We have elsewhere treated of the reformation of Bremen, of Augsburg, and of Würtemberg. Pomerania was not yet reformed, although Pomeranus, the reformer to whom it had given birth, took so prominent a part in the work in many towns and countries. The duke, Bogislas, and the bishop of Camin were resolutely opposed to the Reformation; but here and there amongst the townsmen were ardent aspirations towards the Gospel; and occasionally, likewise, there were excesses and destruction of images. The clergy and the nobles were on the side of the pope; the towns were for the Bible; and the two camps were almost at war. The duke on his travels, in 1523, passed through Wittenberg, and the bishop of Camin, as curious as the duke, appears to have accompanied him. The reformer in his sermon spoke, amongst other things, of the carelessness and luxury of bishops. The duke smiled and looked at his companion.[497] Bogislas sent for Luther, conversed with him in a friendly manner, and said: 'I should like for once to confess to you.' 'I am quite willing,' said the reformer; 'my only fear is that as your Highness is a great prince, you are also a great sinner.' The duke made frank reply that this was only too true. The duke felt also the influence of his son, the young prince Barnim, who had studied at Wittenberg from 1518 to 1521, and who had attended the disputation at Leipsic in 1519. His brother George, on the other hand, brought up at the court of Duke George of Saxony, had there imbibed a hatred of the Gospel. After the death of Bogislas, these two princes became leaders of the two opposing parties. Barnim sent word to the allies of Smalcalde--'What my brother builds up, I shall cast down.' The mother of George appeared friendly to his purpose; and her son Philip having come to an understanding with Barnim, a diet was convoked, in 1533, at Treptow. The towns laid before it a scheme of reformation, which was well received; and Pomeranus was summoned to settle the new order of things. The nobility, however, and the clergy, particularly the bishop of Camin, still energetically opposed the evangelical work. [Sidenote: WESTPHALIA.]
