While at the Wartburg Castle, Luther’s foremost achievement was his translation of the New Testament into German.
Instead, the primary means of disseminating Luther’s ideas was the sermon. In city after city, the arrival of preachers presenting Luther’s teachings was soon followed by a pub-lic debate in which the new preachers proved victorious.
By the end of 1529, Charles was ready to deal with Germany. Though all owed loyalty to the emperor, Germany’s medieval development had enabled these states to become quite independent of imperial authority.
They had no desire to have a strong emperor.
Charles’s attempt to settle the Lutheran problem at the Diet of Augsburg in 1530 proved completely inadequate, and the emperor wound up demanding that the Lutherans return to the Catholic Church by April 15, 1531.
These Protestant German states vowed to assist each other ‘‘whenever any one of us is attacked on account of the Word of God and the doctrine of the Gospel.
The renewed threat of the Turks against Vienna forced Charles once again to seek compromise instead of war with the Protestant authorities.
From 1532 to 1535, Charles was forced to fight off an Ottoman, Arab, and Barbary attack on the Mediterranean coasts of Italy and Spain.
Two additional Habsburg-Valois Wars soon followed and kept Charles preoccupied with military campaigns in southern France and the Low Countries.
Finally, Charles made peace with Francis in 1544 and the Turks in 1545.
Fifteen years after the Diet of Augsburg, Charles was finally free to resolve his problem in Germany.
Charles brought a sizable imperial army of German, Dutch, Italian, and Spanish troops to do battle with the Protestants.
In the first phase of the Schmalkaldic Wars , the emperor’s forces decisively defeated the Lutherans at the Battle of Muhlberg .
Charles V was at the zenith of his power, and the Protestant cause seemed doomed.
This time Charles was less fortunate and had to negotiate a truce.
Exhausted by his efforts to maintain religious orthodoxy and the unity of his empire, Charles abandoned German affairs to his brother Ferdinand, abdicated all of his titles in 1556, and retired to his country estate in Spain to spend the remaining two years of his life in solitude.
Ulrich Zwingli was a product of the Swiss forest cantons.
The precocious son of a relatively prosperous peasant, the young Zwingli eventually obtained both bachelor of arts and master of arts degrees.
During his university education at Vienna and Basel, Zwingli was strongly influenced by Christian humanism.
Ordained a priest in 1506, he accepted a parish post in rural Switzerland until his appointment as a cathedral priest in the Great Min-ster of Zu ̈rich in 1518.
Through his preaching there, Zwingli began the Reformation in Switzerland. Zwingli’s preaching of the Gospel caused such unrest that in 1523 the city council held a public dispute or debate in the town hall.
He adhered to the doctrine of justification by faith alone to explain how humans achieved salvation.
Calvin also placed much emphasis on the absolute sovereignty of God or the ‘‘power, grace, and glory of God.
This ‘‘eternal decree,’’ as Calvin called it, meant that God had predestined some people to be saved and others to be damned .
According to Calvin, ‘‘He has once for all determined, both whom he would admit to salvation, and whom he would condemn to destruction.
In no instance did Calvin ever suggest that worldly success or material wealth was a sign of election.
Significantly for the future of Calvinism, although Calvin himself stressed that there could be no absolute certainty of salvation, some of his followers did not always make this distinction.
To Calvin, the church was a divine institution responsible for preaching the word of God and administering the sacra-ments.
Calvin kept the same two sacraments as other Protestant reformers, baptism and the Lord’s Supper.
Jesus’s body is at the right hand of God and thus cannot be in the sacrament, but to the believer, Jesus is spiritually present in the Lord’s Supper.
Before 1536, John Calvin had essentially been a scholar. But in that year, he took up a ministry in Geneva that lasted, except for a brief exile , until his death in 1564.
Calvin achieved a major success in 1541 when the city council accepted his new church constitution, known as the Ecclesiastical Ordinances.
During Calvin’s last years, stricter laws against blasphemy were enacted and enforced with banishment and public whippings.
Calvin’s success in Geneva enabled the city to become a vibrant center of Protestantism. ’’ Following Calvin’s lead, missionaries trained in Ge-neva were sent to all parts of Europe.
Calvinism became established in France, the Netherlands, Scotland, and central and eastern Europe.
By the mid-sixteenth century, Calvinism had replaced Lutheranism as the international form of Protestantism, and Calvin’s Geneva stood as the fortress of the Reformation.
