His opening sermon, on New Year's Day, 1519, stirred his hearers in a marvellous way, and at once stamped him as an evangelical reformer of no common type. He briefly sketched out the plan by which he proposed to be guided in his future sermons. His subjects would be drawn from the Bible only,[48] especially from the New Testament, and he would follow the guidance of the Holy Spirit, and not human direction. So profound was the impression made by his impassioned and eloquent words that some of the listeners declared him to be a "new Moses who had arisen to save his people from spiritual bondage." The learned Platter writes that during the sermon he "felt himself lifted off the ground by his hair." The very first year of Zwingli's ministry at Zurich, two thousand souls were "saved by the milk of the Holy Gospel." And his practical goodness of heart was attested by his assiduous attention to the sick during the plague of 1519, in which he was himself stricken and brought very near to death. Three hymns composed during this trying time reveal his entire resignation and calm trust in God. Although he fiercely opposed the sale of indulgences there were no thunderings against him from the Vatican, such as were hurled against Luther.[49] The Eidgenossen, being useful to the Papal See, was rather indulged; it was even intimated to the Diet that they should send back from Bern Friar Bernhard Samson, who was preaching with great effect there, should he prove obnoxious. With unflagging zeal and courage Zwingli followed his ideal in politics, viz., to rear a republic on the type of the Greek free states of old, with perfect national independence. Thanks to his influence Zurich in 1521 abolished _Reislaufen_, and the system of foreign pay. This step, however, brought down on the head of Zurich the wrath of the twelve sister republics, which had just signed a military contract with Francis I. Zwingli addressed to Schwyz a "Holy Exhortation" to serve neither Pope nor Emperor; his exhortation, however, served only to increase the number of his political foes.[50] Relying rather on reason than on force, he prepared the way for his reforms with singular moderation and forbearance.
