116. The Priestly Office From St. Gregory Nazianzen. IN service o'er the Mystic Feast I stand; I cleanse Thy victim-flock, and bring them near In holiest wise, and by a bloodless rite. O fire of Love! O gushing Fount of Light! (As best I know, who need Thy pitying Hand) Dread office this, bemired souls to clear Of their defilement, and again made bright. Oxford . 1834.
