The three major Middle Eastern religions are significantly different in their relations with the state and their attitudes to political power. Judaism was associated with the state and was then disentangled from it; its new encounter with the state at the present time raises problems which are still unresolved. Christianity, during the first formative centuries of its existence, was separate from and indeed antagonistic to the state with which it only later became involved. Islam from the lifetime of its founder the state, and the identity of religion and government is indelibly stamped on the memories and awareness of the faithful from their own sacred writings, history, and experience.
