[Sidenote: Gregory's scheme of organization, 601.]
Gregory organized the new Church, in the full belief that it would extend over the whole island. He sent Augustin the "pall," a vestment denoting metropolitan authority, and constituting the recipient vicar of the Pope. Two metropolitan sees were to be established--the one at London, the residence of the East Saxon King Sæberct, who reigned as sub-king under Æthelberht, a crowded mart, and the centre of a system of roads; the other at York, the capital of the old Roman province north of the Humber. Both archbishops were to receive the pall, and to be of equal authority. At the same time, the unity of the Church was ensured, for they were to consult together and act in unison. Both the provinces were to be divided into twelve suffragan bishoprics, and as the northern province took in the country now called Scotland, they were of fairly equal size. This arrangement was not to be carried out until after Augustin's death. As long as he lived all the bishops alike were to obey him, and he was, we may suppose, to continue to reside at Canterbury. Moreover, the clergy of the Welsh or Britons were to be subject to him and to the future archbishops of the English Church. Augustin endeavoured to persuade the Welsh clergy to join him in preaching the Gospel to the Teutonic invaders, and held a meeting with them at or near Aust, on the Severn. But they refused to acknowledge his authority, or even to hold communion with him, and would not give up their peculiar usages with respect to the date of Easter and the administration of Baptism. At Augustin's request, Gregory sent him a letter of instructions as to the government of the Church. It bears witness to the Pope's largeness of mind. While morality and decency were to be enforced, the archbishop was not bound strictly to follow the Roman ritual; if he found anything that he thought would be helpful to his converts in the Gallican or any other use, he might adopt it, and so make up a use collected from various sources.
Excellent as Gregory's scheme would have been had Britain still been under Roman rule, it was unsuited to a country divided as England then was into several rival kingdoms. London did not become a metropolitan see, probably because Æthelberht was unwilling that the seat of ecclesiastical authority should be transferred from his own kingdom to the chief city of a dependent people, while Augustin had no wish that the church which he had founded at Canterbury, and the second monastery, now called after him, which he had begun to build there for a burying-place for himself and his successors, should be reduced to a lower rank. Other Roman clergy had been sent by Gregory to reinforce the mission, and of these Augustin consecrated Mellitus to be bishop of London, Justus to be bishop over Kent west of the Medway, with Rochester as the city of his see, an arrangement that marks an early tribal distinction, and Laurentius to be his own successor at Canterbury. Thus the metropolitan see remained with Kent. More generally, Gregory's scheme failed because it was founded on the old division of Britain as a province of the Roman empire, and was not adapted to the tribal distinctions of the English. Moreover, political circumstances determined the development of the Church; for the Roman mission received a series of checks, and the work of evangelization was taken up by Scottish missionaries. The kingdoms into which the country was divided were finally converted by efforts more or less independent of the Kentish mission; the work of evangelization followed tribal lines, and for sixty years after Augustin's death the tendency of the Church was towards disunion.
