baptism Cultural  

1. The ceremony of initiation into Christianity; in most Christian churches, it is considered a sacrament. Persons baptized either have water poured on them or are immersed in water; some groups of Christians (see also Christian) insist on immersion. The effect of baptism, in Christian belief, is to cleanse persons of their sins, so that they are born into a new life with Jesus. Most churches baptize members when they are infants, but some groups, like the Baptists, insist on adult baptism. Jesus himself was baptized. (See John the Baptist.)
