Jesus came to save both the poor and the rich, both the peasant and the prince. But when it came to selection of his apostles, he did not choose princes or the wealthy or the learned or those of noble birth. Instead, he chose fishermen, simple people through whom his grace could shine most clearly. If he had first called a king, the king might have thought it was because of his regal position that he had been chosen. If he had first called a scholar, he might have thought it was because of his brains that he had been chosen. To call the world to humility, the message had to be carried by humble people. And so it was that Christ did not convert fishermen through an emperor but an emperor through a fisherman.

–Augustine, Sermon 360B.24
