Psalms 50:15

But what shall we say concerning David, to whom such testimony was borne, and of whom God said, “I have found a man after Mine own heart, David the son of Jesse; and in everlasting mercy have I anointed him?” Yet this very man saith to God, “Have mercy on me, O Lord, according to Thy great mercy; and according to the multitude of Thy compassions, blot out my transgression. Wash me still more from mine iniquity, and cleanse me from my sin. For I acknowledge my iniquity, and my sin is ever before me. Against Thee only have I sinned, and done that which was evil in Thy sight; that Thou mayest be justified in Thy sayings, and mayest overcome when Thou art judged. For, behold, I was conceived in transgressions, and in my sins did my mother conceive me. For, behold, Thou hast loved truth; the secret and hidden things of wisdom hast Thou shown me. …

12. But since you said that all religions by diverse roads and pathways aspire to that one dwelling-place, I fear lest, perchance, while supposing that the way in which you are now found tends thither, you should be somewhat reluctant to embrace the way which alone leads men to heaven. Observing, however, more carefully the word which you used, I think that it is not presumptuous for me to expound its meaning somewhat differently; for you did not say that all religions by diverse roads and pathways reach heaven, or reveal, or find, or enter, or secure that blessed land, but by saying in a phrase deliberately weighed and chosen that all religions aspire to it, you have indicated, not the fruition, but the desire of heaven as common to all religions. …

18. But see what he annexeth: “With Principal Spirit,” he saith, “confirm Thou me.” Wherein “confirm”? Because Thou hast pardoned me, because I am secure, that what Thou hast forgiven is not to be ascribed, on this being made secure and with this grace confirmed, therefore I am not ungrateful. But I shall do what? “I would teach unrighteous men Thy ways” ( ver. 13 ). Being myself of the unrighteous (that is, one that was myself an unrighteous man, now no longer unrighteous; the Holy Spirit not having been taken away from me, and I being confirmed with Principal Spirit). …

For there are two ways in life, as touching these matters. The one the more moderate and ordinary, I mean marriage; the other angelic and unsurpassed, namely virginity. Now if a man choose the way of the world, namely marriage, he is not indeed to blame; yet he will not receive such great gifts as the other. For he will receive, since he too brings forth fruit, namely thirtyfold. But if a man embrace the holy and unearthly way, even though, as compared with the former, it be rugged and hard to accomplish, yet it has the more wonderful gifts: for it grows the perfect fruit, namely an hundredfold. So then their unclean and evil objections had their proper solution long since given in the divine Scriptures. …

The whole repentance of a sinner is exhibited to us in the fifty-first psalm written by David after he had gone in unto Bathsheba the wife of Uriah the Hittite, and when, to the rebuke of the prophet Nathan he had replied, “I have sinned.” Immediately that he confessed his fault he was comforted by the words: “the Lord also hath put away thy sin.” He had added murder to adultery; yet bursting into tears he says: “Have mercy upon me, O God, according to thy loving kindness: according unto the multitude of thy tender mercies blot out my transgressions.” A sin so great needed to find great mercy. Accordingly he goes on to say: “Wash me thoroughly from mine iniquity, and cleanse me from my sin. For I acknowledge my transgressions: and my sin is ever before me. …

16. I will instruct thee of that which is written, that the Spirit is not at every time found with those that receive it. For thus it is written about Saul, that the Holy Spirit, which he received when he was anointed, departed from him , because he grieved it, and God sent to him instead of it a vexing spirit. And whenever he was afflicted by the evil spirit, David used to play upon the harp, and the Holy Spirit, which David received when he was anointed, would come, and the evil spirit that was vexing Saul, would flee from before it. So the Holy Spirit that David received was not found with him at every time. As long as he was playing the harp, then it used to come. For had it been with him always, it would not have allowed him to sin with the wife of Uriah. …
