 Voltaire wrote about Calvin , Luther and Zwingli , " If they condemned celibacy in the priests , and opened the gates of the convents , it was only to turn all society into a convent . Shows and entertainments were expressly forbidden by their religion ; and for more than two hundred years there was not a single musical instrument allowed in the city of Geneva . They condemned auricular confession , but they enjoined a public one ; and in Switzerland , Scotland , and Geneva it was performed the same as penance . "
