By Joseph Pronechen, EWTN News - Due to the ever-increasing de-Christianization of Western society, the rise in occult practices even among Christians, and the poor state of Christian religious formation, the need for deliverance and exorcism ministry has increased dramatically. Since I have worked closely with the Dicastery for the Causes of Saints and served as an exorcist in North America and Europe, the Holy See asked me to undertake a catechesis about the Church’s teaching regarding the demonic, spiritual warfare and exorcism.
