The reading of the Augustana strengthened this friendly attitude of Charles. Both its content and its conciliatory tone, which was not at all in harmony with the picture of the Lutherans as sketched by Eck, caused him to be more kindly disposed toward Protestantism, and nourished his hope that religious peace might be attained by peaceable means. Other Catholic dignitaries and princes had been impressed in the same manner. July 6 Luther wrote to Hausmann: "Many bishops are inclined to peace and despise the sophists, Eck and Faber. One bishop [Stadion of Augsburg] is said to have declared in a private conversation, 'This [the Confession of the Lutherans] is the pure truth, we cannot deny it,' The Bishop of Mainz is being praised very much for his endeavors in the interest of peace. Likewise Duke Henry of Brunswick who extended a friendly invitation to Philip to dine with him, and admitted that he was not able to disprove the articles treating of both kinds, the marriage of priests, and the distinction of meats. Our men boast that, of the entire Diet, no one is milder than the Emperor himself. Such is the beginning. The Emperor treats our Elector not only graciously, but most respectfully. So Philip writes. It is remarkable how all are aglow with love and good will toward the Emperor. It may happen, if God so wills, that, as the first Emperor [Charles at Worms] was very hostile, so this last Emperor [Charles at Augsburg] will be very friendly. Only let us pray; for the power of prayer is clearly perceived." (St. L. 16, 882.) The Emperor's optimism was, no doubt, due to the fact that, unlike his theologians, he did not perceive and realize the impassable gulf fixed between Lutheranism and the Papacy, as appeared also from the Augustana, in which, however, the Emperor mistook moderation of tone for surrender of substance. 41.
