A sound democracy, based on the immutable principles of the natural law and revealed truth, will resolutely turn its back on such corruption as gives to the state legislature in unchecked and unlimited power, and moreover, makes of the democratic regime, notwithstanding an outward show to the contrary, purely and simply a form of absolutism.
State absolutism consists in fact in the false principle that the authority of the state is unlimited and that in face of it — even when it gives free rein to its despotic aims, going beyond the confines between good and evil — to appeal to a higher law obliging in conscience is not admitted.
A man penetrated with right ideas about the state and authority and the power that he wields as guardian of social order, will never think of derogating the majesty of the positive law within the ambit of its natural competence. But this majesty of positive law is only inviolable when it conforms — or at least is not opposed — to the absolute order set up by the Creator and placed in a new light by the revelation of the Gospel.
