Mitropolitul '''Kallistos (Ware) de Diokleia''' (n. 1934, cunoscut, ca autor, şi după numele laic '''Timothy Ware''') este [[episcop]]ul titular al Patriarhiei de Constantinopol în Marea Britanie. Între anii 1966-2001, a fost profesor (Spalding Lecturer) de Studii de Ortodoxie Răsăriteană (Eastern Orthodox Studies) la Oxford University (Anglia). Este autorul a numeroase cărţi şi articole despre credinţa şi spiritualitatea ortodoxă. De asemenea, este invitat a da conferinţe în întreaga lume.
Born '''Timothy Ware''' in Bath, Somerset, England, Metropolitan Kallistos was educated at Westminster School ( to which he had won a scholarship) and Magdalen College, Oxford, where he took a Double First in Classics as well as reading Theology. In 1958, at the age of 24, he embraced the Orthodox Christian faith ( having been raised Anglican), traveling subsequently throughout Greece, spending a great deal of time at the [[ Monastery of St. John the Theologian (Patmos, Greece)| Monastery of St. John the Theologian]] in Patmos. He also frequented other major centers of Orthodoxy such as Jerusalem and [[ Mount Athos]]. In 1966, he was [[ ordination| ordained]] to the [[ priest| priesthood]] and was [[ tonsure| tonsured]] as a [[ monk]], receiving the name Kallistos.
In the same year, he became a lecturer at Oxford, teaching Eastern Orthodox Studies, a position which he held for 35 years until his retirement. In 1979, he was appointed to a Fellowship at Pembroke College, Oxford, and in 1982, he was [[ consecration of a bishop| consecrated]] to the [[ bishop|episcopacy]] as a [[titular bishop]] with the title '' Bishop of Diokleia'', appointed to serve as the assistant to the bishop of the [[ Church of Constantinople| Ecumenical Patriarchate]] 's [[ Greek Orthodox Archdiocese of Thyateira and Great Britain| Orthodox Archdiocese of Thyateira and Great Britain]]. Despite his elevation, Kallistos remained in Oxford and carried on his duties both as the parish priest of the Oxford Greek Orthodox community and as a lecturer at the University.
Since his retirement in 2001, Kallistos has continued to publish and to give lectures on Orthodox Christianity, traveling widely. Until recently, he was the chairman of the board of directors of the [[ Institute for Orthodox Christian Studies]] in Cambridge. He is the chairman of the group [[ Friends of Orthodoxy on Iona]]. He serves on the advisory board of the Orthodox Peace Fellowship.
On [[ March 30]] , 2007, the Holy Synod of the Ecumenical Patriarchate elevated the Diocese of Diokleia to Metropolis and Bishop Kallistos to Titular Metropolitan of Diokleia.
Metr. Kallistos is perhaps best known as the author of the book '' The Orthodox Church'', published when he was a layman in 1963 and subsequently revised several times. More recently, he produced a companion volume, '' The Orthodox Way''. But his most substantial publications have emerged from his translation work. Together with [[G. E. Palmer]] and [[Philip Sherrard]]), he has undertaken to translate the [[ Philokalia]] ( four volumes of five published to date); and with Mother Mary he produced English translations of the [[ Lenten Triodion]] and [[ Festal Menaion]].
