III. Scriptural examples of humility
Of this high-souled humility the Apostles first, after the Lord, have given us example, who, leaving all that they had without difference at the voice of the heavenly Master, were turned by a ready change from the catching of fish to be fishers of men, and made many like themselves through the imitation of their faith, when with those first-begotten sons of the Church, “the heart of all was one, and the spirit one, of those that believed:” for they, putting away the whole of their things and possessions, enriched themselves with eternal goods, through the most devoted poverty, and in accordance with the Apostles' preaching rejoiced to have nothing of the world and possess all things with Christ.
Hence the blessed Apostle Peter, when he was going up into the temple, and was asked for alms by the lame man, said, “Silver and gold is not mine, but what I have that I give you: in the Name of Jesus Christ of Nazareth, arise and walk.” What more sublime than this humility? What richer than this poverty? He has not stores of money, but he has gifts of nature. He whom his mother had brought forth lame from the womb, is made whole by Peter with a word; and he who gave not Cæsar's image in a coin, restored Christ's image on the man.
And by the riches of this treasure not he only was aided whose power of walking was restored, but 5,000 men also, who then believed at the Apostle's exhortation on account of the wonder of this cure. And that poor man who had not what to give to the asker, bestowed so great a bounty of Divine Grace, that, as he had set one man straight on his feet, so he healed these many thousands of believers in their hearts, and made them “leap as an hart” in Christ whom he had found limping in Jewish unbelief.
