On his way to the mediation, Nerses stopped at Mamistra, where he met the Byzantine governor Alexios Axouch and discussed the strained relations between the Armenian and Greek churches since the Greek Orthodox declared the Armenian Church and the Jacobite Church heretics in 1140. Axouch was sufficiently impressed with this discussion to urge Nerses to write an exposition of the Armenian faith which Axouch could then forward to the emperor in Constantinople. Nerses did so, stressing in his letter that, as both the Armenian and Greek churches accepted the statements of the First Council of Ephesus, there was no clear reason for them not to be in agreement, making no polemical statements about the later Council of Chalcedon and its Confession.
