In this account by Dionysus Exiguus, Pachomius, a 20-year-old recruit during Constantine's reign, witnesses the compassion of Christians while detained for military service. Moved by their faith and kindness, he prays for divine guidance and vows to serve God. After being discharged, he becomes a catechumen and experiences a profound spiritual awakening. Seeking to become a monk, he approaches the ascetic Palaemon, who tests his resolve by describing the rigorous lifestyle required. Despite initial fear, Pachomius remains determined to endure the challenges ahead, bolstered by his faith in Christ.
