Yohannan VIII Hormizd
For the next eight years Yohannan Hormizd seemed to justify the hopes placed in him. He lived on amicable terms with the Catholic missionaries and devoted his energies to the conversion to Catholicism of the villages under his authority. In May 1790, on the advice of the missionaries, he consecrated his nephew Shemon metropolitan, and in August of the same year sent him to the Zibar district, where he converted the Nestorian villages of Arena and Barzane. The following year he sent Shemon to Mengesh in the Sapna district, where he was equally successful. The high point of this honeymoon period came in February 1791, when the Vatican appointed him patriarchal administrator of the Amid patriarchate, recalling Lazar Hindi to Rome to leave him a free hand. This appointment led to strenuous protests from Lazar Hindi, his vicar-general Joseph Attar and the clergy of Amid, and on 3 February 1793 Yohannan Hormizd's appointment was rescinded.

Hormizd also declined the requests of the Zoroastrian priesthood to persecute the Christians. He did not like the Zoroastrian priesthood, and therefore killed a great deal of them, including the chief priest ("mowbed") himself. Furthermore, Hormizd greatly reduced the payment of the military by 10 percent and massacred many powerful and prominent members of the elite, including the famous Karenid "vizier" of his father, Bozorgmehr, the latter's brother Simah-i Burzin; the Mihranid Izadgushasp; the "spahbed" ("army chief") Bahram-i Mah Adhar, and the Ispahbudhan Shapur, who was the father of Vistahm and Vinduyih. According to the medieval Persian historian al-Tabari, Hormizd is said to have ordered the death of 13,600 nobles and religious members.
