Saint '''Dorotheus''' Bishop of Tyre (ca. 255 – 362 ) is traditionally credited with an Acts of the Seventy Apostles (which may be the same work as the lost Gospel of the Seventy ), who were sent out according to the Gospel of Luke 10:1.
Dorotheus, a learned priest of Antioch
, the teacher of the Church historian [[Eusebius of Caesarea]], was appointed director without having to renounce his religion (Eusebius,VII.32) . Dorotheus is said to have been driven into exile during the persecution of Diocletian, but later returned. He attended the Council of Nicaea in 325, but was exiled to Odyssopolis (Varna) on the Black Sea in Thrace by Julian the Apostate. There the 107 year old priest was martyred for his faith. His feast day is observed [[June 5]]. <ref> "Saint Dorotheus of Tyre". Saints. SQPN. Retrieved April 5, 2011.</ref>
