On the Vigil of the Epiphany, the Rite of Exorcism and Blessing of Epiphany Water (All in Latin!) was offered. It is a very beautiful and lengthy Rite. It begins with the Litany of Saints, with a couple special petitions about the blessing of the water to follow. Satan and the demons are then driven from the place with a mighty prayer.
According to some Exorcists, this rite of the blessing of the waters, with
its extraordinarily powerful prayers of exorcism, renders Epiphany Water more spiritually potent than ‘ordinary’ holy water (also, exorcised salt is part of the ritual and is used to ‘make’ Epiphany water).
