18 Those twelve disciples who had been the first to place themselves under his government were like a small seed, which by the grace of God, and under the fostering care of the Sovereign Pontiff, quickly became an abundant harvest. After having holily instructed them in the school of Christ, he allotted to them for the preaching of the Gospel the various parts of Italy and of Europe; and some he sent even as far as Africa. There was no delay; poor, ignorant, unrefined, they mingled with the people: in the highways and in the public squares, with no preparation of place or pomp of rhetoric, they set themselves to exhort men to despise earthly things and to think of the time to come. It is marvellous to see the fruits produced by the enterprise of such workers, apparently so inadequate. Crowds gathered round them, eager to hear them: faults were bitterly bewept, injuries were forgotten, and sentiments of peace were reintroduced by the appeasing of discords.
