Politics in Minutes (2016)
The connection between politics and religion runs very deep. Religions have provided societies with the moral code that underpins their laws. In many cases, there is a predominant religion in a country that is intrinsic to its national identity and cultural heritage, even if it is now only practised by a minority of the population. The United Kingdom, for example, is often considered a ‘Christian country’ despite its multicultural make-up.
Some faiths are endorsed as official, state religions, in a similar way to the adoption of a language as the official language. This may be a formal acknowledgement that gives little or no real status to the religion or its clerics, where the religion plays a purely ceremonial role, or where representatives of the faith may play some part in the secular government. Today, most countries with a state religion are Islamic, but there are some countries, notably the UK, which have retained an established Christian church.
