Gimel
15 He had said, “Wherewithal shall a young man cleanse his way? Even by keeping Your words.” Behold he now more openly asks aid that he may do this: “Reward,” he says, “Your servant: let me live, and keep Your word”...It this reward that he asks, who says, “Reward Your servant.” For there are four modes of reward: either evil for evil, as God will reward everlasting fire to the unrighteous; or good for good, as He will reward an everlasting kingdom to the righteous; or good for evil, as Christ by grace justifies the ungodly; or evil for good, as Judas and the Jews through their wickedness persecuted Christ. Of these four modes of reward, the first two belong to justice, whereby evil is rewarded for evil, good for good; the third to mercy, whereby good is rewarded for evil; the fourth God knows not, for to none does He reward evil for good. But that which I have placed third in order, is in the first instance necessary: for unless God rewarded good for evil, there would be none to whom He could reward good for good....
16. Nowhere then let human pride raise itself up: God gives good rewards unto His own gifts....
17. “Open Thou my eyes, and I will consider wondrous things of Your law”. What he adds, “I am a lodger upon earth”: or, as some copies read, “I am a sojourner upon earth, O hide not Your commandments from me,” has the same meaning....
18. Here an important question arises respecting the soul. For the words, I am a sojourner, or lodger, or stranger upon earth, cannot seem to have been said in reference to the body, since the body derives its origin from the earth. But in this most profound question I dare not define anything. For if it might justly have been said in respect of the soul (which God forbid we should suppose derived from the earth), “I am a lodger,” or “stranger upon earth;” or in reference to the whole man, since he was at one time an inhabitant of Paradise, where he who spoke these words was not; or, what is more free from all controversy, if it be not every man who could say this, but one to whom an everlasting country has been promised in heaven: this I know, “that the life of man on earth is a temptation;” and that “there is a heavy yoke upon the sons of Adam.” But it pleases me more to discuss the question in accordance with this construction, that we say we are tenants or strangers upon earth, because we have found our country above, whence we have received a pledge, and where when we have arrived we shall never depart....
19. Those whose conversation is in heaven, as far as they abide here conversant, are in truth strangers. Let them pray therefore that the commandments of God may not be hidden from them, whereby they may be freed from this temporary sojourn, by loving God, with whom they will be for evermore; and by loving their neighbour, that he may be there where they also themselves will be.
20. But what is loved by loving, if love itself be not loved? Whence by consequence that stranger upon earth, after praying that the commandments of God might not be hidden from him, wherein love is enjoined either solely or principally; declares that he desires to have a love for love itself, saying, “My soul has coveted to have a desire always after Your judgments”. This coveting is worthy of praise, not of condemnation....
21. But he says not, “covets,” only; but, “My soul has coveted to desire Your judgments.” For there is no obstacle to possessing the judgments of God, save that they are not desired, while love has no warmth toward winning them, though their light is so clear and shining....
22. “You have rebuked the proud: and cursed are they that do err from Your commandments”. For the proud err from the commandments of God. For it is one thing not to fulfil the commandments of God through infirmity or ignorance; another to err from them through pride; as they have done, who have begotten us in our mortal state unto these evils....But consider now, after saying, “You have rebuked the proud,” he says not, Cursed are they that have erred from Your commandments; so that only that sin of the first men should come into the mind; but he says, “Cursed are they that do err.” For it was needful that all might be terrified by that example, that they might not err from the divine commandments, and by loving righteousness in all time, recover in the toil of this world, what we lost in the pleasure of Paradise.
23. “O turn from me shame and rebuke; for I have sought out Your testimonies”. Testimonies are called in Greek μαρτύρια, which word we now use for the Latin word: whence those who on account of their testimony to Christ have been brought low by various sufferings, and have contended unto death for the truth, are not called testes, but by the Greek term Martyrs. Since then ye hear in this term one more familiar and grateful, let us take these words as if it were said, “O turn from me shame and rebuke; because I have sought out Your martyrdoms.” When the body of Christ speaks thus, does it consider it any punishment to hear rebuke and shame from the ungodly and the proud, since it rather reaches the crown by this means? Why then does it pray that it should be removed from it as something heavy and insupportable, save because, as I said, it prays for its very enemies, to whom it sees it is destructive, to cast the holy name of Christ as a reproach to Christians....For my enemies, whom Thou enjoinest to be loved by me, who more and more die and are lost, when they despise Your martyrdoms and accuse them in me, will indeed be recalled to life and be found, if they reverence Your martyrdoms in me. Thus it has happened: this we see. Behold, martyrdom in the name of Christ, both with men and in this world, is not only not a disgrace, but a great ornament: behold, not only in the sight of the Lord, but in the sight of men, “precious is the death of His Saints;” behold, His martyrs are not only not despised, but honoured with great distinctions....
24. “Princes also did sit and speak against me: but Your servant is exercised in Your statutes”. Thou who desirest to know what sort of exercise this was, understand what he has added, “For Your testimonies are my meditation, and Your statutes are my counsellors”. Remember what I have above instructed you, that testimonies are acts of martyrdom. Remember that among the statutes of the Lord there is none more difficult and more worthy of admiration, than that every man should love his enemies. Thus then the body of Christ was exercised, so that it meditated on the acts of martyrdom that testified of Him, and loved those from whom, while they rebuked and despised the Church for these very martyrdoms, she suffered persecutions....
