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.
Exorcism
Historically, Taoist exorcisms include chanting, physical movements, and praying as a way to drive away the spirit. Rituals such as these occur during festivals. Rituals such as these are considered of low order during these festivals. They are more for entertainment than a necessity during festivals.
