This is the one greatest charge; and the second after it is their also worshipping idols, as Jeremy too in accusing them said, “This people has committed two evils: they have forsaken me the fountain of living water, and have dug for themselves broken cisterns.” And then as a sign of their having known God, and not used their knowledge upon a fit object, he adduces this very thing, that they knew gods. Wherefore he adds, “because that, when they knew God, they glorified Him not as God.” And he names the cause through which they fell into such senselessness. What then is it? They trusted everything to their reasonings. Still he does not word it so, but in a much sharper language, “but became vain in their reasonings, and their foolish heart was darkened.” For as in a night without a moon, if any one attempt to go by a strange road, or to sail over a strange sea, so far will he be from soon reaching his destination, that he will speedily be lost. Thus they, attempting to go the way leading to Heaven, and having destroyed the light from their own selves, and, in lieu of it, trusted themselves to the darkness of their own reasoning, and seeking in bodies for Him who is incorporeal, and in shapes for Him who has no shape, underwent a most rueful shipwreck. But beside what has been said, he names also another cause of their error, when he says,
Ver. 22. “Professing themselves to be wise, they became fools.”
For having some great conceit of themselves, and not enduring to go the way which God had commanded them, they were plunged into the reasonings of senselessness (1 manuscript διανοίας). And then to show and give in outline, what a rueful surge it was, and how destitute of excuse, he goes on to say,
Ver. 23. “And changed the glory of the uncorruptible God into an image made like to corruptible man, and to birds, and four-footed beasts, and creeping things.”
The first charge is, that they did not find God; the second was, that it was while they had great and clear (Sav. marg. “wise”) means to do it; the third, that withal they said they were wise; the fourth, that they not only did not find that Reverend Being, but even lowered Him to devils and to stones and stocks. Now he takes down their haughtiness also in the Epistle to the Corinthians, but not in the same way there as here. For there it is from the Cross he gives them the blow, saying, “The foolishness of God is wiser than men.” But here, without any comparison, he holds their wisdom by itself up to ridicule, showing it to be folly and a mere display of vain boasting. Then, that you may learn that when they had the knowledge of God they gave it up thus treacherously, “they changed,” he says. Now he that changes, has something to change. For they wished to find out more, and not bear with the limits given them, and so they were banished from these also. For they were lusters after new devices, for such is all that is Grecian. And this is why they stood against one another and Aristotle rose up against Plato, and the Stoics blustered (ἐ φρυάξαντο 6 manuscripts “fenced themselves,” ἐ φράξαντο: which Field inclines to prefer) against him, and one has become hostile to one, another to another. So that one should not so much marvel at them for their wisdom, as turn away from them indignant and hate them, because through this very thing they have become fools. For had they not trusted what they have to reasonings, and syllogisms, and sophistries, they would not have suffered what they did suffer. Then, to strengthen the accusation against them he holds the whole of their idolatry up to ridicule. For in the first place the changing even were a very fit subject of scorn. But to change to such things too, is beyond all excuse. For what then did they change it, and what was it which they invested with His Glory? Some conceptions they ought to have had about Him, as, for instance, that He is God, that He is Lord of all, that He made them, which were not, that He exercises a Providence, that He cares for them. For these things are the “Glory of God.” To whom then did they ascribe it? Not even to men, but “to an image made like to corruptible man.” Neither did they stop here, but even dropped down to the brutes, or rather to the images of these. But consider, I pray, the wisdom of Paul, how he has taken the two extremes, God the Highest, and creeping things the lowest: or rather, not the creeping things, but the images of these; that he might clearly show their evident madness. For what knowledge they ought to have had concerning Him Who is incomparably more excellent than all, with that they invested what was incomparably more worthless than all. But what has this to do with the philosophers? A man may say. To these belongs most of all what I have said to do with them. For they have the Egyptians who were the inventors of these things to their masters. And Plato, who is thought more reverend than the rest of them, glories in these masters. (Plat. Tim. 21. B. etc.) And his master is in a stupid awe of these idols, for he it is that bids them sacrifice the cock to Æsculapius (his last words, Phædo), where (i.e. in his temple. So Field from manuscripts.) are the images of these beasts, and creeping things. And one may see Apollo and Bacchus worshipped along with these creeping things. And some of the philosophers even lifted up to Heaven bulls, and scorpions, and dragons, and all the rest of that vanity. For in all parts did the devil zealously strive to bring men down before the images of creeping things, and to range beneath the most senseless of all things, him whom God has willed to lift up above the heavens. And it is not from this only, but also from other grounds, that you will see their chief man to come under the remarks now made. For having made a collection of the poets, and having said that we should believe them upon matters relating to God, as having accurate knowledge, he has nothing else to bring forward but the “linked sweetness” of these absurdities, and then says, that this utterly ludicrous trifling is to be held for true.
Ver. 24. “Wherefore also God gave them up to uncleanness, through the lusts of their own hearts, to dishonor their own bodies between themselves.”
Hence he shows, that even of the perversion of the laws it was ungodliness which was the cause, but He “gave them up,” here is, let them alone. For as he that has the command in an army, if upon the battle lying heavy upon him he retreat and go away, gives up his soldiers to the enemies not by thrusting them himself, but by stripping them of his own assistance; thus too did God leave those that were not minded to receive what comes from Him, but were the first to bound off from Him, though Himself having wholly fulfilled His own part. But consider; He set before them, for a form of doctrine, the world; He gave them reason, and an understanding capable of perceiving what was needful. None of these things did the men of that day use unto salvation, but they perverted to the opposite what they had received. What was to be done then? To drag them by compulsion and force? But this were not to make them virtuous. It remained then, after that, for Him to leave them alone, and this He did too, that in this way, if by no other, having by trial come to know the things they lusted after, they might flee from what was so shameful (3 manuscripts add εἰκότως, and with reason). For if any that was a king's son, dishonoring his father, should choose to be with robbers and murderers, and them that break up tombs, and prefer their doings to his father's house; the father leaves him, say, so that by actual trial, he may learn the extravagance of his own madness. But how comes he to mention no other sin, as murder, for instance, or covetousness, or other such besides, but only unchasteness? He seems to me to hint at his audience at the time, and those who were to receive the Epistle. “To uncleanness, to dishonor their own bodies between themselves.”
