However, in the preface, Werfel states that readers will justifiably ask "What is true and what is invented?" Werfel answers: "All the memorable happenings that constitute the substance of this book took place in the world of reality. Since their beginning dates back no longer than eighty years at the time Werfel wrote the book, there beats upon them the bright light of modern history and their truth has been confirmed by friend and foe and by cool observers through faithful testimonies. My story makes no changes in this body of truth. I exercised my right of creative freedom only where the work, as a work of art, demanded certain chronological condensations or where there was need of striking the spark of life from the hardened substance." He declares: ""The Song of Bernadette" is a novel but not a fictive work."
