In recent years the religious skyline of Dutch cities has changed considerably. Besides traditional Protestant and Catholic churches new buildings of worship (e.g., mosques, Hindu and Buddist temples) have been built. Newly-established religions have contributed considerably to a religious diversification in society. How does law reflect these changes? Does it take this pluralism into account? Generally speaking, law always lags behind developments in society. There is a good reason for this: society as a whole has to adapt to these changes, and law, which is an institutional form of basic social norms, must moderate this adaptation. The presence of these newly or not established religions puts tolerance to the test: both the tolerance of society as a whole and the tolerance expressed in the law.
