“As physicians always have their instruments and knives ready for cases that suddenly require their skill, so do you have principles ready for the understanding of things divine and human, and for doing everything, even the smallest, with a recollection of the bond that unites the divine and the human to each other. For neither can you do anything well that pertains to man without at the same time having a reference to things divine; nor the contrary.”
