Hand-Painted Icon of Saint Theodore Tyron and Saint Theodore Stratelates

"Saint Theodore of Amasea (Greek: Θεόδωρος) is one of the two saints called Theodore, who are venerated as Warrior Saints and Great Martyrs in the Eastern Orthodox Church. He is also known as Theodore Tyron (or Tyro or Tiron or Tiro or Teron). The other saint of the same name is Theodore Stratelates, also known as Theodore of Heraclea, but this second St Theodore may never have had a separate existence. When the epithet is omitted, the reference is usually to St Theodore of Amasea. "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). In the Eastern church, St Theodore of Amasea is celebrated on 8 February or on 17 February or on the 1st Saturday in Lent.

Theodore Stratelates (Ancient Greek: Στρατηλάτης, lit. ''the General' or 'Military Commander''; Coptic: ⲡⲓⲁⲅⲓⲟⲥ Ⲑⲥⲟⲇⲱⲣⲟⲥ), also known as (Theodore of Heraclea) is a martyr and Warrior Saint venerated with the title Great-martyr in the Eastern Orthodox Church, Eastern Catholic and Roman Catholic Churches and Oriental Orthodox Churches.

Theodore the Martyr was the name of a number of Christian saints. Two of the best known, Theodore of Amasea and Theodore Stratelates, were probably the same person. A variety of stories are told about Theodore the Martyr. Relics of Theodore the Martyr, including at least four bodies as well as body parts, were taken to Venice, where he is one of the patron saints, or to other places in Western Europe.

Theodore of Amasea was almost certainly the same person as Theodore Stratelates. Theodore Stratelates, also called Theodore of Heraclea, was a Roman general in the army of the Emperor Licinius (r. 308–324). He was either beheaded or crucified at the command of the emperor. Theodore Stratelates is an important saint in the Greek Orthodox Church."
