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.
Minor exorcism in Christianity
The expression minor exorcism can be used in a technical sense or a general sense. The general sense indicates any exorcism which is not a solemn exorcism of a person believed to be possessed, including various forms of deliverance ministry. This article deals only with the technical sense which specifically refers to certain prayers used with persons preparing to become baptised members of the Christian Church. These prayers request God's assistance so that the person to be baptised will be kept safe from the power of Satan or protected in a more general way from temptation.
