In a Holy Fear
Holy Mass celebrated worthily, reverently, and carefully is itself the most convincing of sermons. The priest who stands before the altar in a holy fear, and who serves the Lord in reverence and with love, will touch more hearts than the most eloquent of preachers.
Not to Be Seen but to See
At the altar a priest preaches with his whole being. He enters into the sanctuary not to be seen, but to see, and in seeing the radiance of the glory of the Lord concealed in the Mysteries of His Body and Blood, he becomes to all a sign of His real presence and a witness of His glory, and this more perfectly than Moses when he descended from the holy mountain transfigured by the divine brightness.
