The greatness of some men only makes us feel that though they did well, others in their place might have done just as they did: Luther had that exceptional greatness, which convinces the world that he alone could have done the work. He was not a mere mountain-top, catching a little earlier the light beams which, by their own course, would soon have found the valleys; but rather, by the divine ordination under which he rose, like the sun itself, without which the light on mountain and valley would have been starlight or moonlight. He was not a secondary orb; reflecting the light of another orb, as was Melanchthon, and even Calvin; still less the moon of a planet, as Bucer or Brentius; but the centre of undulations which filled a system with glory.
