“Hence we should know that the Holy Spirit has condemned those detestable people who hold such views. For what other people does he specifically condemn except the Arians, who say that the Son of God does not experience periods of time and years? For there isn't anything with which that God is not familiar. If, however, Christ is God and Christ is the highest God, then he is God above all things. Notice how outraged the blessed David was with such people who limit the Son of God's knowledge. He says, "They do not share the troubles common to human beings, and they will not be plagued like other people. They are burdened with their pride; they are clothed in iniquity and impiety. Their iniquity is proportionate with their portliness. They extend into the condition of the heart." Without a doubt he condemns those who believe that divine things must be determined from the "condition of the heart." For God is not subject to [any temporal] condition or order because these are things that are peculiar to human beings and according to succeeding generations. But we know that they do not always occur according to some formal plan but more often happen according to some secret and hidden mystery."They have thought," he says, "and they have spoken wickedly and sinfully against God. They have set their mouth against heaven." And so we see that he condemns those who are responsible for impious blasphemy and who claim for themselves the right to arrange the secrets of heaven according to the manner of human nature.”

“Wherefore on this account what do these men, while they are not scourged, while they labour not with men? "Therefore," he saith "there hath holden them pride" (ver. 6). Observe these men, proud, undisciplined; observe the bull, devoted for a victim, suffered to stray at liberty; and to damage whatever he may, even up to the day of his slaughter. Now it is a good thing, brethren, that we should hear in the very words of a prophet of this bull as it were, whereof I have spoken. For thus of him the Scripture doth make mention in another place: he saith that they are, as it were, made ready as for a victim, and that they are spared for an evil liberty. "Therefore," he saith, "there hath holden them pride." What is, "there hath holden them pride"? "They have been clothed about with their iniquity and ungodliness." He hath not said, covered; but, "clothed about," on all sides covered up with their ungodliness. Deservedly miserable, they neither see nor are seen, because they are clothed about; and the inward parts of them are not seen. For whosoever could behold the inward parts of evil men, that are as it were happy for a time, whosoever could see their torturing consciences, whosoever could examine their souls racked with such mighty perturbations of desires and fears, would see them to be miserable even when they are called happy. But because "they are clothed about with their iniquity and ungodliness," they see not; but neither are they seen. The Spirit knew them, that saith these words concerning them: and we ought to examine such men with the same eye as that wherewith we know that we see, if there is taken from our eyes the covering of ungodliness. ...”

“Therefore, they wear pride as a necklace Because of this, pride adorns them as a necklace, insofar as it ascends upon his neck. the robbery that they commit envelopes their hips The robbery they commit makes them fat, enveloping their buttocks and hips with thickness of fat and flesh.”

“"Therefore..." They will wear arrogance around their necks, like a necklace, and their pride will cover them like a garment of violence. This is expressed by the phrase "Violence covers them as a garment." They will constantly be enveloped in this garment of violence, just as a person wears their clothing all day long.”

“Therefore pride compasseth them about as a chain, Which was the sin of the devils, and of our first parents, and of Sodom, and is the sin of antichrist; and which, of all sins, is most hateful to God; this arises from, at least is increased by, outward prosperity. Jeshurun waxed fat and kicked; pride and fulness of bread went together in Sodom; and, where it is predominant, it binds as a chain; such who are under the power of it are slaves unto it, they are chained and fettered by it, and it possesses them wholly; it shows itself in the several members of their bodies, in their eyes and feet, their walk and gait, and in their conduct and behaviour, and in the several actions of their lives, and is rightly called "the pride of life"; or rather they bind it about themselves as a chain, fancying it to be an ornament to them, what sets them off, and makes them look great in the eyes of others; whereas the reverse is what is of great price, and in high esteem with God and good men; namely, the ornament of a meek and quiet spirit: violence covereth them as a garment; wicked men that are prosperous and proud are generally oppressive to others; and are very often open in their acts of violence, which are as openly done and to be seen of all men, as the clothes upon their backs; and frequently the clothes they wear are got by rapine and oppression, so that they may properly be called garments of violence; see Isa 59:6.”
