Input (English): This practice had an analog in the cult of Cybele's practice of taurobolium, and this practice is advocated by the Right Ginza in Mandeism, which follows this action with a sacred meal. A reference to this practice "for the dead," is contained in 1 Corinthians 15:29, in which it is asked "if there is no resurrection, what will those do," to whom this has happened. That practice may originate in the rituals of the Orphic cult, which carried out this action to prepare their dead for the underworld. According to the Arians and the Donatists, this action was only efficacious if performed by someone who was of pure intention and belonged to the church, while leaders like Conrad Grebel and Felix Mantz argued that only an adult could undergo this ritual and denied its usefulness to infants. This practice is generally considered the first sacrament in Catholicism. Taking its name from the Greek for "to immerse," for ten points, identify this action which was performed for Jesus by John, and which involves annointment with water, symbolizing entry to the faith.
