He was also still a strong opponent of the Roman Catholics, for it was by his advice that the Elector of Saxony declared himself ready to send deputies to a council to be convened at Trent, but only under the condition that the Protestants should have a share in the discussions, and that the Pope should not be considered as the presiding officer and judge. As it was agreed upon to send a confession to Trent, Melanchthon drew up the "Confessio Saxonica" which is a repetition of the Augsburg Confession, discussing, however, in greater detail, but with moderation, the points of controversy with Rome. Melanchthon on his way to Trent at Dresden saw the military preparations of Maurice of Saxony, and after proceeding as far as Nuremberg, returned to Wittenberg in March 1552, for Maurice had turned against the emperor. Owing to his act, the condition of the Protestants became more favourable and were still more so at the Peace of Augsburg (1555), but Melanchthon's labours and sufferings increased from that time.
