Chesterton on Saints

"The saint is a medicine because he is an antidote. Indeed that is why the saint is often a martyr; he is mistaken for a poison because he is an antidote. He will generally be found restoring the world to sanity by exaggerating whatever the world neglects, which is by no means always the same element in every age. Yet each generation seeks its saint by instinct; and he is not what the people want, but rather what the people need. . . . Therefore it is the paradox of history that each generation is converted by the saint who contradicts it most."
G.K. Chesterton
