Episcopate and Witness
The tradition presents Dorotheus as a learned shepherd whose long life bridged the eras of persecution and imperial favor. Having survived the Diocletianic persecution by withdrawal rather than confrontation, he returned to a Church newly at peace and devoted decades to the instruction and expansion of his flock, the sources crediting him with the conversion of many pagans during his more than fifty years on the throne of Tyre.
Some accounts add further detail to his career: that he had earlier been a learned priest of Antioch and a teacher of the church historian Eusebius of Caesarea, that he attended the First Ecumenical Council at Nicaea in 325, and that he was a eunuch. His martyrdom came at the very end of a life of extreme length; too old to be a public threat, he was nonetheless sought out under Julian, and his refusal to sacrifice brought him the death he had earlier evaded. Because he was both a bishop and put to death for the faith, he is reckoned a hieromartyr.
