Quote:This figure [...] rose to prominence during the reign of Alexander Jannaeus, and had been a priest and confidant to the king. However, he became dissatisfied with the religious sects in Jerusalem, and in reaction, founded a "crisis cult". While amassing a following, the Teacher (and his followers) claimed he was the fulfillment of various Biblical prophecies, with an emphasis on those found in Isaiah. The Teacher was eventually killed by the religious leadership in Jerusalem, and his followers hailed him as messianic figure who had been exalted to the presence of God's throne. They then anticipated that the Teacher would return to judge the wicked and lead the righteous into a golden age, and that it would take place within the next forty years.Sounds familiar?
