“A Church which embraced, with equal sympathy, and within a hundred years, the Virgin, Saint Bernard, William of Champeaux and the School of Saint Victor, Peter the Venerable, Saint Francis of Assisi, Saint Dominic, Saint Thomas Aquinas, and Saint Bonaventure, was more liberal than any modern state can afford to be. Radical contradictions the State may perhaps tolerate, but never embrace or profess. Such elasticity long ago vanished from human thought.”

Henry Adams (1838–1918) journalist, historian, academic, novelist
