Metropolitan Pachomius of Behira

Following the death of the Patriarch of Alexandria, the eldest and most senior metropolitan in the Synod of the Church is customarily called to serve as Locum Tenens until the election of a new pope. When Pope Shenouda III died on 17 March 2012, Metropolitan Mikhail of Asyut, who was the most senior metropolitan at the time declined the role citing his poor health. Metropolitan Pachomius, being second in seniority, was then chosen to fill the position. He served as acting Patriarch until the enthronement of Pope Tawadros II, (formerly General Bishop Tawadros of Behira, who served alongside Metropolitan Pachomius) on 18 November 2012.

On 2 December 1990, he was elevated to the rank of metropolitan by Pope Shenouda III.

He accompanied Pope Shenouda III on many of his pastoral and diplomatic visits, including those to the Vatican (1973), Ethiopia (1974), the United States (1977), and Sudan (1978).

On 12 December 1971, he was recalled to Egypt and consecrated as Pachomius (named after St. Pachomius), Bishop of Behira and Pentapolis, by Pope Shenouda III. He was the first bishop to be consecrated by the then newly elected Pope Shenouda III.

In 1967, he was sent to serve in Sudan, and there he preached the Gospel and baptized many of the indigenous people who lived there. On 28 July 1968, he was elevated to the rank of Hegumen by Bishop Daniel of Khartoum. In 1971, he was sent by Pope Cyril VI to Ethiopia, and later to London, where he established the first Coptic Church in the United Kingdom.

In 1962, he returned to Egypt and joined the Syrian Monastery, being tonsured a monk under the name Antonius the Syrian (Arabic: أنطونيوس السرياني). He was ordained as a priest on 2 January 1966, and entrusted with preparing servants and missionaries for Africa.

After receiving his Bachelors of Commerce, in 1956, he moved to Damietta where he found employment first in the Ministry of Finance, and later as an accounting manager in the Ministry of Health. He also became the general secretary of Sunday school at this time. In 1959, he returned to Greater Cairo to live as a consecrated servant. He managed a house for deacons in Giza, and began attending the Coptic Theological and Clerical College, and then the Higher Institute of Coptic Studies. In 1961, he was sent on a pastoral mission to serve as a Deacon in Kuwait.

He was born as Samir Kheir Sokkar (Arabic: سمير خير سكر), on 17 December 1935 in Shebein el-Kom, Menoufia, Kingdom of Egypt. His family relocated to Tanta around 1945 then to Zaqaziq in 1949. In 1949, at the age of thirteen, he began to serve in Sunday School, at the behest of Walim Shenouda, one of the early deputy servants of the movement. He served in various cities and villages establishing classes and youth meetings. During this time he met with Nazir Gayed (Pope Shenouda III) and learned from him the essentials of service. In 1952, he moved to Greater Cairo to attend Ain Shams University; during this time he was one of the founding members of a college meeting, and served in the villages of Giza.
