Not long after, however, there arose up a certain whited wall, pretending that he was for upholding the traditions of his elders, which caused disunion and partly rendered void what had been agreed to. Upon this it was determined by ‘our seniors’ that if questions of a more weighty character should arise, they ought to be referred, according to the decree of the synod, to the head of cities. They therefore sent some that they knew to be wise and humble, as children to a mother, and having a prosperous journey by the will of God, and some of them having come to the city of Rome, they returned in the third year, and they saw everything accord with what they had heard, or rather they obtained a much clearer view of the matter, as seeing instead of hearing; and, being in one lodging with a Greek and a Hebrew, a Scythian and an Egyptian, they all celebrated their Easter together in St. Peter’s Church, while they differed from them by a whole month. And they solemnly assured him of this, saying, This Easter is celebrated to our knowledge all the world over. ‘These statements,’ adds Cummian, ‘I have made, not with a view to attack you, but to defend myself.’ Such is the substance of Cummian’s letter;[314] and as the times for celebrating Easter according to the Roman and to the Irish computation would be separated by the interval of a month in the year 631,[315] the synod must have been held about 630, the return of the deputies taken place in 633, and the letter have been written in the following year. According to Bede, Pope Honorius in this year ‘wrote to the nation of the Scots, whom he had found to err in the observance of Easter, earnestly exhorting them not to esteem their small number, placed in the utmost borders of the earth, wiser than all the ancient and modern churches of Christ throughout the world, and not to celebrate a different Easter, contrary to the Paschal calculation and the synodical decrees of all the bishops upon earth;’[316] and the result was that, as Bede tells us, ‘the Scots which dwelt in the southern districts of Ireland, by the admonition of the bishop of the Apostolic See, learned to observe Easter according to the canonical custom;’ while the northern province of the Scots and the whole nation of the Picts adhered to the old custom of the country.[317]
