Question: Where did the practice of baptism come from?

context: The is thought to have been compiled early in the 2nd century, and initially appended to the gospel by the middle of that century. It says that those who believe and are baptized will be saved, "but he who does not believe will be condemned." Mark's gospel does not "explicitly" state that baptized persons who believe will be saved from the "wrath to come," the wrath to which John the Baptist refers in Matthew's gospel, but readers can infer that being "condemned" includes the "wrath to come".

Answer: John the Baptist, who is considered a forerunner to Christianity, used baptism as the central sacrament of his messianic movement. Christians consider Jesus to have instituted the sacrament of baptism. Although the term "baptism" is not used to describe the Jewish rituals, the purification rites in Halakha Jewish law and tradition, called tvilah or tevilah, a full body immersion, have some similarity to baptism, and the two have been linked. The practice of baptism originated in the Middle East.
