Biography
Mar Eshai was born on the 26th of February, 1908 in Qudchanis, the mountainous region located in southern Turkey. Mar Eshai was raised with great care while received the necessary theological and liturgical training by the late Archdeacon of the Patriarch, the Very Reverend Thoma of Ashita and by the Metropolitan of Rustaqa, His Grace, Mar Yosip Khnanishoo, who was also his uncle. At the age of twelve, due to geopolitical upheavals at the time, Mar Eshai was ordained as Patriarch in 1920, succeeding his uncle, Mar Poulus Shimun, XXII. He was educated in England, studying theology at Canterbury and at Westcott House, University of Cambridge. As early as 1926 at the age of 18, the Patriarch attended the Nicene Council Commemoration held at Westminster Abbey, London. The Church and State Conference held in Oxford and the Faith and Order Conference held in Edinburgh were both attended by Mar Eshai in 1937. The distinguished Athenaeum Club of London had bestowed upon Eshai by conferring an honorary membership. He was also a member of the American Historical Society and other organizations as well as being a representative to the World Council of Churches and being a notable among the chronicles of Who’s Who. Numerous appeals and publications concerning the Assyrian Question, written by the Patriarch and presented to the British Government and various international bodies, highlight him as a writer of distinction. He was the translator or author of several books on the theology and history of the Church of the East The volatile political environment and uncertainties for the church caused in 1933 by the independence of Iraq from colonial rule forced the patriarch to be exiled to Cyprus away from the new see in Bebadi. In 1940, he relocated again, to Chicago, Illinois in the United States. Prior to Mar Eshai Shimun’s intervention, Assyrians living among their Islamic neighbor’s shared a tenuousness relationship that was firmly rooted in mistrust by both sides. Therefore, in 1948 Eshai made a revolutionary announcement of a new policy for the Assyrian people and the Church of the East. Through direct contact to embassy representatives of the Middle Eastern countries in Washington and at the United Nations Headquarters, he broke down the walls of suspicion and misunderstanding. This new policy decreed Assyrians and members of the Church of the East all over the world to remain as loyal and faithful citizens of the countries in which they lived, something that had never been done before. Mar Eshai became an American citizen about 1949 and settled in the San Francisco area in 1954. In 1964, a dispute over hereditary succession and church calendars caused the metropolitan of the Church of the East in India to break away and Mar Thoma was stopped from his duties in the Church of the East. In 1995 Mar Eshai's successor, Mar Dinkha IV, was able to mostly heal the rift. 17% remain separated from the main body of the Church of the East. Mar Eshai sought to resign as patriarch for health reasons in the late 1960s, but he was persuaded to remain in office. Some activists within the church wanted the patriarch to take a more active role in pushing for a homeland for the Assyrian people, as he had before 1933. On a separate track, rumors began circulating with those who consistently went against him decided it was time to have someone new. On 6 November 1975, the patriarch was shot and killed at the door of his home in San Jose, California, by David Malek Ismail, which was a shock to the Assyrian nation, after all it was the Malek Ismail family that had protected the Shimun patriarchal line for generations. According to trial records, Ismail said he was upset over the patriarch's marriage; however, the records suggest links between Ismail and church dissidents. According to Deputy District Attorney Brian Madden, the murder of the patriarch Mar Shimun was the outcome of a plot among church dissidents. When the church council met in London on 17 October 1976, it elected as patriarch Mar Dinkha IV.
