Luke 5:28

The profane Julian charge St. Matthew with levity, in leaving all and following a stranger at one word. But hereby is seen the marvellous efficacy of Christ's word and internal working, which in a moment can alter the heart of man, and cause him to despise what before was most near and dear to him. And this was done not only whilst Christ was living on earth, but daily in his Church. Thus St. Anthony, St. Francis, and others, hearing this word in the Church, forsook all and followed Jesus. (St. Jerome, in Matt. ix.; St. Athanasius, in vita. St. Anthony; St. Augustine, Confess. lib. viii. chap. 11.; St. Bonaventure, in vit. St. Francis.)
