History is not a creed or a catechism, it gives lessons rather than rules; still no one can mistake its general teaching in this matter, whether he accept it or stumble at it. Bold outlines and broad masses of color rise out of the records of the past. They may be dim, they may be incomplete; but they are definite. And this one thing at least is certain; whatever history teaches, whatever it omits, whatever it exaggerates or extenuates, whatever it says and unsays, at least the Christianity of history is not Protestantism. If ever there were a safe truth, it is this.
–Blessed John Henry Newman (1801-1890)
