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.)

Etymology

Origin of baptism

First recorded in 1250–1300; Middle English, from Late Latin baptisma, from Greek bapt(ízein) “to immerse” ( see baptize) + -isma -ism; replacing Middle English bapteme, from Old French, from Late Latin, as above

Explanation

In the Christian church, baptism is a rite that symbolizes spiritual purification and rebirth. If you’ve had a baptism, it probably involved being dipped in water or having water sprinkled on you, lots of proud relatives, and hopefully cake afterwards. The word baptism can be traced to the Greek word baptismos, meaning “ceremonial washing.” This cleansing rite typically takes place when you’re a child and is often seen as an initiation into the church. Baptism can be used more broadly to describe other kinds of initiations as well. If you go through a difficult experience on your first day on the job, you could say that was your baptism as a customer service rep.
