Similar to Cicero, St Augustine considered natural law to be ‘almost divine’. In his book ‘City of God’ he wrote that real justice flows from eternal and objective standards of the natural law.
St Augustine believed that any law enacted that is objectively or socially undesirable then the government is no better than a criminal gang. ‘What are robberies but little kingdoms?’ he wrote.
This concept was motivated by two principles. First, unity derived from God; one faith, one church, and one empire. Second, ‘the supremacy of the law, not merely man-made, but conceived as a part of the unity of the universe’.
