One reads also that God ordered the sons of Israel to spoil (g) the Egyptians of their gold and silver; the moral interpretation of this teaches that should we find in the poets either the gold of wisdom or the silver of eloquence, we should turn it to the profit of useful learning. In Leviticus also we are ordered to ...
(d) Such a one is rejected by the evidence, as VI. quaest. I. qui crimen. Also, he cannot be a bishop. As XLVIII. dist. § necesse. Nay he is called a dog rather than a bishop. As II. quaest. VII. qui nee. John.
(e) Because he read them for pleasure not for instruction, as de conse. dist. V. non mediocriter.
(f) That is, with profane wisdom which fills but does not satisfy,
(g) XIIII. quaest V. dixit.
...offer up to God the first fruits of honey, that is, the sweetness of human eloquence. The Magi, too, offered three gifts, by which some would have us understand the three parts (h) of philosophy.
Finally in his exposition of the Psalms, Cassiodorus bears witness that all the splendor of rhetorical eloquence, all the melody of poetic speech, whatever variety there may be of pleasing pronunciation, have their origin in divine Scriptures.
Hence also Ambrose says concerning the Epistle to the Colossians: The sum total of celestial knowledge or of earthly creation is in Him who is their Fountain-head and Author, so that he who knows Him should not seek anything beyond, because He is goodness and wisdom in their completeness; whatever is sought elsewhere, in Him is found in its completeness. In Daniel and Solomon he shows that He is for infidels the source of all their eloquence and wisdom. Infidels do not so think, because they do not, in the Gospels and the prophets, read about astrology and other such like things, which are of slight (i) worth because they avail not for salvation, but lead to error; and whoever devotes himself to these has no care for his soul; while he who knows Christ finds a treasure house of wisdom and knowledge, because he knows that which is of avail.
Hence Bede says in the Book of Kings:
=The clergy should not be prevented from reading profane literature.=
He harms the mental acumen of readers, and causes it to wane, who thinks that they should in every way be prevented from reading profane books; for whatever useful things (k) are found in them it is lawful to adopt as one's own. Otherwise Moses and Daniel would not have been allowed to become learned in the wisdom and literature of the Egyptians and ...
(h) I.e. Ethics, natural philosophy, rational philosophy.
(i) Compared with other knowledge. John.
(k) He argues that the useful is not vitiated by the useless as XVII. q. IV. questi s. dist. IX. si ad scripturas. Contra Joan.
...Chaldeans, whose superstitions and wantonness nevertheless they shuddered at. And the teacher (l) of the gentiles himself would not have introduced (m) some verses of the poets into his own writings or sayings.
Then why are those [writings] forbidden to be read which, it ...
(l) For we read that when Paul had come to Athens he saw an altar of the Unknown God on which it was written: "This is an altar of the Unknown God in whom we live and move and have our being." And with this inscription the Apostle began his exhortation and made known to those Athenians the meaning of this inscription,--continuing about our God and saying: "Whom you pronounce Unknown, Him declare I unto you and worship." Then Dionysius, the Areopagite, seeing a blind man passing by said to him (i.e. Paul), "If you will give sight to that blind man I will believe you." Immediately, when the name of Christ had been invoked, he was restored to sight and Dionysius believed.
(m) E.g. In the Epistle of Paul to Titus, the quotation from Epimenides the poet: "The Cretians are always liars, evil beasts, slow bellies." I. quaest, i. dominus declaravit.
Also he introduced in the first Epistle to the Corinthians this from Menander: "Evil communications often corrupt good manners." XXVIII. quaestio I. saepe.
He used also this verse: "I shall hate if I can: if not, I shall love against my will." But Jerome in his fifth division on Consecration often used verses from Virgil and Augustine, this of Lucan's: "Mens hausti nulla" &c. XXVI. quaestio V. nee mirum. And, as a lawyer, he uses the authority of Vergil, ff. de rerum divisione, intantrum § cenotaphium; and also, of Homer, insti. de Dontrahen. emp. § pretium.
...is shown so reasonably, should be read? Some (n) read profane literature for their pleasure, being delighted with the productions of the poets and the charm of their words; while others learn them to add to their knowledge, in order that through reading the errors, of the heathen they may denounce them, and that they may turn to the service of sacred and devout learning the useful things they find therein. Such are praiseworthy in adding to their learning profane literature. Whence blessed Gregory did not blame a certain bishop for learning it but because, contrary to his episcopal obligation, he read grammar to the people in place of the Gospel lesson.
Hence also Ambrose writes concerning Luke:
=Profane writings should be read that they may not be unknown.=
Some we read (o) that we may not neglect (a) them; we read that we may not be ignorant of them; we read not that we may embrace them but that we may reject them.(b)
So Jerome on the Epistle to Titus:
=Grammar should be read in order that through it the Sacred Scriptures may be understood.=
If anyone has learned grammar or dialectics in order to have the ability to speak correctly and to discriminate between the true and the false, we do not blame them. Geometry (c) and Arithmetic and Music contain truth in their own range of knowledge, but that knowledge is not the knowledge of piety. The knowledge of piety is,--to know the law, to understand the prophets, to believe the Gospel, (and) not to be ignorant of the Apostles. Moreover the teaching of the grammarians can contribute to life, provided it has been applied to its higher uses.
