Ps 49:23

“Let us … earnestly strive to be found in the number of those that wait for him, in order that we may share in his promised gifts. But how, beloved, shall this be done? If our understanding is fixed by faith toward God; if we earnestly seek the things that are pleasing and acceptable to him; if we do the things that are in harmony with his blameless will; and if we follow the way of truth, casting away from us all unrighteousness and iniquity, along with all covetousness, strife, evil practices, deceit, whispering and evil speaking, all hatred of God, pride and haughtiness, vainglory and ambition. For they that do such things are hateful to God; and not only they that do them, but also those that take pleasure in them that do them.”

“Who among us is of such measure and kind to offer to God "salutary sacrifices" and a "sacrifice of praise"? I believe that one to be a person who praises God in all his actions and fulfills through him what our Lord and Savior says: "That people may see your good works and praise your Father who is in heaven." Therefore, this one offered "a sacrifice of praise" for whose deeds, doctrine, word, habits and discipline, God is praised and blessed. Just as, on the contrary, there are those of whom it is said, "Through you my name is blasphemed among the Gentiles."”

“"Sacrifice of praise shall glorify Me" [Psalm 50:23]. How shall "sacrifice of praise glorify Me"? Assuredly sacrifice of praise does no wise profit evil men, because they take Your Covenant in their mouth, and do damnable things that displease Your eyes. Straightway, he says, even to them this I say, "Sacrifice of praise shall glorify Me." For if you live ill and speakest good words, not yet do you praise: but again, if, when you begin to live well, to your merits thou dost ascribe your living well, not yet do you praise....Therefore the Publican went down justified, rather than that Pharisee. Therefore hear ye that live well, hear ye that live ill: "Sacrifice of praise shall glorify Me." No one offers Me this sacrifice, and is evil. I say not, Let there not offer Me this any one that is evil; but no one does offer Me this, that is evil. For he that praises, is good: because if he praises, he does also live well, because if he praises, not only with tongue he praises, but life also with tongue does agree.”

“For this ointment is made from the gifts of God bestowed on the human race. Happy the man who makes it his business to gather these carefully for himself and keep them in mind with due thanksgiving. When they shall have been pounded and refined in the heart's receptacle with the pestle of frequent meditation, all of them fused together in the fire of holy desire, and finally enriched with the oil of gladness, you will have an ointment more excellent than the former, and far more precious. Enough proof can be found in the words of him who said: "Whoever makes thanksgiving his sacrifice honors me." No one doubts that the recalling of favors is an incentive to praise. Furthermore, since the only thing that Scripture says of the former ointment is that God does not despise it, it follows that the second one, which especially glorifies him, is the more highly commended. Therefore the former is applied to the feet, the latter to the head. St Paul says: "God is the head of Christ," so in speaking of Christ we may understand the head as referring to his divinity, and it is beyond doubt that he who offers thanks anoints the head, because he makes contact with God, not man. I do not mean that he who is God is not also man, for the one Christ is both God and man; I mean that all things which are good, even those of which man is the agent, really come from God rather than man. "It is the spirit," we are told, "that gives life, the flesh has nothing to offer." Hence there is a curse on the man who puts his trust in man, for although our whole hope rightly depends on God made man, it is not because he is man but because he is God. Therefore the first ointment is applied to the feet, the second to the head, because the humiliation of a broken heart fittingly corresponds to the lowliness of the flesh, and honor is owed to majesty. See then what an ointment I have been describing for you, with which he before whom even the Principalities stand in awe, does not disdain to be anointed on the head. Rather does he regard it as a matter of signal honor, for he says: "Whoever makes thanksgiving his sacrifice honors me."”

“"The sacrifice of praise shall honor me." Here he concludes what is acceptable to God in sacrifices. And he shows a twofold fruit in them. One fruit is on the part of God, that his excellence may be manifested; and this is done through the sacrifice of vocal praise. 1 Cor. 10: "Do all things for the glory of God." The other fruit is on our part, namely true salvation. Hence he says, "And there is the way by which I will show him the salvation of God," that is, unto seeing God. Is. 52: "They shall lift up their voice; together they shall praise." Jerome has, "And he who walks in an orderly manner, I will show him the salvation of God"; as if to say: two things are necessary for salvation, namely the sacrifice of praise and that you walk in an orderly manner.”
