exorcism

352. What is an exorcism?
1673
When the Church asks with its authority in the name of Jesus that a person or object be protected against the power of the Evil One and withdrawn from his dominion, it is called an exorcism. This is done in ordinary form in the rite of Baptism. A solemn exorcism, called a major exorcism, can be performed only by a priest authorized by the bishop.
