In consequence of this turn of events at the Diet of 1556-1557, the papal legate, Lippomano, immediately left Poland for Rome. There he complained of the lack of religious fervor and zeal on the part of the Polish hierarchy, attributing to their religious indifference the vigorous growth of Protestantism in Poland, and of the king that he was permitting everyone to believe and to worship as he pleased.[160] His complaint of the Polish bishops was not altogether groundless. How little they apparently cared for the spiritual welfare of the church is shown by their attendance at the synod of 1557, which met at Piotrków on May 17. Besides the archbishop of Gnesen, there were present two bishops only, Zebrzydowski, bishop of Cracow, and Uchański, bishop of Chełm. The other bishops were represented by their delegates. Moreover, one of the bishops present, Uchański, asked his colleagues to vote at the next Diet for the introduction into the Polish church of communion of both kinds. But the delegates of the cathedral chapters opposed this suggested innovation most decidedly, and turned it down.[161] Meanwhile the Reformation was making steady progress, not only in the possessions of the szlachta, but also in cities and among government officials. And owing to the fact that Protestants were now found among senators, starostas, royal court officials, and among the king’s most intimate friends, punishment of heretics was becoming increasingly more difficult.[162] In Little Poland the Calvinistic churches had become so numerous that for administrative purposes they were divided in 1560 into districts, over which superintendents were appointed both clerical and lay,--clerical, to care for the spiritual welfare of the churches, and lay, for the administration of temporal affairs. At the joint synod of the Calvinists and the Bohemian Brethren at Włodzisław, on June 15, 1557, on motion of the distinguished reformer John Łaski, it was decided that steps be taken to effect a union with the Lutherans, such as had previously been effected between the Calvinists of Little Poland and the Bohemian Brethren of Great Poland.[163]
