John Calvin on Paul’s reference to a Cretan author in Titus 1:12:

12 One of themselves, a prophet of their own
I have no doubt that he who is here spoken of is Epimenides, who was a native of Crete; for, when the Apostle says that this author was “one of themselves,” and was “a prophet of their own,” he undoubtedly means that he belonged to the nation of the Cretans. Why he calls him a Prophet–is doubtful. Some think that the reason is, that the book from which Paul borrowed this passage bears the title Περὶ Χρησμῶν “concerning oracles.” Others are of opinion that Paul speaks ironically, by saying that they have such a Prophet — a Prophet worthy of a nation which refuses to listen to the servants of God. But as poets are sometimes called by the Greeks ( προφὢται) “prophets,” and as the Latin authors call them Vates , I consider it to denote simply a teacher. The reason why they were so called appears to have been, that they were always reckoned to be ( γένος θεῖον καὶ ἐνθουσιαστικόν)“ a divine race and moved by divine inspiration.” Thus also Adimantus, in the Second Book of Plato’s treatise Περὶ Πολιτείας after having called the poets υἵους Θεῶν “sons of the gods,” adds, that they also became their prophets. For this reason I think that Paul accommodates his style to the ordinary practice. Nor is it of any importance to inquire on what occasion Epimenides calls his countrymen liars, namely, because they boast of having the sepulcher of Jupiter; but seeing that the poet takes it from an ancient and well-known report, the Apostle quotes it as a proverbial saying. (228)

From this passage we may infer that those persons are superstitious, who do not venture to borrow anything from heathen authors. All truth is from God; and consequently, if wicked men have said anything that is true and just, we ought not to reject it; for it has come from God. Besides, all things are of God; and, therefore, why should it not be lawful to dedicate to his glory everything that can properly be employed for such a purpose? But on this subject the reader may consult Basil’s discourse (229) πρὸς τοὺς νέους, ὅπως ἂν ἐξ ἑλλ κ.τ.λ

Read the whole thing HERE. I came across this quote in an article by the Calvinist International a while back.

Calvin’s answer (to ‘Should we read and quote non-Christians’) is obviously ‘Yes.’

This is interesting to me for a number of reasons:

1) I like reading non-Christians and quote them regularly. It’s nice when Calvin has your back. (I decided to post this today because I am going to meet one of my own favorite ‘heathen’ authors today at a book reading).

2) It acknowledges common grace in non-Christian authors, which implicitly endorses the reading of non-Christian authors as a source of learning (rather than simply reading with a view toward critique).

3) Calvin explicitly says superstition is the only thing that keeps us from reading such.

4) Paul calls the Cretan a “prophet.” Calvin has no great explanation for this. But if you take G.K. Chesterton’s idea that a prophet is essentially someone who sees the world (under the sun) as it actually is, then there should be no quibbles about some non-Christians having a quasi-prophetic perception of the world. Chesterton put it this way:

…If we see what is the real trend of humanity, we shall feel it most probable that he was stoned for saying that the grass was green and that the birds sang in spring; for the mission of all the prophets from the beginning has not been so much the pointing out of heavens or hells as primarily the pointing out of the earth.

Religion has had to provide that longest and strangest telescope – the telescope through which we could see the star upon which we dwelt…

So then, a worldly prophet is someone who sees the world, particularly the age, with insight, and therefore can accurately describe the state of the fallen world. We are called to learn from such.

This doesn’t bode well for those who would tell us we should only read books from ‘trusted sources’ that will surely never lead us astray. Holding such a position, Calvin says above, is from nothing other than superstition.
