 While his relations with the Vatican were cooling, Yohannan Hormizd also had to deal with the opposition of his cousin Ishoyahb, who continued to assert that he was the rightful patriarch.After Yohannan's irregular election in 1780 Ishoyahb withdrew to Amadiya, whose governor Isma'il gave him 'the Nestorian dioceses of the mountain' to govern.He made another Catholic profession of faith on 7 April 1783 in an attempt to regain the sympathies of the missionaries, and to preserve the patriarchate within his family consecrated his nephew Hnanisho metropolitan in 1784.
