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.
