Repentance and Monastic Calling
The accounts of Anthony's life present him as a figure shaped by a single grave sin and the lifelong repentance it set in motion. By tradition he was of an angry temperament in youth, and the killing of a man — described as a fight or brawl — left him unable to find rest. His monastic path at Supraśl and then at Karyes is framed throughout as a deliberate answer to that guilt, culminating in his pursuit of martyrdom as a final act of atonement. His desire for a martyr's death is said to have been renewed by news of another contemporary martyr, the New Martyr George.
