From the Breviary according to the use of the Roman Curia, 1529, the continuation of the sermon for the fifth day in the Octave of All Saints.
Since we wish to venerate all the Saints, first of all let us venerate and praise with particular zeal the Lord God, whom we are ordered by the prophet to praise in His Saints. (Psalm 150, 1) “Let my soul be filled as with marrow and fatness”, he says, (Psalm 62, 8), that is, just as the soul is made perfect by interior faith and the perfection of exterior virtues, so the voice of the faithful must praise him with the sound of exultation. The prophet’s meaning is this: Just as from a vessel comes forth the odor of that which fills it, so divine praise comes forth from the soul that is full of the love of God, expressed with the sound of exultation and devotion. By this praise God is appeased and honored, and grace conferred upon man for his good. “The sacrifice of praise shall glorify me: and there is the way by which I will show him the salvation of God.” (Psalm 49, 23)
