The Prison Meditations of Father Delp is a collection of reflections by Alfred Delp, a German Jesuit priest executed by the Nazis during World War II. Written while imprisoned for his involvement in the Kreisau Circle resistance group, the meditations offer a profound commentary on faith, suffering, and the challenge of living a "God-conscious humanism" in a modern, faithless society. The book includes an introduction by Thomas Merton and covers themes of spiritual renewal, the nature of true faith, and the need for both inner transformation and social responsibility.
