Alcfrid at once left Iona, and was chosen king. He was a good and just prince, much under the influence of Wilfrid and inclined to adopt Roman fashions.
It becomes necessary now to speak of a controversy that rent the unity of the Church in England.
All Northumbria, Mercia and Essex had received the faith from Iona, the monastic capital of the Scots, whereas Kent and Wessex had received it from Rome.
Iona had been founded in 563 by S. Columba, an Irishman; and it was from Iona that S. Aidan, the Apostle of Northumbria, had been sent. Lindisfarne, the seat of the Bishops of Northumbria, was a daughter of Iona.
Now, there were certain differences between this Celtic Church and that of Rome and Gaul.
In the first place, the Britons and Irish had been cut off from communication with the rest of Europe by the troubles that afflicted the Empire as it fell into ruin under the blows of the Barbarians. Consequently they were unaware that a change had been agreed on in the observance of Easter. It was discovered in 387 that the system of calculating Easter was erroneous, and Pope Hilary employed one Victorinus to frame a new cycle, which was thenceforth followed in the Latin Church. But of this change the British and Irish Church knew nothing; and when Augustine and his followers arrived in Kent they found that the ancient Church of the Britons observed Easter on a different day from themselves.
That was not all. The Celtic monks had a different tonsure or mode of cutting of the hair from the Latin monks. Instead of shaving the top of the head, and leaving the hair as a crown, they shaved the front of the head from ear to ear. Now, the reason of the use of the tonsure among the Celts was this. The cutting of the hair signified adoption, and there is some reason to believe that every tribe or clan clipped its hair in its own peculiar fashion. The Ecclesiastical tribe adopted the shaving of the front of the head; and every one so shaven belonged in the ecclesiastical clan.
When S. David settled in the valley where is now the Cathedral that bears his name, there was an Irish Pict invader living in a camp hard by. He had seized on that bit of Pembrokeshire. His name was Boia, and he was a pagan. His wife was highly incensed at Christian monks settling on their land and near at hand, and she tried to goad her husband to murder them. But he was a good-natured man, and he absolutely refused to do her will. Then she resolved to get her heathen gods to strike them dead, and in order to gain the favour of the gods she must offer them a sacrifice of one of her children. But she had none of her own; so she called to her a little girl, a daughter of her husband by a former wife, and told her she would cut her hair. She took the girl down into a sunny place in a hazel grove on the slope of the hill, and there, with her shears, cut her hair. Now, as cutting the hair was esteemed to be adoption, by this act she had made the child her own; so she instantly with the shears cut the girl’s throat as an offering to the gods. Now the British clergy, by their form of cutting the hair, regarded themselves as adopted into the family of God, or the Ecclesiastical tribe.
Augustine and the Latin clergy could not understand this. Instead of arguing with the native Christians they denounced them. They called them Judaisers because they observed Easter at the wrong time, which was false; and they called the tonsure of the Celts that of Simon Magus, which was nonsense.
There were other peculiarities. The British Church used unleavened bread at the Eucharist, and the Latin Church at that time only such bread as was leavened. Also, another high misdemeanour was that, instead of employing a single collect before the Epistle and Gospel, there were more than one said. In these two last particulars the Latin Church has altered now her practice; in the matter of the unleavened bread, the change took place in the tenth century.
