The Messianic Idea in Judaism
Belief in the eventual coming of the mashiach is a basic and fundamental part of traditional Judaism. It is part of Rambam’s13 Principles of Faith, the minimum requirements of Jewish belief. In the Shemoneh Esrei prayer, recited three times daily, we pray for all of the elements of the coming of the mashiach: ingathering of the exiles; restoration of the religious courts of justice; an end of wickedness, sin and heresy; reward to the righteous; rebuilding of Jerusalem; restoration of the line of King David; and restoration of Temple service.
Modern scholars suggest that the messianic concept was introduced later in the history of Judaism, during the age of the prophets. They note that the messianic concept is not explicitly mentioned anywhere in the Torah (the first five books of the Bible).
However, traditional Judaism maintains that the messianic idea has always been a part of Judaism. The mashiach is not mentioned explicitly in the Torah, because the Torah was written in terms that all people could understand, and the abstract concept of a distant, spiritual, future reward was beyond the comprehension of some people. However, the Torah contains several references to “the End of Days” (acharit ha-yamim), which is the time of the mashiach; thus, the concept of mashiach was known in the most ancient times.
The term “mashiach” literally means “the anointed one,” and refers to the ancient practice of anointing kings with oil when they took the throne. The mashiach is the one who will be anointed as king in the End of Days.
