Confrontation with Valens
The defining episode of Vetranion's episcopate, reported by the church historian Sozomen, came during the emperor Valens' campaign against the Goths in the Scythian region. Halting at Tomis, Valens pressed the citizens to embrace Arianism and to reject the Nicene Creed. According to the Orthodox account, the bishop boldly denounced the emperor, applying to himself the words of the psalm, 'I spoke of thy testimonies before kings, and was not ashamed.' Valens exiled him in response, but the outcry of the people of Tomis over their bishop's banishment compelled the emperor to restore him to his see. For this firm resistance he is honored as a confessor — one who suffered for the faith without being put to death.
