Jibrail Kassab (born 5 August 1938) was a bishop of the Chaldean Catholic Church who presided over the Eparchy of Saint Thomas the Apostle of Sydney in Australia. He was the bishop of this diocese since its inception on 21 October 2006[1] until his retirement in 2015.[2] His bishopric was based at St Thomas the Apostle Chaldean Catholic Church, Bossley Park, New South Wales.
Kassab was born in Tel Keppe, Iraq, to an Assyrian family. He was ordained a priest on 19 January 1961. Following 35 years of service in the priesthood, he was elevated to the episcopate by the then Patriarch of Babylon of the Chaldeans, Mar Raphael I Bidawid. Upon his installation, his first post was to serve as archbishop of the Archeparchy of Basra.
Following the difficult plight of Iraq's Chaldean Christians during the Iraq War, Pope Benedict XVI transferred Kassab to a safer area and created a diocese in Sydney that would cover all of Australia and New Zealand; he installed Kassab as its head prelate.
