Chaldean Catholic Archeparchy of Kirkuk-Sulaimaniya
The foundation of the Chaldean Catholic diocese of Kirkuk has been attributed to Yohannan VIII Hormizd, who was recognised by the Vatican as patriarchal administrator of the patriarch of Babylon in 1780 and, after five decades of disputes and confrontations, as patriarch in 1830. According to the Chaldean Catholic priest Joseph Tfinkdji, Yohannan Hormizd visited the town of Kirkuk in 1789 while travelling from Mosul to Baghdad, and converted its Church of the East community to Catholicism. He is said to have consecrated a Chaldean metropolitan for Kirkuk, Mar Abraham, who resided in Aïnqawa during his reign, and died between 1821 and 1824. The source for this assertion is not clear. Abraham is not mentioned by any other source, and as Yohannan Hormizd himself (then considered by the Vatican to be merely metropolitan of Mosul) is styled 'metropolitan of Kirkuk' in a colophon of 1798, the Kirkuk region would seem to have been part of the diocese of Mosul at this period.
Mar Hormizd Syro-Malabar Church, Angamaly
In 1578, as a response to the requests made on the part of the Jesuit missionaries who had been working in Angamaly and in the other centres of the Christians of St. Thomas, the pope sent plenary indulgences to the Church of Rabban Hormizd which the faithful could obtain four times a year for 25 years from the year of the election of the Metropolitan Mar Abraham. The indulgences covered two feasts of the Patron Rabban Hormizd that fell on the fifteenth day after Easter (Monday) and on the first of September. On 15 August 1579, as requested by Mar Abraham, the Jesuits laid the foundation stone of a new Cathedral Rabban Hormizd in the same place that was chosen by the Metropolitan.
