[3] Several years prior to 1487, Noah travelled from Jerusalem to Fraydiss, near Ehden in Bsharri District on Mount Lebanon, to preach amongst the Maronites and provide teaching.
97 that he delivered a sermon at Mosul in the spring of 1492 (AG 1803), in which he condemned Nestorians for their opposition to the title of Theotokos (Syriac: yāldath ʾallāhā, "God-bearer") for Mary, mother of Jesus, and divergence in celebration of the Feast of the Annunciation.
[11][nb 2] He subsequently appealed to Qāsim ibn Jahāngīr, Aq Qoyunlu Sultan of Mardin, and the emir of Hasankeyf to be invested as Patriarch of all Sūryoyē to preclude rivals.
[17] In a letter, the Coptic Pope John XIII of Alexandria lent his support to Noah against Masʿūd, but advised conciliation and unity to preserve the integrity of the church.
[16][18] Through the arbitration of Sultan Qāsim ibn Jahāngīr of Mardin, the bishops of Tur Abdin and Noah were reconciled in 1495, and Masʿūd went into exile at a monastery at Kharput.
[20] An anonymous polemical text, entitled Treatise on the faith of the Syrians (Arabic: السريانية االمانة علي م), in which dyophysite Christianity is criticised, is ascribed to Noah.
