Resch
151 Let no man, set in Christ's body, imagine these words to be alien from himself, since in truth it is the whole body of Christ placed in this humble state that speaks: “O consider my humiliation, and deliver me: for I forget not Your law”. In this place we cannot understand any law of God so suitably, as that whereby it is immutably determined that “every one that exalts himself, shall be abased; and every one that humbles himself; shall be exalted.”
152. “Avenge Thou,” he says, “my cause, and deliver me”. The former sentence is here almost repeated. And what is there said, “For I do not forget Your law,” agrees with what we read here, “Quicken me, according to Your word.” For these words are the law of God, which he has not forgot, so that he has abased himself, and will therefore be exalted. But the words, “Quicken me,” pertain to this very exaltation; for the exaltation of the saints is everlasting life.
153. “Health,” he says, “is far from the ungodly: for they regard not Your righteousnesses”. This separates you, that what they have not done, you have done, that is, you have regarded the righteousnesses of God. But “what have you that you have not received?” Are you not he who a little before said, “I will keep Your righteousnesses”? Thou therefore hast received from Him, unto whom you called, the power to keep them. He therefore does Himself separate you from those from whom health is far, because they have not regarded the righteousnesses of God.
154. This he saw himself also. For I should not see it, save I saw it in Him, save I were in Him. For these are the words of the Body of Christ, whose members we are. He saw this, I say, and at once added, “Great are Your mercies, O Lord”. Even our seeking out Your righteousnesses, then, comes of Your mercies. “Quicken me according to Your judgment.” For I know that Your judgments will not be upon me without Your mercy.
155. “Many there are that trouble me, and persecute me; yet do I not swerve from Your testimonies”. This has been realized: we know it, we recollect it, we acknowledge it. The whole earth has been crimsoned by the blood of Martyrs; heaven is flowery with the crowns of Martyrs, the Churches are adorned with the memorials of Martyrs, seasons distinguished by the birthdays of Martyrs, cures more frequent by the merits of Martyrs. Whence this, save because that has been fulfilled which was prophesied of that Man who has been spread abroad around the whole world. We recognize this, and render thanks to the Lord our God. For thou, man, you have yourself said in another Psalm, “If the Lord Himself had not been on our side, they would have swallowed us up quick.” Behold the reason why you have not swerved from His testimonies, and hast won the palm of your heavenly calling amid the hands of the many who persecuted and troubled you.
156. “I have seen,” he says, “the foolish, and I pined”: or, as other copies read, “I have seen them that keep not covenant:” this is the reading of most. But who are they who have not kept covenant, save they who have swerved from the testimonies of God, not bearing the tribulation of their many persecutors? Now this is the covenant, that he who shall have conquered shall be crowned. They who, not bearing persecution, have by denial swerved from the testimonies of God, have not kept the covenant. These then the Psalmist saw, and pined, for he loved them. For that jealousy is good, springing from love, not from envy. He adds in what respect they had failed to keep the covenant, “Because they kept not Your word.” For this they denied in their tribulations.
157. And he commends himself as differing from them, and says, “Behold, how I have loved Your commandments”. He says not, I have not denied Your words or testimonies, as the Martyrs were urged to do, and, when they refused, suffered intolerable torments: but he said this wherein is the fruit of all sufferings; for, “if I give up my body to be burned, and have not charity, it profits me nothing.” The Psalmist, praising this virtue, says, “Behold, how I have loved Your commandments.” Then he asks his reward, “O Lord, quicken me, according to Your mercy.” These put me to death, do Thou quicken me. But if a reward be asked of mercy, which justice is bound to give; how much greater is that mercy, which enabled him to gain the victory, on account of which the reward was sought for?
158. “The beginning,” he says, “of Your words is truth; all the judgments of Your righteousness endure for evermore”. From truth, he says, Your words do proceed, and they are therefore truthful, and deceive no man, for in them life is announced to the righteous, punishment to the ungodly. These are the everlasting judgments of God's righteousness.
