Pope Pius XI, Ad Catholici Sacerdotii, Dec 20, 1935, Par. 34: “A great dignity [the confection of the Eucharist by the priest],” exclaims St. Lawrence Justinian, “but great too is the responsibility; placed high in the eyes of men they must also be lifted up to the peak of virtue before the eye of Him who seeth all; otherwise their elevation will be not to their merit but to their damnation.”
