The Secret of Saint John Bosco likely refers to the book by Henri Gheon, translated by F.J. Sheed, which tells the story of Saint John Bosco, a 19th-century Italian priest dedicated to helping marginalized youth. The book explores his life, work, and the methods he used to guide young people away from vice and towards faith. The 'secret' in the title might allude to the unique approach Saint John Bosco used, which involved a combination of prayer, action, and a deep love for young people. He believed that work and prayer were not separate but intertwined, and that even seemingly simple activities like acrobatic performances could be a form of prayer. He attributed his success to the Virgin Mary, often stating, I have been an instrument in the hands of Mary. She has done everything.
