"Born in Asia and educated in Constantinople, he went into the army after completing his studies and became an officer. Reading the Holy Scriptures, he came upon the Saviour's words: 'If thou wilt be perfect, go and sell all thou hast, and give to the poor, and thou shalt have treasure in heaven; and come and follow Me' (Matt. 19:21). These words made such an impression on him that he sold and gave away all that he had, and went off to the desert. After long asceticism and striving for purification, he founded the community of the 'Wakeful Ones' (Acoemetae) with a special rule. According to this rule, the services in the church continued day and night in unbroken sequence. The brethren were divided into six groups, each having its appointed hours of day or night to go to church and take over the reading and singing from the previous group. He travelled a great deal over the East, bringing people to faith in Christ, disputing with heretics, working miracles by God's grace and growing old in the service of the Lord Jesus. He finished his earthly course in Constantinople in the year 430, where his relics revealed the miraculous power and glory with which God had glorified His holy servant." (Prologue)
