In the Book of Acts, we read that some Jewish scribes, in attempting to exorcise a powerful demon in the name of Jesus, found that their attempts to use the name of Christ were futile, because they themselves had not embraced the Gospel and were not part of the Church. The Bible states: "And certain of the Jewish exorcists also, who went about, took in hand to call upon those who had wicked spirits the name of the Lord Jesus, saying, I adjure you by Jesus, whom Paul preaches. And there were certain [men], seven sons of Sceva, Jewish high priest, who were doing this. But the wicked spirit answering said to them, Jesus I know, and Paul I am acquainted with; but you, who are ye?" And the man in whom the wicked spirit was leaped upon them, and having mastered both, prevailed against them, so that they fled out of that house naked and wounded" (Acts 9:13-17). It is not enough to confess the Name of Jesus; one has to be incorporated into Christ, and to the Church, which is His Mystical Body. In more recent times, this truth has been exemplified in the marvelous case of Nicola Aubrey, a possessed girl in Vervins, Picardy in France. The events narrated below took place on the eighth of November, 1565, and lasted until the eighth of February, 1566 and were witnessed by thousands.
