The result was that Philip was suspected of a tendency toward Zwinglianism. His sympathy for the Reformers associated with Zwingli in Switzerland and Bucer in Strasburg was intensified by the anger of the emperor at receiving from Philip a statement of Protestant tenets composed by the ex-Franciscan Lambert, and the landgrave's failure to secure any common action on the part of the Protestant powers regarding the approaching Turkish war. Philip eagerly embraced Zwingli's plan of a great Protestant alliance to extend from the Adriatic to Denmark to keep the Holy Roman Emperor from crossing into Germany. This association caused some coldness between himself and the followers of Luther at the Diet of Augsburg in 1530, especially when he propounded his irenic policy to Melanchthon and urged that all Protestants should stand together in demanding that a general council alone should decide religious differences. This was supposed to be indicative of Zwinglianism, and Philip soon found it necessary to explain his exact position on the question of the Eucharist, whereupon he declared that he fully agreed with the Lutherans, but disapproved of persecuting the Swiss.
