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.
Johannes Hymonides
At the instance of Pope John VIII (872-82), John wrote a life of St. Gregory the Great, making use of the works of this pope and above all of extracts made at an earlier date from the pope's letters in the archives of the Roman Church. The work is divided into four books: in the first he gives an account of the life of Gregory up to the time of his pontificate; in the second, of his activities as pope; in the third, of his teachings; and in the fourth, of his progress in perfection. The life was most recently edited by the Maurists. For John VIII, John also composed in 876 an adaptation of the Cena Cypriani.
