The blessed one reflected on the zeal and faith he observed in the brothers and the magnitude of their devotion. What could this mean? Through the Holy Spirit, it dawned on him that even in these quarters he was being called to wage the struggle. Energized by this conclusion, he made himself ready, and prayed for Christ's will to be done swiftly. And God, Who loves humanity, was swift to answer his prayer.
Alexander took up residence near the shrine of the sainted martyr Menas, and within a few days there flocked to him noble athletes of Christ out of every monastery in the area—three hundred of them, all sound of mind, belonging to three races: Romans, Greeks, and Syrians. To fulfill his mission of hymn-singing without pause, Alexander separated them into six groups, and schooled them in monastic poverty, molding everything after the pattern of his old rule. Within a matter of days, the hierarchy he laid out was ordered as to every virtue, and the basis for their struggle was made plain to all. For he grouped them in tens and fifties, ordaining decarchs and penetecontarchs to lead them, and hourly they poured their strength into singing the praises of God.
On beholding their systemized struggle, their ceaseless hymn-singing, their immaculate poverty, and the incredible mysteries made no less wondrous by the evident truth of their accomplishment, the commonfolk of the city came devoutly to Alexander as a benefactor and teacher, and inhaled his teachings about hope and the life to come. Before long, he had become the harbor of salvation and educator of justice for all. When he was silent, his life gave continual voice, crying its admonishments aloud against the adulterators of God's commandments, while his free and unrestrained speech excoriated the unrepentant. Above all, though, it was seeing the extremities of poverty the brothers took on, and the severity of their discipline, and the fact that their possessions were limited to parchments containing the holy scriptures, and their capacity for singing hymns without pause, and the bodiless way they inhabited their bodies—it was seeing all these things that roused the people's astonishment and praise of God, Who had revealed His incredible mysteries even in those quarters.
