Since 2014, he serves as Metropolitan of Baghdad, Kuwait and Dependencies, under the jurisdiction of Greek Orthodox Patriarchate of Antioch and All the East.
In October 2010, he appointed dean of the St. John of Damascus Institute of Theology and abbot of the Our Lady of Balamand Patriarchal Monastery in northern Lebanon.
[2] In September 2013, he was dismissed from the post of Dean,[3] while remaining the abbot of the Balamand monastery until his election to Baghdad see[4] On 7 October 2014, after the retirement of long serving (since 1969) Metropolitan Constantine Papastephanou, the Holy Synod of Antioch elected bishop Ghattas Hazim as new "Metropolitan of Baghdad, Kuwait and Dependencies".
[5] Since northern parts of his new diocese (specially Iraq) were severely affected by devastating wars and conflicts during past two decades, upon arriving in Baghdad he was faced with many problems, starting from the fact that over 90% of the Eastern Orthodox Christians in the country have been displaced due to the security chaos which has prevailed there for the past generation.
Because of that, his official seat remains in Baghdad, but administrative headquarters of the Archdiocese are still located in Kuwait.
