There was great uncertainty at the electoral court. In fact, a serious obstacle stood in the way of any union between the evangelical princes, and this obstacle was Luther and Melancthon. Luther desired that the evangelical doctrine should be defended by God alone. He thought that the less men interfered with it, the more striking would be God's interposition. It seemed to him that whatever measures they desired to take, they must be ascribed to an unworthy timidity or a blamable mistrust. Melancthon feared that the alliance of the evangelical princes would precipitate that very struggle which they were desirous of avoiding. The landgrave was not to be checked by these considerations, and he endeavoured to bring the neighbouring states into the alliance; but his exertions were not crowned with success. Frankfort refused to enter it. The Elector of Treves abandoned his opposition and accepted a pension from the emperor. Even the elector-palatine, whose evangelical disposition was well known, rejected Philip's proposals. Thus the landgrave failed on the side of the Rhine; but the elector, notwithstanding the opinions of the theologians of the Reformation, entered into negotiations with the princes who had at all times rallied round the powerful house of Saxony. On the 12th of June, the elector and his son, the Dukes Philip, Ernest, Otho, and Francis of Brunswick and Luneburg, Duke Henry of Mecklenburg, Prince Wolff of Anhalt, Counts Albert and Gebhard of Mansfeldt, assembled at Magdeburg; and there, under the presidence of the elector, they formed an alliance similar to that of Torgau. "Almighty God," said these princes, "having in his unspeakable mercy revived among men his holy and eternal Word, the food of our souls, and our greatest treasure here below; and great exertions having been made on the part of the clergy and their adherents to suppress and extirpate it, we, being firmly assured that He who hath sent it to glorify His name upon earth, will also know how to maintain it, bind ourselves to preserve that blessed Word for our people, and to that end to employ our goods, our lives, our states, our subjects, and all that we possess; putting our trust, not in our armies, but solely in the omnipotence of the Lord, whose instruments we desire to be."[459] Such was the language of the princes.

[Sidenote: ALLIANCE OF MAGDEBURG.] Two days after, the city of Magdeburg was received into the alliance, and the new duke of Prussia, Albert of Brandenburg, acceded to it by a separate treaty.
