The rule of law is the legal principle that law should govern a nation, as opposed to being governed by arbitrary decisions of individual government officials. It primarily refers to the influence and authority of law within society, particularly as a constraint upon behaviour, including behaviour of government officials. The phrase can be traced back to 16th century Britain, and in the following century the Scottish theologian Samuel Rutherford used the phrase in his argument against the divine right of kings. The rule of law was further popularized in the 19th century by British jurist A. V. Dicey. The concept, if not the phrase, was familiar to ancient philosophers such as Aristotle, who wrote "Law should govern".
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Which Scottish theologian is first credited with using the phrase "rule of law"?
Samuel Rutherford
