The role of religion as a contentious and motivating force in society is examined here through the lens of the church-state dynamic in countries with three very different approaches to this crucial relationship. Focusing on the United Kingdom, where there is official recognition of one religion by the state, the United States, where law imposes a separatism between religion and the state and Germany, where there is cooperation between the church and state, this book compares these three models. It describes the components of each model, illustrates their operation and uses case law to examine what each model might learn from the other. Controversial and timely issues such as the refusal of medical treatment on religious grounds, the wearing of Islamic headscarves and ritual animal slaughter are discussed with new insight, providing a comprehensive review of varied approaches to law, government and religious freedom.
