"In history, systems of law have almost always been based on religion: decisions regarding what was to be lawful among men were taken with reference to the divinity. Unlike other great religions, Christianity has never proposed a revealed law to the State and to society, that is to say a juridical order derived from revelation. Instead, it has pointed to nature and reason as the true sources of law" („Address of His Holiness Pope Benedict XVI to the Reichstag”. Приступљено 2019-12-16.).
