Messianism

Nature

Messianism is the belief in the advent of a messiah who acts as the savior of a group of people. Messianism originated as a Zoroastrian religious belief and followed to Abrahamic religions, but other religions also have messianism-related concepts. Religions with a messiah concept include Judaism (Mashiach), Christianity (Christ), Islam (Isa Masih), Druze faith (Jesus and Hamza ibn Ali), Zoroastrianism (Saoshyant), Buddhism (Maitreya), Taoism (Li Hong), and Bábism (He whom God shall make manifest).

In Judaism, the messiah will be a future Jewish king from the line of David and redeemer of the Jewish people and humanity. In Christianity, Jesus is the messiah, the savior, the redeemer, and God. In Islam, Jesus was a prophet and the messiah of the Jewish people who will return in the end times.

Claim 
In this confusion (of conflicts between generations) the temptation becomes stronger to risk being swept away towards types of messianism which give promises but create illusions. The resulting dangers are patent: violent popular reactions, agitation towards insurrection, and a drifting towards totalitarian ideologies. Such are the data of the problem. Its seriousness is evident to all. (Papal Encyclical, Populorum Progressio, 26 Mar 1967).
