Gospel had to maintain in the palace of the dukes of Este. One of the duchess's ladies—her name is not known—who had found peace with God in the Saviour's death, refused to be present at mass. François attempted to convince her, but the young lady remained firm as a rock. 'She would not offend her conscience.' The angry priest complained to the duchess and did all in his power to deprive the young maid of honor of the kindly feeling which Renée was accustomed to show towards her. Before long the duchess herself was 'warned,' that those who 'conducted themselves like that young lady' would not be tolerated, seeing that they would give occasion for scandal. The princess, knowing full well that the duke would not permit any one at court to reject the mass, was in great distress, and Calvin was informed of it by the countess of Marennes.[797] The enemies of the Reformation added falsehood to violence. The confessor tried to make the duchess believe that the churches of Germany had not discussed the matter, but that they admitted the mass. Calvin complained loudly of the great injury done to the churches of God. 'All the churches that have received the Gospel,' he wrote a little later, 'and even all individuals hold this article—that the mass ought not to be endured. Even Capito, one of those who endeavors earnestly to _moderate_ matters, teaches in a work dedicated to the king of England, that it is the duty of Christian princes to drive from their realms such a detestable idolatry. There is now not a single man of reputation who is not of that opinion.'[798] [Sidenote: CALVIN WRITES TO DUCHEMIN.]
