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 in Patmos. He also frequented other major centers of Orthodoxy such as Jerusalem and Mount Athos. In 1966, he was ordained to the priesthood and was tonsured as a monk, receiving the name Kallistos.
