Exorcism
In Catholic practice the person performing the exorcism, known as an exorcist, is an ordained priest. The exorcist recites prayers according to the rubrics of the rite, and may make use of religious materials such as icons and sacramentals. The exorcist invokes God—specifically the Name of Jesus—as well as members of the Church Triumphant and the Archangel Michael to intervene with the exorcism. According to Catholic understanding, several weekly exorcisms over many years are sometimes required to expel a deeply entrenched demon.
Giancarlo Gramolazzo
He was dedicated during 30 years to exorcism, becoming president of the International Association of Exorcists, founded in 1990 by father Gabriele Amorth (1925–2016), who later remained its honourable president and 5 other priests.
Father Gramolazzo has over thirty years experience as an exorcist.
He helped Father Gabriele Amorth in a 1999 exorcism of a nineteen years old woman. The next day the same woman who appeared at the Vatican underwent another exorcism performed by Pope John Paul II.
