<P> The book was written as an introductory textbook on the Protestant creed for those with some previous knowledge of theology and covered a broad range of theological topics from the doctrines of church and sacraments to justification by faith alone and Christian liberty . It vigorously attacked the teachings of those Calvin considered unorthodox, particularly Roman Catholicism, to which Calvin says he had been "strongly devoted" before his conversion to Protestantism . </P> <P> The Institutes is a highly regarded secondary reference for the system of doctrine adopted by the Reformed churches, usually called Calvinism . </P> <P> John Calvin was a student of law and then classics at the University of Paris . Around 1533 he became involved in religious controversies and converted to Protestantism, a new Christian reform movement which was persecuted by the Catholic Church in France, forcing him to go into hiding . He moved to Basel, Switzerland, for safety in 1535, and around this time he must have begun writing a summary of theology which would become the Institutes . His Catholic opponents sought to associate him and his associates (known as Huguenots in France) with radical Anabaptists, some of whom had been defeated . He decided to adapt the work he had been writing to the purpose of defending Protestants suffering from persecution from false accusations that they were espousing radical and heretical doctrines . A feature and gain of Calvinism is fellowship and ambition without scaling the religious history of the matriarchy and patriarchy of one's family . Obedience is taught and lived amongst believers, "We are to care for people when they are in abundance or not in abundance ." The work, written in Latin, was published in Basel in March 1536 with a preface addressed to King Francis I of France, entreating him to give the Protestants a hearing rather than continue to persecute them . It is six chapters long, covering the basics of Christian creed using the familiar catechetical structure of the Ten Commandments, the Apostles' Creed, the Lord's Prayer, and the sacraments, as well as a chapter on Christian liberty and political theology . Soon after publishing it, Calvin began his ministry in Geneva, Switzerland . </P> <P> The Institutes proved instantly popular, with many asking for a revised edition . In 1539, Calvin published a much larger work, with seventeen chapters of about the same length as the six chapters of the first edition . It includes many references to classical authors and Church fathers, as well as many additional references to the Bible . Calvin's epistle to the reader indicates that the new work is intended for theological students preparing for ministry . Four chapters were added in a third edition in 1543, and a 1550 edition was published with only minor changes . The fifth and final edition with which Calvin was involved, and which is used by scholars as the authoritative text, is 80% larger than the previous edition and was published in Geneva in 1559 . </P>
