“This is the example. There was during my lifetime in the town of Madaura, the birthplace of the philosopher Apuleius, a witch who was able to attract men to her chamber by burning a few of their hairs along with certain herbs upon her tripod, pronouncing at the same time certain words. Now one day when she wished by this means to gain the love of a young man, she was deceived by her maid, and instead of the young man’s hairs, she burned some hairs pulled from a leather bottle, made out of a goatskin that hung in a tavern. During the night the leather bottle, full of wine, capered through the town up to the witch’s door. This fact is undoubted. And in sacraments as in enchantments it is the form which operates. The effect of a divine formula cannot be less in power and extent than the effect of an infernal formula.” Having spoken in this fashion the great St. Augustine sat down amidst applause. One of the blessed, of an advanced age and having a melancholy appearance, asked permission to speak. No one knew him. His name was Probus, and he was not enrolled in the canon of the saints. “I beg the company’s pardon,” said he, “I have no halo, and I gained eternal blessedness without any eminent distinction. But after what the great St. Augustine has just told you I believe it right to impart a cruel experience, which I had, relative to the conditions necessary for the validity of a sacrament. The bishop of Hippo is indeed right in what he said. A sacrament depends on the form; its virtue is in its form; its vice is in its form. Listen, confessors and pontiffs, to my woeful story. I was a priest in Rome under the rule of the Emperor Gordianus. Without desiring to recommend myself to you for any special merit, I may say that I exercised my priesthood with piety and zeal. For forty years I served the church of St. Modestus-beyond-the-Walls. My habits were regular. Every Saturday I went to a tavern-keeper called Barjas, who dwelt with his wine-jars under the Porta Capena, and from him I bought the wine that I consecrated daily throughout the week. During that long space of time I never failed for a single morning to consecrate the holy sacrifice of the mass. However, I had no joy, and it was with a heart oppressed by sorrow that, on the steps of the altar I used to ask, ‘Why art thou so heavy, O my soul, and why art thou so disquieted within me?’ The faithful whom I invited to the holy table gave me cause for affliction, for having, so to speak, the Host that I administered still upon their tongues, they fell again into sin just as if the sacrament had been without power or efficacy. At last I reached the end of my earthly trials, and failing asleep in the Lord, I awoke in this abode of the elect. I learned then from the mouth of the angel who brought me here, that Barjas, the tavern-keeper of the Porta Capena, had sold for wine a decoction of roots and barks in which there was not a single drop of the juice of the grape. I had been unable to
