The Messianic Age is a theological term referring to a future time of universal peace and brotherhood on the earth, without crime, war and poverty. Many Abrahamic religions believe that there will be such an age; some refer to it as the consummate "kingdom of God", "paradise", Peaceable Kingdom, or the "world to come".
In the context of "Messianic Age", the earliest meaning of the word "messianic" is derived from notion of Yemot HaMashiach meaning "the days of the messiah", that is, the Jewish Messiah. Messiah derives from Hebrew, meaning "the anointed one". Originally the "anointed one" referred to Aaron and his descendants, the Kohanim. Following the establishment of the kingdom of Saul, it could also refer to a king who was anointed with holy anointing oil as part of what might be understood to be his coronation ceremony.
Eschatology is an area of religious scholarship that deals with prophecies about "the end of the current age" of human civilization.
According to Jewish tradition, the Messianic Era will be one of global peace and harmony, an era free of strife and hardship, and one conducive to the furtherment of the knowledge of the Creator. The theme of the Jewish Messiah ushering in an era of global peace is encapsulated in two of the most famous scriptural passages from the Book of Isaiah:
They shall beat their swords into plowshares and their spears into pruning hooks; nation will not lift sword against nation and they will no longer study warfare. (Isaiah 2:4)
