northern peoples were to be held in tutelage to the form and constitution of that which they had received: they continued to revere the patristic sources of Christian doctrines, and to look with awe upon the profane culture accompanying them.
Thus, as under authority, Christianity came to the Teutonic peoples, even to those who, like the Goths, were converted to the Arian creed. Likewise the orthodox belief was brought to the Celtic Britons and Irish as a superior religion associated with superior culture. But the qualities or circumstances of these western Celts reacted more freely upon their form of faith, because Ireland and Britain were the fringe of the world, and Christianity was hardly fixed in dogma and ritual when the conversion at least of Britain began.
Certain phrases of Tertullian indicate that Christianity had made some progress among the Britons by the beginning of the third century. For the next hundred years nothing is known of the British Church, save that it did not suffer from the persecution under Diocletian in 304, and ten years afterwards was represented by three bishops at the Council of Arles. It was orthodox, accepting the creed of Nicaea (A.D. 325) and the date of Easter there fixed. The fourth century seems to have been the period of its prosperity. It was affiliated with the Church of Gaul; nor did these relations cease at once when the Roman legions were withdrawn from Britain in 410. But not many decades later the Saxon invasion began to cut off Britain from the Christian world. After a while certain divergences appear in rite and custom, though not in doctrine. They seem not to have been serious when Gildas wrote in 550.

Also the mode of baptism and the tonsure differed from the Roman.
At the close of the sixth century the British Church existed chiefly in Wales, whither the Britons had retreated before the Saxons. Formerly there had been no unwilling-
