In his "History of France," renowned French historian Pierre Michel wrote that the reformation was a new idea in the Renaissance. Undoubtedly, it was the only centuries-old idea that had nothing to do with the Italians. It was rooted in France, in the profound disgust that inspired the Church in the desire for purification, but also in the desire of the Protestants to build a new, strong and free country, a state that owes nothing to the pope, nor to the King of Spain, and the Florentine bankers. The ideas of the Church Reformation are also coming soon into the spiritual life of the Francophone countries. Martin Luther's "Letter to the Pope" dates back to 1518. In the same year Bishop Brisole settled in the French city of Mo and began to spread Luther's teachings. It can be said that Lutheran ideas quickly traversed all of France, said Pierre Michel, found a favorable ground in these numerous intellectual communities formed around publishers and printers and enlightened members of the clergy.
Soon the French preachers continued Luther's trial. They spread the evangelical doctrine in many regions: Picardy, Normandy, the Paris region. Major cities like Lyon, like Paris, had their own evangelical circles. Everywhere "images", drawings and statues representing the Virgin and Saints were torn and destroyed. On the facades of many churches in Bree could be seen decapitated saints or virgins whose heads were hammered. The Reformers were singing psalms and hymns that served them as call signals. ". A preacher of the ideas of the Reformation in the French-speaking regions of Western Europe is the native of North France Jean Calvin. In 1521, Calvin received the Benevolence from the Church, devoted himself to the zealous study of literature and philosophy at two prestigious colleges in Paris - Marche, then followed right in Orléans and Burj. He is addicted to theological discussions and in 1533 joins the ideas of the Protestant Reformation thanks to his cousin Olivetan and the famous Renaissance erudite Lefivre d 'Yaples Rector of the University of Paris. Calvin participates in the defense of the composition of King Francois I's sister, Margarita of Navarra, "The Mirror of the Sinful Soul," which was condemned by Parliament after the Affiches. With the famous Affiches, loosed on October 18, 1534, in many French cities, the ideas of the Reformed Church, which was born in Germany, were announced. After the afficher affair, Calvin was forced to seek refuge in Basel, where he prepared the first version of his work, "Introduction to the Christian Religion," which he repeatedly reworked. It was published in Latin in 1539, and a little later, in 1541, it was published in French. Its full edition, which took place between 1559 and 1560, included 80 chapters. In the autumn of 1536, on his way to Strasbourg, Calvin passed through Geneva, whose Council of Bishops shortly before deciding to accept the Protestant religion. Employed to explain the ideas of the Reformed Church by Guillaume Farrell, he has made a lot of effort to impose them on the local population, but has encountered numerous difficulties.
During his first stay in Geneva, Calvin created the tract "Four Guides". Calvin's first works are geared towards the establishment and validation of the Reformed Church's dogma and discipline in Geneva. The rigidity and uncompromising norms introduced by Calvin provoked the hostility of the property bourgeois who succeeded in driving him out of town in 1538. At the urging of the local Council of 200 First Citizens, Calvin and Farrell are doomed to exile. Then the eminent church reformer went to Strasbourg where, during the period 1538-1541, he helped his conceptual mate in this town Martin Bucer. In 1540 he linked his life with the widowed Evelet of Bure. Called again in Geneva in 1541, Calvin lived until his death in this city, where he rapidly built the authority of a wise preacher and a highly respected spiritual mentor. On the insistence of a prestigious circle of influential citizens, he created the "Catechism of Geneva" and compiled a mandatory confession of the believer consisting of 21 assurances. His "preaching prescriptions" allow the Consistory, made up of pastors and laymen, to impose a strict spiritual discipline on the heterogeneous estrangement in the big city. Supported by France-expelled Protestants, Calvin manages to overcome the opposition of influential women's families who assert Catholicism. At the same time, Calvin's efforts are directed towards the convergence of the various Protestant Churches. He organized meetings between theologians who promoted the ideas of the Reformed Church in Frankfurt in 1539, in Worms in 1540, and in Ratsbisch in 1541. Calvin welcomed the ideas laid down in Melanchthon's "Augsburg Religion" (1530), which promoted the principles of lutheranism. Due to his increased authority, he exerts strong pressure on England's King Edward VI. This English ruler helps a lot for the convergence of the Anglican religion with Calvinism.
