How it differs from metaphor and the other tropes of figurative speech, caeteris tropis, we learned in school as children. It says one thing in words and another in the meaning joined to them. The books of orators and poets are full of allegories. Divine Scripture too is composed in great part by means of them. Bearing this in mind, the Apostle Paul, who had also touched somewhat on secular books, used the very name of the trope. He called it allegory, as this was said among his countrymen. Thus, by the true meaning of this place, he showed how Greek writers misuse this trope. That the Apostle Paul, though not perfectly, still knew secular writings is witnessed by his own words: "One of them, a prophet of their own, said: Cretans are always liars, evil beasts, lazy bellies" (Tit. 1:12). This is the so-called heroic verse of the writer Epimenides, whom Plato and the other ancient writers also mention. Likewise, when speaking before the Athenians in the Areopagus, he added: "As even some of your poets have said: For we too are His offspring" (Acts 17:28). This half-line is found in the verses of Aratus, who wrote about the heavens and the stars. There is also another passage: "Most wicked inventions have corrupted good morals" (1 Cor. 15:33). This is an iambic trimeter taken from a comedy of Menander. From these and other places it is evident that secular books were not unknown to Paul. What he here called allegory, elsewhere he called spiritual understanding. For example: "We know that the Law is spiritual" (Rom. 7:14), instead of saying that it is allegory or an allegorical trope. Elsewhere: "All ate the same spiritual food, and all drank the same spiritual drink. For they drank from the spiritual Rock that followed them, and the Rock was Christ" (1 Cor. 10:3-4). No one doubts that here the manna, the sudden formation of the spring, and the Rock that followed them must be understood allegorically. I know that the contrary word may be set against this: "Brethren, if a man is suddenly overtaken by some sin, you who are spiritual restore such a one in a spirit of meekness" (Gal. 6:1). And elsewhere: "The spiritual man judges all things, but he himself is judged by no one." This is because the word "spiritual" has another meaning than the one we gave above. But by the spiritual man who judges all things and is judged by no one, we understand such a man as knows all the sacred mysteries of the Scriptures, sacramenta Scripturarum. He understands them excellently, sees Christ in the divine books, and admits nothing in them from Jewish tradition.
