Acathius was a third-century bishop who served in Melitene, a city in the Roman province of Second Armenia, though some traditions identify him as a bishop of Antioch. Living during the persecutions under Decius, he was brought before the tribunal of Marcian to defend his religious convictions. While he faced a death sentence, his steadfastness and wisdom reportedly moved the Emperor to release him from custody following a period of intense suffering. He was also known by the name Agathangelos, which translates to "good angel."
Life and work
Acathius was recognized for his impressive doctrinal teachings and the miracles he performed. During his time in Melitene, he maintained his faith despite the legal challenges posed by the Roman authorities. He should not be confused with a later bishop of the same name who participated in the Council of Ephesus in 431.
Veneration
The saint is honored within the Catholic, Eastern Orthodox, and Anglican traditions. In the Eastern Orthodox Church, he is commemorated on several occasions, most notably on 31 March. His legacy as a teacher and miracle worker continues to be recognized across these various Christian denominations.
