###Input: Despite the disagreements on the Eucharist, the Marburg Colloquy paved the way for the signing in 1530 of the Augsburg Confession, and for the formation of the Schmalkaldic League the following year by leading Protestant nobles such as John of Saxony, Philip of Hesse, and George, Margrave of Brandenburg-Ansbach. The Swiss cities, however, did not sign these agreements.

Some scholars have asserted that Luther taught that faith and reason were antithetical in the sense that questions of faith could not be illuminated by reason. He wrote, "All the articles of our Christian faith, which God has revealed to us in His Word, are in presence of reason sheerly impossible, absurd, and false." and "[That] Reason in no way contributes to faith. [...] For reason is the greatest enemy that faith has; it never comes to the aid of spiritual things." However, though seemingly contradictorily, he also wrote in the latter work that human reason "strives not against faith, when enlightened, but rather furthers and advances it", bringing claims he was a fideist into dispute. Contemporary Lutheran scholarship, however, has found a different reality in Luther. Luther rather seeks to separate faith and reason in order to honor the separate spheres of knowledge that each applies to. Bernhard Lohse, for example, has demonstrated in his classic work "Fides und Ratio" that Luther ultimately sought to put the two together. More recently, Hans-Peter Grosshans has demonstrated that Luther's work on Biblical Criticism stresses the need for external coherence in the right exegetical method. This means that for Luther it is more important that the Bible is reasonable according to the reality outside of the scriptures than that the Bible makes sense to itself, that it has internal coherence. The right tool for understanding the world outside of the Bible for Luther is none other than reason, which for him is the field of science, philosophy, history and empirical observation. Here a different picture is presented of a Luther who deeply valued both faith and reason, and held them in dialectical partnership. Luther's concern thus in separating them is honoring their different epistemological spheres.

In 1523, Luther wrote that Jesus Christ was born a Jew which discouraged mistreatment of the Jews and advocated their conversion by proving that the Old Testament could be shown to speak of Jesus Christ. However, as the Reformation continued, Luther began to lose hope in large-scale Jewish conversion to Christianity. In his later years, Luther grew more hostile toward the Jews, writing against them with the kind of venom he had already unleashed on the Anabaptists, Zwinglianism, and the papacy. His 1543 treatise Von den Juden und ihren Lügen (On the Jews and Their Lies) took its place among other anti-Jewish literature of the times, although historians acknowledge that this treatise was particularly extreme, even by the standards of sixteenth century Europe. In it, he takes a hardline against Judaism, writing that synagogues and Jewish homes should be destroyed, their money confiscated, and liberty curtailed. These statements and their influence on antisemitism have contributed to his controversial status.

At the time of the Marburg Colloquy, Suleiman the Magnificent was besieging Vienna with a vast Ottoman army. Luther had argued against resisting the Turks in his 1518 Explanation of the Ninety-five Theses, provoking accusations of defeatism. He saw the Turks as a scourge sent to punish Christians by God, as agents of the Biblical apocalypse that would destroy the antichrist, whom Luther believed to be the papacy, and the Roman Church. He consistently rejected the idea of a Holy War, "as though our people were an army of Christians against the Turks, who were enemies of Christ. This is absolutely contrary to Christ's doctrine and name". On the other hand, in keeping with his doctrine of the two kingdoms, Luther did support non-religious war against the Turks. In 1526, he argued in Whether Soldiers can be in a State of Grace that national defence is reason for a just war. By 1529, in On War against the Turk, he was actively urging Emperor Charles V and the German people to fight a secular war against the Turks. He made clear, however, that the spiritual war against an alien faith was separate, to be waged through prayer and repentance. Around the time of the Siege of Vienna, Luther wrote a prayer for national deliverance from the Turks, asking God to "give to our emperor perpetual victory over our enemies".

In 1542, Luther read a Latin translation of the Qur'an. He went on to produce several critical pamphlets on Islam, which he called "Mohammedanism" or "the Turk". Though Luther saw the Muslim faith as a tool of the devil, he was indifferent to its practice: "Let the Turk believe and live as he will, just as one lets the papacy and other false Christians live." He opposed banning the publication of the Qur'an, wanting it exposed to scrutiny.
