Q. 1. What is a Black Mass?
A. 1. In the Roman Catholic Church, a Black Mass is a Requiem Mass during which the priest wears black vestments. The wearing of black vestments is recommended for (a) All Souls Day and (b) masses for the dead (Requiem Masses), except for baptized children who've died before the age of reason.
In the United States, many priests prefer not to use the color black. That explains why it has not been seen for years. Although this is the case, the color black continues to be a valid liturgical color.
Nowadays, the term "Black Masses" is more commonly used to represent the blasphamous imitation of the true Mass that is performed by Satanic cults. The ritual is an inversion of the Traditional Latin Mass that is celebrated by the Roman Catholic Church. The history of such rituals is unclear before the modern era.
The Black Mass was allegedly celebrated during the Witches' Sabbath. Its purpose is to mock God and worship the devil. It is alleged that the rite involves human sacrifice as well as obscenity and blasphemy of horrific proportions.
