Teacher of Righteousness
Somewhat along these lines is the proposal that Hyrcanus II was the Teacher of Righteousness. This was proposed in 2013 by Gregory Doudna. Hyrcanus was the high priest of the Temple from 76 to 67 BCE and from 63 to 40 BCE. According to Doudna, Hyrcanus II’s sectarian orientation is now generally understood to have been Sadducee.
