In Christianity, deliverance ministry refers to the activity of cleansing a person of demons and evil spirits in order to address problems manifesting in their life as a result of the presence of said entities and the root causes of their authority to oppress the person. Adherents to this theological concept attribute physical, psychological, spiritual and emotional problems that people suffer to the activities of the oppressing spirits following the example of Jesus Christ given in the gospel. The practices and many of the underlying beliefs of these ministries are not accepted by all Christians.
Deliverance ministries focus on casting out the spirit or spirits believed to cause an affliction. The method of casting out varies. Some adherents directly recite Biblical examples in prayer intended to command a demon to depart an afflicted person, and do not believe an ordained clergy is required to perform the deliverance.
Ministries also organize the removal from homes of items that are believed to harbor demons, including fantasy or horror novels, and artworks / artifacts depicting pagan gods. Members are instructed to burn items that are related to idol worship, "demon drawing" symbols and music that summons demons.
Although Rev. Don Jeffrey, An exorcist in Arizona www.theforgottenministry.org states that any and all of these objects should be exorcised of any evil spirits and blessed before burning them or sending them to the dump. An Ouija board is a perfect example of this. It acts like a gateway for the demonic and must be exorcised and blessed, the gate must be closed before it is destroyed.
For some Christians, deliverance ministries are activities carried out by specialist individuals like Bishop Larry Gaiters and Rev Vincent Bauhaus or groups aimed at solving problems related to demons and spirits, especially possession of the body and soul, but not the spirit as ministries like Ellel Ministries International, Don Dickerman Ministries and Neil T. Anderson explicitly teach that a Christian can not have demons in their spirit because the Holy Spirit lives there, though they can have demons in their body or soul due to inner emotional wounds, sexual abuse, or Satanic ritual abuse. This is usually known as partial possession or demonic infestation, as opposed to outside demonic oppression which does not reside in any of the 3 parts of a person: body, soul, spirit.
