German Confessing Church

The Confessing Church (also translated Confessional Church) (German: Bekennende Kirche) was a movement within German Protestantism during Nazi Germany that arose in opposition to government-sponsored efforts to unify all Protestant churches into a single pro-Nazi Protestant Reich Church.

The following statistics (as of January 1933 unless otherwise stated) are an aid in understanding the context of the political and theological developments discussed in this article.

After the Peace of Augsburg in 1555, the principle that the religion of the ruler dictated the religion of the ruled (cuius regio, eius religio) was observed throughout the Holy Roman Empire. § 24 of the Peace of Augsburg (ius emigrandi) guaranteed members of denominations other than the ruler's the freedom of emigration with all their possessions. Political stalemates among the government members of different denominations within a number of the republican free imperial cities such as Augsburg, the Free City of Frankfurt, and Regensburg, made their territories de facto bi-denominational, but the two denominations did not usually have equal legal status.

The Peace of Augsburg protected Catholicism and Lutheranism, but not Calvinism. Thus, in 1613, when John Sigismund, Elector of Brandenburg converted from Lutheranism to Calvinism, he could not exercise the principle of cuius regio, eius religio. This situation paved the way for bi- or multi-denominational monarchies, wherein a ruler adhering to a creed different from most of his subjects would permit conversions to his minority denomination and immigration of his fellow faithful. In 1648, the Peace of Westphalia accorded the principle of cuius regio, eius religio also to Calvinism.

However, the principle grew impracticable in the 17th and 18th centuries, which experienced continuous territorial changes arising from annexations and inheritances, and the religious conversion of rulers. For instance, Saxon Augustus II the Strong converted from Lutheranism to Catholicism in 1697, but did not exercise his cuius regio, eius religio privilege. A conqueror or successor to the throne who adhered to a different creed from his new subjects usually would not complicate his takeover by imposing conversions. These enlarged realms spawned diaspora congregations, as immigrants settled in areas where the prevailing creeds differed from their own. This juxtaposition of beliefs in turn brought about more frequent personal changes in denomination, often in the form of marital conversions.
