Bible only is infallible. Every Christian can interpret it. Human sins are so wrongful that no deed or merit, only God's grace, can lead to salvation. In consequence, Luther hoped to stop the sale of indulgences and to reform the Church from within. In 1521, he was given the chance to recant at the Diet of Worms before Charles V, Holy Roman Emperor. After he refused to recant, he was declared heretic. Partly for his own protection, he was sequestered on the Wartburg in the possessions of Frederick III, Elector of Saxony, where he translated the New Testament into German. He was excommunicated by papal bull in 1521. However, the movement continued to gain ground in his absence and spread to Switzerland. Huldrych Zwingli preached reform in Zürich from 1520 to 1523. He opposed the sale of indulgences, celibacy, pilgrimages, pictures, statues, relics, altars, and organs. This culminated in outright war between the Swiss cantons that accepted Protestantism and the Catholics. In 1531, the Catholics were victorious, and Zwingli was killed in battle. The Catholic cantons made peace with Zurich and Berne. The defiance of papal authority proved contagious, and in 1533, when Henry VIII of England was excommunicated for his divorce and remarriage to Anne Boleyn, he promptly established a state church with bishops appointed by the crown. This was not without internal opposition, and Thomas More, who had been his Lord Chancellor, was executed in 1535 for opposition to Henry. In 1535, the Swiss canton of Geneva became Protestant. In 1536, the Bernese imposed the reformation on the canton of Vaud by conquest. They sacked the cathedral in Lausanne and destroyed all its art and statuary. John Calvin, who had been active in Geneva was expelled in 1538 in a power struggle, but he was invited back in 1540. The same kind of seesaw back and forth between Protestantism and Catholicism was evident in England when Mary I of England returned that country briefly to the Catholic fold in 1553 and persecuted Protestants. However, her half-sister, Elizabeth I of England was to restore the Church of England in 1558, this time permanently, and began to persecute Catholics again. The King James Bible commissioned by King James I of England and published in 1611 proved a landmark for Protestant worship, with official Catholic forms of worship being banned. In France, although peace was made between Protestants and Catholics at
