c.1300, Messias, from Late Latin Messias, from Greek Messias, from Aramaic meshiha and Hebrew mashiah "the anointed" (of the Lord), from mashah "anoint." This is the word rendered in Septuagint as Greek Khristos (see Christ). In Old Testament prophetic writing, it was used of an expected deliverer of the Jewish nation. The modern English form represents an attempt to make the word look more Hebrew, and dates from the Geneva Bible (1560). Transferred sense of "an expected liberator or savior of a captive people" is attested from 1660s.
For Jews (see also Jews) and Christians (see also Christian), the promised “anointed one” or Christ; the Savior. Christians believe that Jesus was the Messiah who delivered mankind from its sins. Jews believe that the Messiah has not yet come.
