The Messiah is a term in Judaism and Christianity though the two religions have different concepts about this.
Christianity[]
Christians claim that Jesus was the Messiah, the son of God, born to redeem the world from Hell and bring sinners to heaven. Most Christians see Jesus as one part of the Trinity.
Judaism[]
Jews focus on the messiah as a human being who has not yet come and who will achieve things in this world. According to Judaism the true Messiah must
*Be an observant Jewish man descended from the house of King David
Furthermore, Jews believe that God gave a complete and everlasting covenant to his followers in the form of the Tanakh while Christians claim that Jesus brought a new covenant. The two views are incompatible.
