Diuturnum §13

¹³ And it is impossible that any should be found not only more true but even more advantageous than this opinion. For the authority of the rulers of a State, if it be a certain communication of divine power, will by that very reason immediately acquire a dignity greater than human - not, indeed, that impious and most absurd dignity sometimes desired by heathen emperors when affecting divine honors, but a true and solid one received by a certain divine gift and benefaction. Whence it will behoove citizens to submit themselves and to be obedient to rulers, as to God, not so much through fear of punishment as through respect for their majesty; nor for the sake of pleasing, but through conscience, as doing their duty. And by this means authority will remain far more firmly seated in its place. For the citizens, perceiving the force of this duty, would necessarily avoid dishonesty and contumacy, because they must be persuaded that they who resist State authority resist the divine will; that they who refuse honor to rulers refuse it to God Himself.
