The Refutation of All Heresies

And this (Marcus), infusing (the aforesaid) mixture into a smaller cup, was in the habit of delivering it to a woman to offer up the Eucharistic prayer, while he himself stood by, and held (in his hand) another empty (chalice) larger than that. And after his female dupe had pronounced the sentence of Consecration, having received (the cup from her), he proceeded to infuse (its contents) into the larger (chalice), and, pouring them frequently from one cup to the other, was accustomed at the same time to utter the following invocation: “Grant that the inconceivable and ineffable Grace which existed prior to the universe, may fill your inner man, and make to abound in you the knowledge of this (grace), as She disseminates the seed of the mustard-tree upon the good soil.”

And simultaneously pronouncing some such words as these, and astonishing both his female dupe and those that are present, he was regarded as one performing a miracle; while the larger was being filled from the smaller chalice, in such a way as that (the contents), being superabundant, flowed over. And the contrivance of this (juggler) we have likewise explained in the aforesaid (fourth) book, where we have proved that very many drugs, when mingled in this way with liquid substances, are endued with the quality of yielding augmentation, more particularly when diluted in wine.

Now, when (one of these impostors) previously smears, in a clandestine manner, an empty cup with any one of these drugs, and shows it (to the spectators) as if it contained nothing, by infusing into it (the contents) from the other cup, and pouring them back again, the drug, as it is of a flatulent nature, is dissolved by being blended with the moist substance. And the effect of this was, that a superabundance of the mixture ensued, and was so far augmented, that what was infused was put in motion, such being the nature of the drug.

And if one stow away (the chalice) when it has been filled, (what has been poured into it) will after no long time return to its natural dimensions, inasmuch as the potency of the drug becomes extinct by reason of the continuance of moisture. Wherefore he was in the habit of hurriedly presenting the cup to those present, to drink; but they, horrified at the same time, and eager (to taste the contents of the cup), proceeded to drink (the mixture), as if it were something divine, and devised by the Deity.
