Lutheran orthodoxyLutheran orthodoxy was an era in the history of Lutheranism, which began in 1580 from the writing of the Book of Concord and ended at the Age of Enlightenment. Lutheran orthodoxy was paralleled by similar eras in Calvinism and tridentine Roman Catholicism after the Counter-Reformation. Lutheran scholasticism was a theological method that gradually developed during the era of Lutheran orthodoxy. Theologians used the neo-Aristotelian form of presentation, already popular in academia, in their writings and lectures.
Book of ConcordThe Book of Concord (1580) or Concordia (often referred to as the Lutheran Confessions) is the historic doctrinal standard of the Lutheran Church, consisting of ten credal documents recognized as authoritative in Lutheranism since the 16th century. They are also known as the symbolical books of the Evangelical Lutheran Church. The Book of Concord was published in German on June 25, 1580, in Dresden, the fiftieth anniversary of the presentation of the Augsburg Confession to Emperor Charles V at the Diet of Augsburg.
Protestant work ethicThe Protestant work ethic, also known as the Calvinist work ethic or the Puritan work ethic, is a work ethic concept in scholarly sociology, economics, and historiography. It emphasizes that diligence, discipline, and frugality are a result of a person's subscription to the values espoused by the Protestant faith, particularly Calvinism. The phrase was initially coined in 1905 by Max Weber in his book The Protestant Ethic and the Spirit of Capitalism.
Cell groupThe cell group is a form of church organization that is used in many Christian churches. Cell groups are generally intended to teach the Bible and personalize Christian fellowship. They are always used in cell churches, but also occur in parachurch organizations and other interdenominational settings, where they are usually referred to as such as Bible study groups. In Methodism, they are known as class meetings and are a means of grace; in Catholicism, they are known as basic ecclesial communities.
