The peremptory summons could be construed as an affront to the University of Wittenberg, on whose boards the _Ninety-five Theses_ had been posted. Luther wrote to his friend Spalatin (George Burkhardt of Spalt, 1484-1545), who was chaplain and private secretary to the Elector Frederick, suggesting that the prince ought to defend the rights of his University. Spalatin wrote at once to the Elector and also to the Emperor Maximilian, and the result was that the summons to Rome was cancelled, and it was arranged that the matter was to be left in the hands of the Papal Legate in Germany, Thomas de Vio, Cardinal Cajetan(166) (1470-1553), and Luther was ordered to present himself before that official at Augsburg. The interview (October 1518) was not very satisfactory. The cardinal demanded that Luther should recant his heresies without any argument. When pressed to say what the heresies were, he named the statement in the 58th Thesis that the merits of Christ work effectually without the intervention of the Pope, and that in the _Resolutiones_ which said that the sacraments are not efficacious apart from faith in the recipient. There was some discussion notwithstanding the Legate’s declaration; but in the end Luther was ordered to recant or depart. He wrote out an appeal from the Pope ill-informed to the Pope well-informed, also an appeal to a General Council, and returned to Wittenberg. When Luther had posted his _Theses_ on the doors of the Church of All Saints, he had been a solitary monk with nothing but his manhood to back him; but nine months had made a wonderful difference in the situation. He now knew that he was a representative man, with supporters to be numbered by the thousand. His colleagues at Wittenberg were with him; his students demonstratively loyal (they had been burning the Wimpina-Tetzel counter-theses); his theology was spreading among all the cloisters of his Order in Germany, and even in the Netherlands; and the rapid circulation of his _Theses_ had shown him that he had the ear of Germany. His first task, on his return to Wittenberg, was to prepare for the press an account of his interview with Cardinal Cajetan at Augsburg, and this was published under the title, _Acta Augustana_.
