Meanwhile, the British Isles were the theatre of another and independent religious movement. While the Saxons were subverting Christianity in Britain, St. Patrick was successfully engaged in laying the foundations of the Irish church.[371] We have seen (p. 76) that celibacy was not one of the rules enforced in the infant Irish church; but this was of comparatively little moment, for that church was almost exclusively monastic in its character, and preserved the strictest views as to the observance of the vows by those who had once taken them.[372] That the principles thus established were long preserved is evident from a curious collection of Hibernian canons, made in the eighth century, of which selections have been published by d’Achery and Martène. Some of these are credited by the compilers to Gildas, and thus show the discipline of the early British as well as of the Irish church.[373] Their tendency is towards the purest asceticism. A penance of forty days was even enjoined on the ecclesiastic who, without thought of evil, indulged in the pleasure of converse with a woman.[374] So in Ireland, a council held in 672 decrees that a priest guilty of unchastity, although removable according to the strict rule of discipline, may be allowed, if truly contrite, to retain his position on undergoing ten years of penitence[375]—an alternative, one might think, rather of severity than of mercy. One canon attributed to Gildas shows that in the British monastic system unchastity was considered the most heinous of offences, and also that it was sufficiently common;[376] while another alludes to the same vice among prelates as justifying immediate excommunication.[377] The missionary career by which the Irish church repaid the debt that it owed to Christianity is well known, and the form of faith which it spread was almost exclusively monastic. Luanus, one of the monks of Benchor, is said to have founded no less than a hundred monasteries;[378] and when Columba established the Christian religion in Scotland, he carried with him this tendency to asceticism and inculcated it among his Pictish neophytes. His Rule enjoins the most absolute purity of mind as well as body;[379] and that his teachings were long obeyed is evident when we find that, a hundred and fifty years later, his disciples are praised for the chastity and zeal of their self-denying lives by the Venerable Bede, who was fully alive to the importance of the rule, and who would have wasted no such admiration on them had they lived in open disregard of it.[380] Equally convincing is the fact that Scotland and the Islands were claimed to be under the supremacy of the see of York, and that during the long controversy requisite to break down their schismatic notions respecting the date of Easter and the shape of the tonsure, not a word was said that can lead to the supposition that they held any unorthodox views on the far more important subject of sacerdotal purity.[381]
