The "Lord's Prayer" is one of the most well-known writings of Romano Guardini. A masterful language, an inner closeness to the Holy Scriptures, and a vibrant faith that deeply shapes one's own existence characterize his thoughts. The plea "Thy will be done" serves as the guiding principle of this book. In eleven reflections, Guardini explores the Our Father and its petitions. He also acknowledges the great Christian thinkers and pray-ers who have dedicated themselves to the interpretation of this prayer since the early centuries.
