After the death of Luther came the period of the Schmalkaldic War and disputes among Crypto-Calvinists, Philippists, Sacramentarians, Ubiquitarians, and Gnesio-Lutherans.
The Book of Concord gave inner unity to Lutheranism, which had many controversies, mostly between Gnesio-Lutherans and Philippists, in Roman Catholic outward pressure and in alleged "crypto-Calvinistic" influence.
Lutheran scholasticism developed gradually, especially for the purpose of disputation with the Jesuits, and it was finally established by Johann Gerhard (1582–1637).
[6] The usual order of the loci:[5] High Scholasticism in Western Christianity aimed at an exhaustive treatment of theology, supplementing revelation by the deductions of reason.
[4] Around the time he became a monk, Luther sought assurances about life, and was drawn to theology and philosophy, expressing particular interest in Aristotle and the scholastics William of Ockham and Gabriel Biel.
[7] He was deeply influenced by two tutors, Bartholomaeus Arnoldi von Usingen and Jodocus Trutfetter, who taught him to be suspicious of even the greatest thinkers,[7] and to test everything himself by experience.
In particular, Luther wrote theses 43 and 44 for his student Franz Günther to publicly defend in 1517 as part of earning his Baccalaureus Biblicus degree:[9]It is not merely incorrect to say that without Aristotle no man can become a theologian; on the contrary, we must say: he is no theologian who does not become one without AristotleMartin Luther held that it was "not at all in conformity with the New Testament to write books about Christian doctrine."
He noted that before the Apostles wrote books, they "previously preached to and converted the people with the physical voice, which was also their real apostolic and New Testament work.
[12] In contrast, Philipp Melanchthon scarcely began to lecture on Romans before he decided to formulate and arrange the definitions of the common theological terms of the epistle in his Loci Communes.
When he felt ready to move on, he turned his attention to reading through the early theologians of the church slowly and carefully.
He understood biblical revelation to be progressive—building from the earlier books to the later ones—and examined his supporting texts in their literary contexts and historical settings.
[19] Instead, Lutheran dogmaticians used syllogistic arguments and the philosophical terms common in the neo-Aristotelianism of the time to make fine distinctions and enhance the precision of their theological method.
Second, they completed their process by going back to the pre-Reformation scholastics in order to gather additional material which they assumed the Reformation also accepted.
[4] However the 20th century Lutheran scholar Robert Preus was of the opinion that König went overboard with the scholastic method by overloading his small book, Theologia Positiva Acroamatica with Aristotelian distinctions.
[6] On the other hand, the Lutheran scholastic method, although often tedious and complicated, managed to largely avoid vagueness and the fallacy of equivocation.
It is also worth noting that it was only after neo-Aristotelian philosophical methods were ended that orthodox Lutheranism came to be criticized as austere, non-Christian formalism.
[4] Henry Eyster Jacobs writes of the scholastic method: Congregations maintained the full Mass rituals in their normal worship as suggested by Luther.
[30] Some hymnwriters include Philipp Nicolai, Johann Heermann, Johann von Rist and Benjamin Schmolck in Germany, Haquin Spegel in Sweden, Thomas Hansen Kingo in Denmark, Petter Dass in Norway, Hallgrímur Pétursson in Iceland, and Hemminki Maskulainen in Finland.
[31][32] Generally, the 17th century was a more difficult time than the earlier period of Reformation, due in part to the Thirty Years' War.
More recently, a number of social historians, as well as historical theologians, have brought Lutheran orthodoxy to the forefront of their research.
These scholars have expanded the understanding of Lutheran orthodoxy to include topics such as preaching and catechesis, devotional literature, popular piety, religious ritual, music and hymnody, and the concerns of cultural and political historians.
Lutheran orthodoxy can also be reflected in such rulers as Ernst I, Duke of Saxe-Coburg-Altenburg and Gustavus Adolphus of Sweden.
