The Catholic archbishop of Washington has removed a well-known priest who said UFO sightings were the work of demons. The archdiocese says the priest is an exorcist and they will be cutting ties with the Washington-based nonprofit he heads, the St. Michael Center for Spiritual Renewal. The archbishop says the priest's public statements linking UFOs to a demonic presence and the center’s recent use of social media "gravely undermine the Church’s very precise teaching on the devil, demons and exorcism.”
