dominion, it is called exorcism.
Liberation
In a simple form, exorcism is practiced during the celebration of Baptism. Since Baptism signifies liberation from sin and its instigator, the Devil, an exorcism is pronounced over the candidate. The candidate is anointed with the oil of catechumens, or the celebrant imposes hands, and the candidate explicitly renounces Satan.
The solemn exorcism, called “great exorcism,” can only be performed by a priest with the permission of the Bishop. It is necessary to proceed with prudence, strictly observing the rules established by the Church. It is important, therefore, to ensure, before performing the exorcism, whether it is a presence of the evil one or a mental illness.
