Great Martyr Theodore the Tyro
Theodoros From the Greek name Θεοδωρος (Theodoros), which meant "gift of god" from Greek θεος (theos) "God" and δωρον (doron)"gift".
Tiro is a word from classical Latin meaning a "recently enlisted soldier or recruit". The Latin word was transliterated into Greek with various spellings (Τύρων, Τίρων, Τήρων or Τείρων).
Saint Theodore who was from Amasia of Pontus, contested during the reign of Maximian (286-305). He was called Tyro, from the Latin Tiro, because he was a newly enlisted recruit. When it was reported that he was a Christian, he boldly confessed Christ; the ruler, hoping that he would repent, gave him time to consider the matter more completely and then give answer. Theodore gave answer by setting fire to the temple of Cybele, the "mother of the gods," and for this he suffered a martyr's death by fire. See also the First Saturday of the Fast.
