From the novel, Loss and Gain
by Venerable John Henry Newman, C.O.

" A priest, or at least an assistant, had mounted for a moment above the altar, and removed a chalice or vessel which stood there; he could not see distinctly. A cloud of incense was rising on high; the people suddenly all bowed low; what could it mean? the truth flashed on him, fearfully yet sweetly; it was the Blessed Sacrament—it was the Lord Incarnate who was on the altar, who had come to visit and to bless His people. It was the Great Presence, which makes a Catholic Church different from every other place in the world; which makes it, as no other place can be, holy. The Breviary offices were by this time not unknown to Reding; and as he threw himself on the pavement, in sudden self-abasement and joy, some words of those great Antiphons came into his mouth, from which Willis had formerly quoted: 'O Adonai, et Dux domûs Israel, qui Moysi in rubo apparuisti; O Emmanuel, Exspectatio Gentium et Salvator earum, veni ad salvandum nos, Domine Deus noster '.
