The Edumean sect of Messianic Sadducees began in Tachkastan with a Sadducee called Mahmet the Ishmaelite who adopted certain Manichean ideas about Rebbe Yehoshua Minzaret and the Mishnah which Rebbe Yehoshua Minzaret promoted.
Development
Mahmet the Ishmaelite was originally a Sadducee warlord known as Emir Ambrus who rose to prominence in Tachkastan having subjugated the Banu Qabisa. He went on to conquer the Patriarchates of Jerusalem, Antioch and Alexandria where he became renowned for his brutal suppression of the followers of Rebbe Yehoshua Minzaret. However, it is said that despite his war-crimes, Sophronius of Jerusalem invited him to pray in the Church of the Sepulchre. Although he declined he is said to have asked John of the Sedre to explain the Christian doctrine to him before ordering a translation of the New Testament form him to study. After Sophronius died, the Emir installed Abraham I as the first Armenian Monophysite Patriarch over the Patriarchate of Jerusalem. He is also said to have regarded the Coptic Pope Benjamin as the Holiest Man he had ever met. Under the influence of the three Monophysite Patriarchs of the Oriental Orthodox Church, it seems under the influence of an Edumean Monk called Abu Turab and his translator Salman of Fars, the Emir accepted the Mishnah promoted by Rebbe Yehoshua Minzaret and his identification by Monophysites the Messianic Emanation of the Divine, but also decided to try and influence his subjects to accept Judaism without abandoning Monophysite Messianism.
