Sách nói: Venerable Don Bosco the Apostle of Youth

This brief sketch of the holy life and marvelous achievements of a great inheritor of the spirit of Saint Francis of Sales, Saint Don Bosco is intended only to stimulate souls to a wider study of this loving Apostle of Youth, and so to a knowledge and reverence and appreciation, we dare to hope, which will urge them onward in the ways of holiness, and make them ardent and practical co-operators in the divine work of saving the young — the most pressing need of our times — initiated by the Founder of the Salesian Society, and brought to wonderful issues through the miraculous power of God and the loving intervention of Mary, Help of Christians.

Saint John Bosco was canonized in 1934 – thus in this book, which was published in 1916, he in only referred to as Venerable. (Summary adapted from the forward of the book)
