19. “I will confess to the Lord according to His justice” (ver. 17). This is not the sinner’s confession: for he says this, who said above most truly, “If there be iniquity in my hands:” but it is a confession of God’s justice, in which we speak thus, Verily, O Lord, Thou art just, in that Thou both so protectest the just, that Thou enlightenest them by Thyself; and so orderest sinners, that they be punished not by Thine, but by their own malice. This confession so praises the Lord, that the blasphemies of the ungodly can avail nothing, who, willing to excuse their evil deeds, are unwilling to attribute to their own fault that they sin, that is, are unwilling to attribute their fault to their fault. Accordingly they find either fortune or fate to accuse, or the devil, to whom He who made us hath willed that it should be in our power to refuse consent: or they bring in another nature, which is not of God: wretched waverers, and erring, rather than confessing to God, that He should pardon them. For it is not fit that any be pardoned, except he says, I have sinned. He, then, that sees the deserts of souls so ordered by God, that while each has his own given him, the fair beauty of the universe is in no part violated, in all things praises God: and this is not the confession of sinners, but of the righteous. For it is not the sinner’s confession when the Lord says, “I confess to Thee, O Lord of heaven and earth, because Thou hast hid these things from the wise, and revealed them to babes.” Likewise in Ecclesiasticus it is said, “Confess to the Lord in all His works: and in confession ye shall say this, All the works of the Lord are exceeding good.” Which can be seen in this Psalm, if any one with a pious mind, by the Lord’s help, distinguish between the rewards of the righteous and the penalties of the sinners, how that in these two the whole creation, which God made and rules, is adorned with a beauty wondrous and known to few. Thus then he says, “I will confess to the Lord according to His justice,” as one who saw that darkness was not made by God, but ordered nevertheless. For God said, “Let light be made, and light was made.” He did not say, Let darkness be made, and darkness was made: and yet He ordered it. And therefore it is said, “God divided between the light, and the darkness: and God called the light day, and the darkness He called night.” This is the distinction, He made the one and ordered it: but the other He made not, but yet He ordered this too. But now that sins are signified by darkness, so is it seen in the Prophet, who says, “And thy darkness shall be as the noon day:” and in the Apostle, who says, “He that hateth his brother is in darkness:” and above all that text, “Let us cast off the works of darkness, and let us put on the armour of light.” Not that there is any nature of darkness. For all nature, in so far as it is nature, is compelled to be. Now being belongs to light: not being to darkness. He then that leaves Him by whom he was made, and inclines to that whence he was made, that is, to nothing, is in this sin endarkened: and yet he does not utterly perish, but he is ordered among the lowest things. Therefore after the Psalmist said, “I will confess unto the Lord:” that we might not understand it of confession of sins, he adds lastly, “And I will sing to the name of the Lord most high.” Now singing has relation to joy, but repentance of sins to sadness.
