[RobbyS]

The Syllabus never denies the utility of democracy, only the validity of absolute claims of its authority. For in truth, one can never know what the actual source of a particular claim is. For instance, where the source of the authority of a legislature to make law on any mattter whatever so ever? Is not a majority vote as arbitary as an edict by the Executive? Is not a court order equally so?

[John Locke]

Perhaps this will help answer your question:

"Such is the rush of present-day life that it severs from the divine foundation of Revelation, not only morality, but also the theoretical and practical rights.

We are especially referring to what is called the natural law, written by the Creator's hand on the tablet of the heart [Romans ii:14] and which reason, not blinded by sin or passion, can easily read. It is in the light of the commands of this natural law, that all positive law, whoever be the lawgiver, can be gauged in its moral content, and hence, in the authority it wields over conscience.

Human laws in flagrant contradiction with the natural law are vitiated with a taint which no force, no power can mend."

[Pius XI, Encyclical mit brennender Sorge, 1937 March 14]
