A
shared church (
German:
Simultankirche),
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.
[1] The different Christian
denominations (such as
Roman Catholic,
Lutheran,
Reformed, or
United, etc.), share the same
church building, although they worship at different times and with different
clergy. It is thus a form of
religious toleration.

Simultaneum as a policy was particularly attractive to 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
