Simultaneum


A shared church, simultaneum mixtum, a term first coined in 16th-century Germany, is a church in which public worship is conducted by adherents of two or more religious groups. Such churches became common in the German-speaking lands of Europe in the wake of the Protestant Reformation. The different Christian denominations, share the same church building, although they worship at different times and with different clergy. Simultaneums have been seen as a manifestation of Christian ecumenism.
Simultaneum as a policy was particularly attractive to Christian rulers who ruled over populations which contained considerable numbers of both Catholics and Protestants. It was often the opposite of cuius regio, eius religio and used in situations where a ruler was of a different religion than the majority of the people, and not strong enough to impose his religion on the population. These have been seen as a form of religious toleration.
During the Nine Years' War, Louis XIV of France occupied the Electorate of the Palatinate, a Protestant region situated mainly in the western part of what is today Germany, where he introduced the simultaneum. At the end of the war the region returned to Protestant control, but a last-minute addition to the Treaty of Ryswick provided for a continuation of the simultaneum. Although intended to apply only to the Palatinate, the simultaneum was subsequently also applied in portions of Protestant Alsace.

Holy Land church-sharing

The main traditional pilgrim churches of Jerusalem and Bethlehem are shared between several denominations. The regulatory work is known as the "Status quo", a type of church-sharing which is in no way related to the West European Protestant-Catholic sharing system described here.
