The Celtic monastic system was apparently in vogue among the remnant of the ancient British Church in Wales and the West Country on the coming of St. Augustine. Little is known with certainty, but as the British Church was Celtic in origin it may be presumed that the Celtic type of monachism prevailed amongst the Christians in this country after the Saxon conquest. Whether it followed the distinctive practice of Irish monasticism in regard to the position of the abbot and the subject bishops may perhaps be doubted, as this does not appear to have been the practice of the Celtic Church of Gaul, with which there was a close early connection. It has usually been supposed that the Rule of St. Columbanus represented the normal life of a Celtic monastery, but it has been lately shown that, so far as regards the Irish or Welsh houses, this Rule was never taken as a guide. It had its origin apparently in the fact that the Celtic monks on the Continent were induced, almost in spite of themselves, to adopt a mitigated rule of life by their close contact with Latin monasticism, which was then organising itself on the lines of the Rule of St. Benedict.[8] The Columban Rule was a code of great rigour, and “would, if carried out in its entirety, have made the Celtic monks almost, if not quite, the most austere of men.” Even if it was not actually in use, the Rule of St. Columbanus may safely be taken to indicate the tendencies of Celtic monasticism generally, and the impracticable nature of much of the legislation and the hard spirit which characterises it goes far to explain how it came to pass that whenever it was brought face to face with the wider, milder, and more flexible code of St. Benedict, invariably, sooner or later, it gave place to it. In some monasteries, for a time, the two Rules seem to have been combined, or at least to have existed side by side, as at Luxeuil and Bobbio, in Italy, in the seventh century; but when the abbot of the former monastery was called upon to defend the Celtic rule, at the Synod of Macon in A.D. 625, the Columban code may be said to have ceased to exist anywhere as a separate rule of life.
