When we come to consider the flight of the Christian Britons before the Saxon invaders, it is worth while to consider how far Christianity really had occupied the land generally, even at the date of its highest development. The Britons were rather sturdy in their paganism. Their Galatian kinsfolk were pagans still in the fourth century, to a large extent. Their kinsfolk in Gaul were pagans to a large extent as late as 350. It seems to me not improbable that a good many of the Britons stayed behind when the Christian Britons fled before the heathen Saxons; and that the flocks whom British bishops led to places of safety, in Britany and the mountains of Britain, may have been not very numerous. If on the whole the fugitives were chiefly from the municipal centres, places so completely destroyed as their ruins prove them to have been, the few Christians left in the country places would easily relapse. But they would retain the Christian tradition; and from them or their children would come such information as that which enabled Wilfrid to identify, and recover for Christ, the sacred places of British Christianity. We should, I think, make a serious mistake if we supposed that the British Church in Cornwall and Devon was originally formed by fugitives from other parts of the island. The monuments seem to shew that Christianity was established there as well as in other parts of Britain in Romano-British times. Such monuments as we find there and in Wales do not exist in other parts of the island where the British Church existed; and it is an interesting and important question, is that because these parts were unlike the other parts, or is it because in other parts the processes of agriculture and building have broken up the old stones with their rude inscriptions? We now and then come across a warning that the total absence of monumental remains in a place may not mean that there never were any. Many of you would say with confidence that we certainly have not monumental remains from the original cathedral church of St. Paul's, built in the first years of Christianity and burned after the Conquest. But we have. They found some years ago a Danish headstone, with a runic inscription of the date of Canute, twenty feet below the present surface of the churchyard. You can see it in the Guildhall Library, or a cast of it in our library here. I have no doubt there are many such, if we could dig.
