Psalms 30:20

And they deny that thus God’s threat of judgment is proved to be false even though He condemn no man, any more than we can say that His threat to overthrow Nineveh was false, though the destruction which was absolutely predicted was not accomplished. For He did not say, “Nineveh shall be overthrown if they do not repent and amend their ways,” but without any such condition He foretold that the city should be overthrown. And this prediction, they maintain, was true because God predicted the punishment which they deserved, although He was not to inflict it. For though He spared them on their repentance yet He was certainly aware that they would repent, and, notwithstanding, absolutely and definitely predicted that the city should be overthrown. …

But that these perversely compassionate persons may see what is the purport of these words, “How great is the abundance of Thy sweetness, Lord, which Thou hast hidden for them that fear Thee,” let them read what follows: “And Thou hast perfected it for them that hope in Thee.” For what means, “Thou hast hidden it for them that fear Thee,” “Thou hast perfected it for them that hope in Thee,” unless this, that to those who through fear of punishment seek to establish their own righteousness by the law, the righteousness of God is not sweet, because they are ignorant of it? They have not tasted it. For they hope in themselves, not in Him; and therefore God’s abundant sweetness is hidden from them. …

It is in vain, then, that some, indeed very many, make moan over the eternal punishment, and perpetual, unintermitted torments of the lost, and say they do not believe it shall be so; not, indeed, that they directly oppose themselves to Holy Scripture, but, at the suggestion of their own feelings, they soften down everything that seems hard, and give a milder turn to statements which they think are rather designed to terrify than to be received as literally true. For “Hath God” they say, forgotten to be gracious? hath He in anger shut up His tender mercies?” Now, they read this in one of the holy psalms. But without doubt we are to understand it as spoken of those who are elsewhere called “vessels of mercy,” because even they are freed from misery not on account of any merit of their own, but solely through the pity of God. …

3. It is amazingly bold in the impious and impure sect of the Manichæans to boast of being the chaste bride of Christ. All the effect of such a boast on the really chaste members of the holy Church is to remind them of the apostle’s warning against deceivers: "I have joined you to one husband, to present you as a chaste virgin to Christ. But I fear lest, as the serpent deceived Eve by his guile, so your minds also should be corrupted from the purity which is in Christ." What else do those preachers of another gospel than that which we have received try to do, but to corrupt us from the purity which we preserve for Christ, when they stigmatize the law of God as old, and praise their own falsehoods as new, as if all that is new must be good, and all that is old bad? The Apostle John, however, praises the old commandment, and the Apostle Paul bids us avoid novelties in doctrine. …

The righteousness of the law is proposed in these terms, that whosoever shall do it shall live in it; and the purpose is, that when each has discovered his own weakness, he may not by his own strength, nor by the letter of the law (which cannot be done), but by faith, conciliating the Justifier, attain, and do, and live in it. For the work in which he who does it shall live, is not done except by one who is justified. His justification, however, is obtained by faith; and concerning faith it is written, “Say not in thine heart, Who shall ascend into heaven? (that is, to bring down Christ therefrom;) or, Who shall descend into the deep? (that is, to bring up Christ again from the dead.) But what saith it? The word is nigh thee, even in thy mouth, and in thy heart: that is (says he), the word of faith which we preach: That if thou shalt confess with thy mouth the Lord Jesus, and shalt belie …

20. “How great” is “the multitude of Thy sweetness, O Lord” ( ver. 19 ). Here the Prophet exclaims, having sight of all this, and admiring how manifoldly plenteous is Thy sweetness, O Lord. “Which Thou hast hid for them that fear Thee.” Even those, whom Thou correctest, Thou lovest much: but lest they should go on negligently from relaxed security, Thou hidest from them the sweetness of Thy love, for whom it is profitable to fear Thee. “Thou hast perfected it for them that hope in Thee.” But Thou hast perfected this sweetness for them that hope in Thee. For Thou dost not withdraw from them what they look for perseveringly even unto the end. “In sight of the sons of men.” For it does not escape the notice of the sons of men, who now live no more after Adam, but after the Son of Man. …
