Notes, Explanatory and Practical, on the Old and New Testaments (1832-1869)
Because that - The apostle here is showing that it was right to condemn people for their sins. To do this it was needful to show them that they had the knowledge of God, and the means of knowing what was right; and that the true source of their sins and idolatries was a corrupt and evil heart. When they knew God - Greek, “knowing God.” That is, they had an acquaintance with the existence and many of the perfections of one God.

although they knew God
on Romans 1:21-23
They knew God and withheld worship and thanks, the root failure before a single idol is carved. Claiming wisdom, they became fools and traded the glory of the immortal God for images of man, birds, animals and reptiles. The list descends from man to reptiles, reversing Genesis 1.

They were so far from being ignorant that they confessed that there was a single principle from which all things heavenly, earthly and infernal derived their origin, and that there was only one being who decreed what properties and duties would belong to everything by …
If they had given thanks to God who gave this wisdom, they would not have claimed any credit for their own ideas. Therefore they were given over by the Lord to the desires of their own hearts, and did improper things.
Surely that darkening of the heart was already a penalty and punishment, and by that penalty, that is by the blinding of the heart because of the abandonment by the light of wisdom, they fell into more and more serious sins.
A spiritual disciple of this sort truly receiving the Spirit of God, who was from the beginning, in all the dispensations of God, present with mankind, and announced things future, revealed things present, and narrated things past-[such a man] does indeed "judge all men, but is himself judged by no man." For he judges the Gentiles, "who serve the creature more than the Creator," and with a reprobate mind spend all their labour on vanity.

For his invisible things, from the creation of the world, are clearly seen, being understood by the things that are made, and also his eternal power and divinity; so that they are inexcusable, because when they had known God, they did not magnify him as God, nor give thanks; but they became vain in their thoughts, and their foolish heart was darkened. For saying that they were wise, they became fools, and they changed the glory of the incorruptible God into the likeness of the image of corruptible man, and of birds, and of four-footed beasts, and of serpents. Almost every one of these points has already been discussed above. For we said that these things, although they pertain to all human beings in whom there is natural reason, nevertheless look chiefly to the wise men of this world and to those who are named philosophers, whose particular discipline it is to examine the creatures of the world and all the things that have been made in it, and through the things that are seen to gather by reasoning the things that are not seen. Yet it must be known that the invisible things which he here names, he speaks of concerning created things; about which the same Apostle also writes in another place: that all things were made through him, that is, through Jesus Christ, whether the things that are in heaven or the things that are on earth, visible and invisible. And therefore, besides those things which he called invisible, he adds: And his eternal power and divinity. Therefore the power of God, which is eternal, and the divinity, which is no less eternal, is recognized from inferences drawn from the creature. Power is that by which he governs all things; divinity that by which he fills the universe. […]

Now certainly the wretched ones were overwhelmed in the chaos of error, "because that, when they knew God, they glorified Him not as God, neither were thankful; but became vain in their imaginations, and their foolish heart was darkened; " and their wise men said that nothing earth-born was more honourable or more ancient than the Olympians. Whence they are not mere children who know Christ, like the Greeks, who, burying the truth in fairies and fictions, rather than in artistic words, ascribing human calamities to the heavens, are not ashamed to describe the circumference of the world by geometrical theorems and figures, and explain that the heaven is adorned with the images of birds and of animals that live in water and on dry land, and that the qualities of the stars were made from the calamities of the men of old, so that the movements of the planets, in their opinion, depended upon the same kind of bodies.

That idols are not gods, and that the elements are not to be worshipped in the place of gods. In the cxiiith Psalm it is shown that "the idols of the heathen are silver and gold, the work of men's hands. They have a mouth, and speak not; eyes have they, and see not. They have ears, and hear not; neither is there any breath in their mouth. Let those that make them be made like unto them." Also in the Wisdom of Solomon: "They counted all the idols of the nations to be gods, which neither have the use of eyes to see, nor noses to draw breath, nor ears to hear, nor fingers on their hands to handle; and as for their feet, they are slow to go. For man made them, and he that borrowed his own spirit fashioned them; but no man can make a god like unto himself. For, since he is mortal, he worketh a dead thing with wicked hands; for he himself is better than the things which he worshippeth, since he indeed lived once, but they never." In Exodus also: "Thou shalt not make to thee an idol, nor the likeness of anything." Moreover, in Solomon, concerning the elements: "Neither by considering the works did they acknowledge who was the workmaster; but deemed either fire, or wind, or the swift air, or the circle of the stars, or the violent water, or the sun, or the moon, to be gods. On account of whose beauty, if they thought this, let them know how much more beautiful is the Lord than they. Or if they admired their powers and operations, let them understand by them, that He that made these mighty things is mightier than they."
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 hath committed two evils: they have forsaken me the fountain of living water, and have dug for themselves broken cisterns." (Jer. ii. 13.) 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 hath no shape, underwent a most rueful shipwreck. But beside what has been said, he names also another cause of their error...

When I reflect, O Emperor Constantine, and often revolve in my mind the original condition of men, it is accustomed to appear alike wonderful and unworthy that, by the folly of one age embracing various superstitions, and believing in the existence of many gods, they suddenly arrived at such ignorance of themselves, that the truth being taken away from their eyes, the religion of the true God was not observed, nor the condition of human nature, since men did not seek the chief good in heaven, but on earth. And on this account assuredly the happiness of the ancient ages was changed. For, having left God, the parent and founder of all things, men began to worship the senseless works of their own hands. And what were the effects of this corruption, or what evils it introduced, the subject itself sufficiently declares. For, turning away from the chief good, which is blessed and everlasting on this account, because it cannot be seen, or touched, or comprehended, and from the virtues which are in agreement with that good, and which are equally immortal, gliding down to these corrupt and frail gods, and devoting themselves to those things by which the body only is adorned, and nourished, and delighted, they sought eternal death for themselves, together with their gods and goods relating to the body, because all bodies are subject to death.

Because, knowing God - For the wiser heathens did know that there was one supreme God; yet from low and base considerations they conformed to the idolatry of the vulgar. They did not glorify him as God, neither were thankful - They neither thanked him for his benefits, nor glorified him for his divine perfection. But became vain - Like the idols they worshipped.
We shall the less wonder at the inefficacy of these natural discoveries to prevent the idolatry of the Gentiles if we remember how prone even the Jews, who had scripture light to guide them, were to idolatry; so miserably are the degenerate sons of men plunged in the mire of sense.
To glorify him as God is to worship him with spiritual worship; but they made images of him. Not to glorify God as God is in effect not to glorify him at all; to respect him as a creature is not to glorify him, but to dishonour him.
Because that when they knew God,.... Though they had such a knowledge of the being and perfections of God, yet they glorified him not as God.

Knowledge is not a possession to be proud of, since it brings with it so great a responsibility that a nurse might as well be proud of watching over a life in peril.

‘So that they are without excuse: because that, when they knew God, they glorified him not as God, neither were thankful.’Romans 1:20, 21 THOSE who boast of their knowledge betray their ignorance. Knowledge is not a possession to be proud of, since it brings with it so great a responsibility that a nurse might as well be proud of watching over a life in peril. Knowledge may become good or ill according to the use which is made of it. If men know God, for instance, and then glorify him as God, and are thankful, their knowledge has become the means of great blessing to them; but if they know God, and fail to glorify him, their knowledge turns to their condemnation. There is a knowledge which does not puff up the mind, but builds up the soul, being joined with holy love. Did not our Lord say, ‘And this is life eternal, that they might know thee the only true God, and Jesus Christ, whom thou hast sent’? But for men to know God, and not to glorify him as God, and to be unthankful, is according to our text, no benefit to them: on the contrary, it becomes a savour of death unto them, because it leaves them without excuse. Our Saviour could plead for some, ‘Father, forgive them, for they know not what they do.’ But what plea is to be used for those who know what they do, and yet do evil; who know what they ought to do, and do it not? These have the light, and close their eyes; or, to use another figure, they have the light, and use it to sin by. They take the golden candlestick of the sanctuary into their hands, and by its help they perform their evil deeds the more dexterously, and run in the way of wickedness the more swiftly. Accursed is that man who heaps to himself knowledge till he becomes wise as Solomon, and then prostitutes it to base ends by using it to aggrandize his wealth, to pamper his appetites, to bolster his unbelief, or to conceal his vices.

Read it at home and be startled at the awful vices of the Gentile world. Unmentionable crimes were the common pleasures of those wicked ages! But the chapter is also a striking picture of heathenism at the present time. After a missionary had gone into a certain part of India and had given away New Testaments, a Hindu waited upon him and asked him this question—"Did you not write that first chapter in the Epistle to the Romans after you came here?" "No," replied the missionary, "I did not write it at all. It has been there nearly two thousand years." The Hindu said, "Well, if it has not been written since you came here, all I can say is, that it might have been so written, for it is a fearfully true description of the sin of India." It is also much more true, even of London, than some of us would like to admit. Even here are committed those vices, the very mention of which would make the cheek of modesty to crimson. However, I am not going to talk about India— they are a long way off. I am not going to speak about the ancient Romans—they lived a couple of thousand years ago. I am going to speak about ourselves and about some persons here whom my text admirably fits. I fear that I am speaking to some who are "without excuse: because that, when they knew God, they glorified Him not as God, neither were thankful." I. The first charge against those who are mentioned in my text is LACK OF REVERENCE. "They knew God," but "they glorified Him not as God." They knew that there was a God—they never denied His existence—but they had no reverence for His name. They did not render Him the homage to which He is entitled—they did not glorify Him as God.
Because that when they knew God - When they thus acquired a general knowledge of the unity and perfections of the Divine nature, they glorified him not as God - they did not proclaim him to the people, but shut up his glory (as Bishop Warburton expresses it) in their mysteries, and gave the people, in exchange for an incorruptible God, an image made like to corruptible man. Wherefore God, in punishment for their sins, thus turning his truth into a lie, suffered even their mysteries, which they had erected for a school of virtue, to degenerate into an odious sink of vice and immorality; giving them up unto all uncleanness and vile affections. They glorified him not - They did not give him that worship which his perfections required. Neither were thankful - They manifested no gratitude for the blessings they received from his providence, but became vain in their imaginations, διαλογισμοις, in their reasonings. This certainly refers to the foolish manner in which even the wisest of their philosophers discoursed about the Divine nature, not excepting Socrates, Plato, or Seneca. Who can read their works without being struck with the vanity of their reasonings, as well as with the stupidity of their nonsense, when speaking about God? I might crowd my page with proofs of this; but it is not necessary to those who are acquainted with their writings, and to others it would not be useful. In short, their foolish, darkened minds sought God no where but in the place in which he is never to be found; viz. the vile, corrupted, and corrupting passions of their own hearts. As they did not discover him there, they scarcely sought him any where else.
