Yohannan VIII Hormizd
Meanwhile, the Vatican reconsidered the condemnation of Yohannan Hormizd in the light of fresh information, and on 25 November 1826 publicly absolved him. At the same time, to restore the peace of the Chaldean Church, it urged the 66-year-old former patriarchal administrator to renounce his claims to the archdiocese of Mosul and to retire quietly. Yohannan, vindicated by the Vatican's absolution and supported by the local civil authorities, stubbornly refused to retire. Instead, he fought back against his opponents. In 1827, during the absence of the superior Gabriel Dambo in Rome, a number of monks in the monastery of Rabban Hormizd rebelled against its administrator Yohannan Gwera, who enjoyed the support of the metropolitan Joseph Audo. Yohannan Hormizd upheld the rebels, and was also able to have Basil Asmar expelled from Telkepe, forcing him to take refuge in Amid.
Hormizd III
The Arsacid ruler of Caucasian Albania, Vache II (), who was the nephew of the two brothers through his mother, and had been forced to convert to Zoroastrianism by Yazdegerd II, took advantage of the dispute by declaring independence and reverting to Christianity. Peroz later went to the domains of the Hephthalite monarch, who agreed to him support with soldiers in his struggle for the throne. In 459, Peroz, with Hephthalite and Mihranid assistance, led an army against Hormizd and defeated him. According to some sources, Hormizd was pardoned and spared by his brother. However, this is most likely a legend, which is disproved by other sources, that states Peroz had Hormizd and three members of his family killed. No coins minted during Hormizd's reign has been found.
