From that time Frederick William I. was Zinzendorf's fast friend. He encouraged him to become a Bishop of the Brethren. The Count was still in doubt. For some months he was terribly puzzled by the question whether he could become a Moravian Bishop, and yet at the same time be loyal to the Lutheran Church; and, in order to come to a right conclusion, he actually came over to England and discussed the whole thorny subject of Moravian Episcopal Orders with John Potter, Archbishop of Canterbury. The Archbishop soon relieved his mind. He informed the Count, first, that in his judgment the Moravian Episcopal Orders were apostolic; and he informed him, secondly, that as the Brethren were true to the teaching of the Augsburg Confession in Germany and the Thirty-nine Articles in England, the Count could honestly become a Bishop without being guilty of founding a new sect. The Count returned to Germany. He was examined in the faith, by the King's command, by two Berlin Divines. He came through the ordeal with flying colours, and finally, on May 20th, he was ordained a Bishop of the Brethren's Church by Bishop Daniel Ernest Jablonsky, Court Preacher at Berlin, and Bishop David Nitschmann {1737.}. The situation was now remarkable. As soon as Zinzendorf became a Bishop, he occupied, in theory, a double position. He was a "Lutheran Bishop of the Brethren's Church." On the one hand, like Jablonsky himself, he was still a clergyman of the Lutheran Church; on the other, he was qualified to ordain ministers in the Church of the Brethren. And the Brethren, of course, laid stress on the latter point. They had now episcopal orders of their own; they realized their standing as an independent church; they objected to mere toleration as a sect; they demanded recognition as an orthodox church. "We design," they wrote to the Counts of Isenberg, "to establish a home for thirty or forty families from Herrnhut. We demand full liberty in all our meetings; we demand full liberty to practise our discipline and to have the sacraments, baptism and communion administered by our own ministers, ordained by our own Bohemo-Moravian Bishops." As the Counts agreed to these conditions the Brethren now laid out near the castle a settlement after the Herrnhut model, named it Herrnhaag, and made it a regular training-ground for the future ministers of the Church. At Herrnhut the Brethren were under a Lutheran Pastor; at Herrnhaag they were independent, and ordained their own men for the work. They erected a theological training college, with Spangenberg as head. They had a pædagogium for boys, with Polycarp Müller as Rector. They had also a flourishing school for girls. For ten years this new settlement at Herrnhaag was the busiest centre of evangelistic zeal in the world. At the theological college there were students from every university in Germany. At the schools there were over 600 children, and the Brethren had to issue a notice that they had no room for more.
