Exorcism in the Catholic Church
According to the Vatican guidelines issued in 1999, “the person who claims to be possessed must be evaluated by doctors to rule out a mental or physical illness.” Most reported cases do not require an exorcism because twentieth-century Catholic officials regard genuine demonic possession as an extremely rare phenomenon that is easily confounded with natural mental disturbances. Despite that fact, every diocese is required to have at least one priest that is an exorcist, or is trained to perform exorcisms (17). As the demand for exorcisms has increased over the past few decades, the number of trained exorcists has also risen. In prior times, exorcists were kept fairly anonymous, and the performance of exorcisms remained a secret. Some exorcists attribute the rise in demand of exorcisms to the rise in drug abuse and violence, which leads to the suggestion that such things might work hand in hand. Many times a person just needs spiritual or medical help, especially if drugs or other addictions are present. The specially trained priest and medical professionals will be able to work together to address the patient, and be able to determine what type of illness the patient is suffering from. After the need of the person has been determined then the appropriate help will be met. In the circumstance of spiritual help, prayers may be offered, or the laying on of hands or a counseling session may be prescribed. The exorcist might not perform an exorcism if he does not know the person.
Excommunication
In the Catholic Church, excommunication is normally resolved by a declaration of repentance, profession of the Creed (if the offense involved heresy) and an Act of Faith, or renewal of obedience (if that was a relevant part of the offending act, i.e., an act of schism) by the excommunicated person and the lifting of the censure (absolution) by a priest or bishop empowered to do this. "The absolution can be in the internal (private) forum only, or also in the external (public) forum, depending on whether scandal would be given if a person were privately absolved and yet publicly considered unrepentant." Since excommunication excludes from reception of the sacraments, absolution from excommunication is required before absolution can be given from the sin that led to the censure. In many cases, the whole process takes place on a single occasion in the privacy of the confessional. For some more serious wrongdoings, absolution from excommunication is reserved to a bishop, another ordinary, or even the Pope. These can delegate a priest to act on their behalf.
