In the fourth century, when the monastic institute spread from the East into the West, the community life of the bishops and their clergy assumed, in many places, a yet more regular form. St. Eusebius of Vercelli, who had himself been committed by his mother in early youth to the care of Pope Eusebius, and had been instructed and baptized by him, was the first to erect an episcopal monastery in his own city, which became a nursery of illustrious prelates. This was in 354, and forty years later St. Augustine established a similar monastery at Hippo, which is regarded as the parent of all houses of canons regular. Yet, though these establishments are sometimes called _monasteries_, the rule of life observed in them is ordinarily designated the _Apostolic_ rule,[13] and the monasteries or colleges of a similar kind established in Gaul and Britain are said to be “of the Apostolic Order.” From this time the community life of the clergy became subject to fixed rules or canons. In 398 the fourth Council of Carthage, whilst prescribing the laws for the administration of holy orders, regulates the manner of life to be observed by the bishops with their clergy in very precise terms. The bishop is to have his residence near the church; he is to commit the care of temporalities to his archdeacon, and to occupy himself exclusively with prayer, study and preaching. In the church he is to have a higher seat than his clergy, but in the house he must recognise them as in all respects his colleagues, and never to suffer them to remain standing while he is seated.[14] Similar canons were passed in the first Council of Toledo, held two years later.
