"The souls of pious persons are so strongly affected in reading them, that they always lay down the book with regret. This every one may experience in himself. I with truth aver, that there is nothing in the whole history of the church with which I am so much moved: when I read them I seem no longer to possess myself." It would be very easy to compile a volume of the remarkable testimonies of eminent and holy men concerning this most powerful help to virtue, and to produce many examples of sinners, who have been converted by it to an heroic practice of piety. St. Austin mentions two courtiers who were moved on the spot to forsake the world, and became fervent monks, by accidentally reading the life of St. Antony.[11] St. John Columbin, from a rich, covetous, and passionate nobleman, was changed into a saint, by casually reading the life of St. Mary of Egypt.[12] The duke of Joyeuse, marshal of France, owed his perfect conversion to the reading of the life of St. Francis Borgia, which his servant had one evening laid on the table. To these the example of St. Ignatius of Loyola, and innumerable others might be added. Dr. Palafox, the pious Binni of Osma, in his preface to the fourth tome of the letters of St. Teresa, relates, that an eminent Lutheran minister at Bremen, famous for several works which he had printed against the Catholic church, purchased the life of St. Teresa, written by herself, with a view of attempting to confute it; but, by attentively reading it over, was converted to the Catholic faith, and from that time led a most edifying life. The examples of Mr. Abraham Woodhead and others were not less illustrious.
