The satanic missal “Missale Satanae” contains a detailed description of the preparation and performance of the satanic rituals of the Black Mass and Satanic exorcism according to the impious rite of Ecclesia Luciferi System. In the briefest of terms, the content of the Missale Satanae was based on an analysis of the states of religious ecstasy found in various cults around the world and on Western Christian religious and ecclesiastical ritual writings created in the 16th century, but based on even earlier rituals.
