First, you need to know the Jewish concept. The Hebrew word is 'moshiach'. Moshiach literally translates to 'annointed'. The title of moshiach was given to any person who was anointed with oil in their initiation into service of HaShem (The Creator) - kings, priest, prophets, and others. That being said, we've had hundreds of moshiachim, King David as a moshiach for example.
Christianity: Son of God (Messiah) Islam: Prophet Judaism: False messiah
Messiah.
The Messiah is probably as important as Moses the Prophet is.
Christians believe that Christ in the Messiah promised prophetically in the Old Testament. Judaism does not believe that Jesus in the Messiah.
Christianity believes that Jesus Christ is the promised messiah. Judaism is still waiting for the promised messiah.
In Judaism, the Messiah is believed to be a future savior figure who will bring peace and redemption to the world. In Christianity, the Messiah is seen as Jesus Christ, who is believed to have already come to Earth as the savior of humanity.
Judaism does not accept Yeshua (jesus) as messiah
In other religions, I don't know what their beliefs state. In Judaism, the answer is no. The messiah whom we await is to be fully human. See more on this topic towards the bottom of this linked page.
Catholics believe that Jesus was the Messiah and the Son of God, as well as the fulfiller of the Jewish religion. Jews believe that Jesus was not the Messiah, and they are still waiting for the Messiah to come.
The Christian concept of messiah does not exist in Judaism, regardless of Jewish sect. No Jew believes that Jesus was a moshiach.
Yes, Judaism held the promise of the Messiah and Christianity is the fullfillment of the Messiah through savior Jesus Christ.
