Teacher of Righteousness
One theory initially advocated by Jerome Murphy-O'Connor and subsequently by Stegemann is that the Teacher of Righteousness served as High Priest but was subsequently ousted by Jonathan Apphus. In 1 Maccabees, no High Priest is named for the period from the death of Alcimus in 159 BCE to the claiming of the position of High Priest by Jonathan on the authority of Alexander Balas in 152 BCE (1 Macc 10:18–20). From this it could be concluded that there was no High Priest for these years, and indeed Josephus, drawing heavily on 1 Maccabees at this point in his history, comes to that conclusion (Ant. 20.237). It is improbable, however, that the office remained completely vacant for these years. Stegemann suggests that the reason that nothing is said in 1 Maccabees about a High Priest between Alcimus and Jonathan was apologetic: to conceal the fact that the Hasmoneans obtained the High Priesthood by usurping it from its rightful holder, the Teacher of Righteousness. Alvar Ellegård follows this line and argues that the Teacher of Righteousness was not only the leader of the Essenes at Qumran, but was also considered something of a precursor to Jesus Christ about 150 years before the time of the Gospels.
