A vivid hagiographical account tracing the monk’s journey from ascetic beginnings to his role as a towering theologian and defender of orthodox Christology; the narrative follows his theological struggles—most notably his opposition to Monothelitism—his pastoral labors, literary output, and the persecution he endured, including exile and brutal mutilation, which he bore as a confessor of the faith. Interwoven with accounts of miracles, ascetic practices, and doctrinal argument, the portrait aims to honor his sanctity and enduring influence on Byzantine theology and the Church’s understanding of Christ’s will and nature.
