The Red Pentecost is a fictional religious practice of the Cainite Heresy, in the medieval setting of White Wolf Game Studio's role-playing game Vampire: The Dark Ages. The Red Pentecost mimicks the Christian Pentecost, in which the apostles were filled with the Holy Spirit and performed miraculous actions. In the case of the Red Pentecost, the Holy Spirit is replaced by the Beast that lies within all human beings, who is freed and allowed to take control.
