can know? Yet, for my part, according to that which is written, But the manifestation of the Spirit is given to every man to profit withal; for to one is given by the Spirit the word of wisdom, to another the word of knowledge by the same Spirit; if these two are in such way to be distinguished from each other, that wisdom is to be assigned to divine things, knowledge to human, I acknowledge both in Christ, and so with me do all His faithful ones. And when I read, The Word was made flesh, and dwelt among us, I understand by the Word the true Son of God, I acknowledge in the flesh the true Son of man, and both together joined into one Person of God and man, by an ineffable copiousness of grace. And on account of this, the apostle goes on to say, And we beheld His glory, the glory as of the Only-begotten of the Father, full of grace and truth. If we refer grace to knowledge, and truth to wisdom, I think we shall not swerve from that distinction between these two things which we have commended. For in those things that have their origin in time, this is the highest grace, that man is joined with God in unity of person; but in things eternal the highest truth is rightly attributed to the Word of God. But that the same is Himself the Only-begotten of the Father, full of grace and truth—this took place, in order that He Himself in things done for us in time should be the same for whom we are cleansed by the same faith, that we may contemplate Him steadfastly in things eternal. And those distinguished philosophers of the heathen who have been able to understand and discern the invisible things of God by those things which are made, have yet, as is said of them, held down the truth in iniquity; because they philosophized without a Mediator, that is, without the man Christ, whom they neither believed to be about to come at the word of the prophets, nor to have come at that of the apostles. For, placed as they were in these lowest things, they could not but seek some media through which they might attain to those lofty things which they had understood; and so they fell upon deceitful spirits, through whom it came to pass, that they changed the glory of the incorruptible God into an image made like to corruptible man, and to birds, and four-footed beasts, and creeping things. For in such forms also they set up or worshipped idols. Therefore Christ is our knowledge, and the same Christ is also our wisdom. He Himself implants in us faith concerning temporal things, He Himself shows forth the truth concerning eternal things. Through Him we reach on to Himself: we stretch through knowledge to wisdom; yet we do not withdraw from one and the same Christ, in whom are hidden all the treasures of wisdom and of knowledge. But now we speak of knowledge, and will hereafter speak of wisdom as much as He Himself shall grant. And let us not so take these two things, as if it were not allowable to speak either of the wisdom which is in human things, or of the knowledge which is in divine. For after a laxer custom of speech, both can be called wisdom, and both knowledge. Yet the apostle could not in any way have written, To one is given the word of wisdom, to another the word of knowledge, except also these several things had been properly called by the several names, of the distinction between which we are now treating.
