About "Amadiya (Chaldean Diocese)"
=== Background ===
There were three main concentrations of East Syrian villages in the ʿAmadiya region: in the Sapna valley to the west of ʿAmadiya, in the Tigris plain around Dohuk, and in the Shemkan district, around the valley of the Gomel river. Before the fourteenth century the Sapna valley was part of the diocese of Dasen and Beth Ture ('the mountains'), which lay to the north of Marga and also covered the Berwari region and the Zibar and Lower Tiyari districts. The villages in the Dohuk district were included in the East Syrian diocese of Beth Nuhadra, whose bishops resided in the small town of Tel Hesh near Alqosh, and those in the Gomel valley in the diocese of Marga, centred on the ʿAqra region. The last-known bishops of Beth Nuhadra and Dasen, Ishoʿyahb and Mattai, were present at the consecrations of Makkikha II in 1257 and Yahballaha III in 1281 respectively, and it is unclear when either diocese came to an end.
No bishops of the ʿAmadiya region are known from the fourteenth and fifteenth centuries. After the schism of 1552 the region remained loyal to the Nestorian patriarch Shemʿon VII Ishoʿyahb, and his opponent Yohannan Sulaqa, the first Chaldean patriarch, was martyred in 1554 after an attempt to win over ʿAmadiya's East Syrian community. Thereafter the region seems to have been claimed by both patriarchates for some decades. A metropolitan ʿAbdishoʿ of 'Koma', probably the Sapna village of Komane with its recently-revived monastery of Mar ʿAbdishoʿ of Kom, was among the signatories of a letter of 1580 from Shemʿon IX Denha to pope Gregory XIII, and the Dasen district was claimed by the Qochanes patriarch Shemʿon XI in 1653. On the other hand, a bishop Abraham of Beth Ture ('the mountains') is mentioned among the hierarchy of Eliya VIII in the report of 1610. Given its proximity to Alqosh, it would be surprising to find the region under the influence of the Qudshanis patriarchs, and the surviving manuscripts copied for the Dohuk, Sapna and Shemkan villages (some originating from Gazarta but the majority from Alqosh) invariably mention patriarchs of the Eliya line. By the end of the eighteenth century the Mosul patriarchate had a diocese of ʿAmadiya for the region.
The patriarch Eliya XIII Ishoʿyahb consecrated his nephew Hnanishoʿ metropolitan of ʿAmadiya in September 1784 after his withdrawal to ʿAmadiya, with the intention of preserving the patriarchal succession within his family. Hnanishoʿ made a Catholic profession of faith in 1795, but was felt by the Latin missionaries to be insincere. In 1801 the Vatican informed them that he could not be received as a bishop in the Catholic Church without 'manifest signs of penitence'. Shortly afterwards in the same year Hnanishoʿ openly defied the Vatican, consecrating the priest Peter Shawriz metropolitan of Seert.
Hnanishoʿ seems to have become reconciled with Yohannan Hormizd after the death of Eliya XIII Ishoʿyahb in 1804, as in 1808 he was living in his household in Alqosh. He was 'senior to Yohannan, and governed the diocese of ʿAmadiya, but all the same could do nothing without the approval of the metropolitan Yohannan'. Although he sympathised with Gabriel Dambo's monastic order, his dependence on Yohannan Hormizd occasionally forced him to act against his better judgement. In 1808 he asserted himself by delivering the monastery of Rabban Hormizd to Gabriel Dambo in defiance of Yohannan Hormizd's wishes. In 1811, however, on Yohannan Hormizd's instructions, he 'became a Nestorian at ʿAmadiya' and expelled Dambo and his monks from the monastery with the assistance of the civil authorities. In 1813 he fell mortally ill, and made amends for his harsh treatment of the monks on his deathbed by returning the keys of the monastery to them. He died shortly afterwards and was buried in the monastery of Rabban Hormizd, 'among the tombs of the patriarchs of the Nestorians'.
=== Chaldean bishops of Amadiya ===
Some years earlier a Catholic diocese had been established in the region with the consecration by Yohannan Hormizd of his nephew Mattai Shemʿon for ʿAmadiya on 5 May 1790. Shemʿon, originally named Yohannan, was the son of Yohannan's brother the priest Giwargis, and appears to have been consecrated on the suggestion of the missionary Maurizio Cherzoni. There is no need to doubt the sincerity of Yohannan Hormizd's commitment to the Catholic faith at this period, but the appointment was of course also directed against his rival Eliya XIII Ishoʿyahb. After his consecration Shemʿon made a determined effort to convert a number of villages in the Sapna plain and the Zibar district to Catholicism. He was killed by brigands not far from the Great Zab in 1811.
Basil Asmar of Telkepe, a monk of the monastery of Rabban Hormizd, was consecrated for ʿAmadiya at Amid by the patriarchal administrator Augustine Hindi in April 1824, but seems to have had no contact with his diocese. He resided in his home village of Telkepe until 1827, apparently in fear of the governor of ʿAmadiya, known to be a friend of Yohannan Hormizd, and in 1827 fled to Amid, becoming its metropolitan in 1828.
Basil Asmar was succeeded as metropolitan of ʿAmadiya in 1830 by the energetic Joseph Audo, who was transferred from Mosul to the diocese of ʿAmadiya under the settlement which confirmed Yohannan VIII Hormizd as patriarch and ended the schism in the Chaldean Church. During his metropolitanate Audo converted many of the villages of the Sapna valley to Catholicism. After he became patriarch in 1848 he was succeeded as metropolitan of ʿAmadiya in 1851 by ʿAbdishoʿ Thomas Dirsho, a monk of the monastery of Rabban Hormizd, who died in 1859.
He was succeeded as bishop of ʿAmadiya by Francis David of Araden (the only nineteenth-century Chaldean bishop from the ʿAmadiya region), who had been Sahhar's vicar-general for several years previously. He was consecrated for ʿAmadiya on 15 August 1910, resided in the Sapna village of Araden, and remained bishop of ʿAmadiya until his death in 1939.
Francis David's successors were Yohannan Qoryo (1942–6), Raphael Rabban (1947–57), Raphael Bidawid (1957–66), Andrew Sana (1966–7), Quriaqos Musa (1967–8), and Yohannan Qello (1973–2001).
In December 2001 the elderly bishop Yohannan Qello of ʿAmadiya, who died on 7 September 2002, was succeeded by Rabban Al-Qas. Rabban Al-Qas is also apostolic administrator of the Chaldean archdiocese of Erbil, vacant since the death of Yaʿqob Denha Scher in 2005.
