The union of the Anglo-Saxon to the Danish crown could not fail to affect missionary operations in the North. It would seem at first sight as if the work would be strengthened and hastened, for now the Christianising energies of Britain would be added to those of Germany. As a matter of fact the situation became more complex and difficult: the union brought out the question whether the primacy of the new church should belong to Hamburg-Bremen or to Canterbury. It seems that Canute at one time held out hopes to Archbishop Ethelnoth of rising to metropolitan authority of the Danish as well as of the English nation. Such an arrangement would seem natural and highly desirable: the empire that Canute ruled from Winchester could be more readily held together if its ecclesiastical concerns were all directed from the cathedral at Canterbury.

These new plans with respect to the young Danish Church apparently date from the years immediately following Canute's return to England as Danish king (1020). His new interest in English ecclesiastical matters has been discussed elsewhere. In 1022, Ethelnoth consecrated three bishops for Danish sees: Gerbrand for Zealand (Roeskild); Reginbert for Funen (Odense); and Bernhard for the Scanian lands.[273] The sources also state that many other English bishops were sent to Denmark from England, but no names are given. It is to be noted that the names given above are not Anglo-Saxon but German. It has therefore been thought that these bishops were from Flanders or Lorraine, in which regions there was an ecclesiastical movement of some importance in the days of Canute.[274]

Of these three the most important was doubtless Gerbrand, whose cathedral was located at Roeskild, the royal residential city. At this time Unwan was archbishop of Hamburg-Bremen. Unwan was an aggressive and ambitious prelate; it was not with pleasure that he learned of the new bishops from the West; without the North as its mission-field, Bremen would be a sorry province. Bishop Gerbrand on his journey to his new parish,—he was probably sailing along the German coast according to custom,—was captured and brought before Archbishop Unwan who forced him to do proper homage. Apparently the German Prelate made a favourable impression on Bishop Gerbrand for through his influence the Archbishop induced Canute to agree that future bishops should be consecrated at Bremen.[275]

Tradition is doubtless correct in ascribing to Canute considerable activity in the endowment of churches. The statement that he established monasteries in Denmark is probably an error; if he attempted to do so, his efforts failed[276]; some time still had to pass before the viking could find contentment in the cloister. Danish monasticism dates from the closing years of the century, when twelve monks from Evesham on the Avon came on request of King Eric to found a monastery at Odense. It seems likely that the payment of Peter's pence dates from this reign. As to the amount of this tax nothing is known; but it is probable that the sum was a very modest one, as the Danes in England seem to have been specially favoured in this matter, the tax in the Danelaw being half as large as in the rest of England.[277]

Across the Sound in Scania, the introduction of Christianity was a slower process. We learn that in Sweyn's time an Englishman, Godebald, was appointed bishop there, and that he occasionally preached in the neighbouring sections of Sweden and Norway.[278] The results were evidently meagre, but it is significant that the preacher came from England.

The Norwegian Church is in a peculiar sense a daughter of the English Church. The first serious attempt at mission work in Norway was made about the middle of the tenth century, when King Hakon built a few churches and sent for English priests to officiate in them. One of these apparently bore the episcopal title, Sigfrid, a monk of Glastonbury.[279] The yeomanry gathered and slew the missionaries and the work came to nought.

When Olaf Trygvesson seized the kingship (995), he came accompanied by English priests. Among these was Bishop Sigurd, who was probably a Northumbrian of Norse ancestry, and evidently a man of strength and discretion. After the battle of Swald he seems to have continued his labours in Sweden. English missionaries also came with Olaf the Stout.

He was accompanied by a number of priests and bishops from England through whose doctrine and instruction he prepared his heart for God, and to whose guidance he entrusted the people who were subject to him. Among these were men who were famous for learning and virtue, namely Sigfrid, Grimkell, Rudolf, and Bernhard.[280]
