The death of his brother Walter (in World War I) and his mother’s desperate grief left an indelible mark on the child Dietrich Bonhoeffer. At his confirmation three years later, she gave him the Bible that Walter had received at his confirmation in 1914. Bonhoeffer used it throughout his life for his personal meditation and in worship.
