Certain Protestant writers, even down to our own times, have, however, insisted that, at any rate inwardly, the devil had sought to reduce Luther to despair on account of his celebration of Mass as a Catholic; that the spirit of darkness had attached so much importance to the suppression of the Gospel, that he attempted to disquiet Luther with such self-reproaches.[432] It is true Luther once says that the devil reproached him with his “misdeeds, for instance, with the sacrifice of the Mass,” and other Catholic practices of which he had formerly been guilty.[433] On other occasions, however, he quite absolves the devil of any change concerning the Mass. He says, e.g.: “The devil is such a miscreant that he does not reproach me with my great and awful crimes such as the celebration of Mass,”[434] etc. Thus he had persuaded himself quite independently of the devil that the Mass was a grievous crime. We have, in fact, in Luther’s statements concerning his inward experiences a crying instance of his changeableness. We shall return below to his self-reproach on account of his celebration of Mass (see section 4). _Possession and Exorcism_ We may conclude our examination of diabolical apparitions by some statements concerning the exorcisms Luther undertook and his treatment of cases of possession. His first followers believed he had been successful in 1545 in driving out Satan in the case of a person possessed. The testimony of two witnesses of the incident must here come under consideration, both young men who were present on the occasion, viz. Sebastian Fröschel, Deacon at Wittenberg, and Frederick Staphylus, a man of learning who afterwards abandoned Lutheranism and became Superintendent of the University of Ingolstadt.[435] The latter knows nothing of any success having attended Luther’s efforts, whereas the former boasts that such was the case, though he somewhat invalidates his testimony by saying nothing of the embarrassing situation in which Luther found himself at the close of the scene. According to both accounts the incident was more or less as follows: A girl of eighteen from Ossitz in the neighbourhood of Meissen who was said to be possessed was brought one Tuesday to Luther, and, while at his bidding reciting the Creed, was “torn” by the devil as soon as she reached the words “and in Jesus Christ.” Luther hesitated at first to set about the work of liberation and expressed his contempt for the devil whom he “well knew.” The next day, after his sermon, he caused the “possessed” girl to be brought to him in the sacristy of the parish church of Wittenberg by the above-mentioned Fröschel.
