Exorcism
In Catholic practice the person performing the exorcism, known as an exorcist, is an ordained priest. The exorcist recites prayers according to the rubrics of the rite, and may make use of religious materials such as icons and sacramentals. The exorcist invokes God—specifically the Name of Jesus—as well as members of the Church Triumphant and the Archangel Michael to intervene with the exorcism. According to Catholic understanding, several weekly exorcisms over many years are sometimes required to expel a deeply entrenched demon.
Anneliese Michel
The trial started on 30 March 1978 in the district court and drew intense interest. Before the court, doctors testified that Michel was not possessed, stating that this was a psychological effect because of her strict religious upbringing and her epilepsy, but the doctor Richard Roth, who was asked for medical help by Alt, allegedly told her during the exorcism, that "there is no injection against the devil, Anneliese". Schmidt-Leichner said that the exorcism was legal and that the German constitution protected citizens in the unrestricted exercise of their religious beliefs. The defense played tapes recorded at the exorcism sessions, sometimes featuring what was claimed to be "demons arguing", to assert their claim that Michel was possessed. Both priests said the demons identified themselves as Lucifer, Cain, Judas Iscariot, Hitler, and Nero among others; they further said that she was finally freed because of the exorcism just before her death.
