Sabrisho I (also Sabr-Ishu, Syriac for "hope in Jesus") was Patriarch of the Church of the East from 596 to 604, during the rule of King Khosrow II.
Sabrisho was born in 525 in Beth Garmai (near modern-day Kirkuk) in the Sasanian Empire.
[1] Shortly after his appointment in 596, he started to convene a synod which was held in 598 in Seleucia-Ctesiphon[2] where he anathematized the opponents of Theodore of Mopsuestia.
[3] Other conflicts during Sabrisho's tenure included that with Henana of Adiabene, who he excommunicated from the Church.
There was a subsequent power struggle over the election of a new Patriarch, between the King, his wife Shirin, and the Synod (council) of bishops.
