As historian A. J. Wylie explains in his "History of the Scottish Nation", Vol. III., “The 12th century, particularly in Scotland and Brittany, was a time when two Christian faiths of different origins were contending for possession of the land, the Roman Church and the old Celtic Rite. The age was a sort of borderland between Culdeeism and Romanism. The two met and mingled often in the same monastery, and the religious belief of the nation was a mumble of superstitious doctrines and a few scriptural truths.”
