Father Jeffrey Steffon, in his book entitled "Satanism: Is It Real?", reminds us that, "Deliverance prayer is one of the oldest traditions of the Catholic Church. In the Our Father we pray, 'Deliver us from evil.' That prayer is a prayer for deliverance. Christians are able to pray for deliverance from evil spirits because Jesus gave them that power. In Luke 10 Jesus commissioned the seventy disciples to spread the kingdom of God. In this action Jesus gave them authority over demonic spirits. The seventy, upon their return to Jesus, exclaimed, 'Even the demons are subject to us in your name!'
Though Jesus gave His followers such power, it is up to individual Christians to use it...Deliverance prayer is not exorcism. There are two forms of exorcism: solemn and private. Solemn exorcism is a liturgical rite and public action of the Catholic Church. Solemn exorcism is performed only by an official delegate of the Bishop. Private exorcism is not a public, liturgical rite. The terms private (or simple) exorcism and deliverance refer to the same action. This style of prayer is used to curb the influence of Satan in the lives of Christians. Whereas in solemn exorcism only the delegate of the Bishop may perform the exorcism, any Christian can say the deliverance prayer.
Deliverance prayer is said in the name of the person of Jesus. Solemn exorcism is prayed in the name of Jesus and the whole Catholic Church. It would seem logical that a priest, by the power of the sacrament of Holy Orders, has a greater commission than the laity to pray the deliverance prayer. This is not always the case, however, because this prayer is a charism. God can give charisms to whomever He chooses..." (pp. 174-175).
The Congregation for the Doctrine of the Faith, responding to certain questionable activities, published a statement which said (in part):
..the Bishops are requested to watch that, even in cases where a true diabolical possession is excluded, those who lack the proper permission do not supervise or direct the assemblies in which prayers are used to obtain a releasing, in the course of which the devils are disturbed and their identities sought. However, the declaration of these norms by no means should keep the faithful from praying to be delivered from evil, as Jesus taught. Moreover, the Bishops will be able to use any given opportunity to recall what the tradition of the Church teaches about the role played by the sacraments and the intervention of the Blessed Virgin Mary, of the Angels, and of the Saints in the spiritual struggle of Christians against evil spirits."
What are we waiting for then?
