A Self-Interrogation Concerning the Exercise Proper Before Communion

When I consider Your dignity, O Lord, and my own vileness, I am frightened exceedingly, and am confounded within myself.  For if I do not appeal to You, I fly from life; and if I intrude myself unworthily, I incur Your displeasure.  What, then, shall I do, O my God, my Helper and Counselor in necessities?  Teach me the right way; set before me some short exercise suitable for the Holy Communion.  For it is well to know after what manner, indeed, I ought devoutly and reverently to prepare my heart for You, for the profitable receiving of Your Sacrament, as well as for celebrating so great and divine a Sacrifice.
