If a worker is deprived of hope to acquire some personal property, what other natural stimulus can be offered him that will inspire him to hard work, labor, saving and sobriety today, when so many nations and men have lost everything and all they have left is their capacity for work?
Pope Pius XIIHenceforth it will be the task of this Sacred Congregation not only to examine carefully the books denounced to it, to prohibit them if necessary, and to grant permission for reading forbidden books, but also to supervise, ex officio, books that are being published, and to pass sentence on such as deserve to be prohibited.
Pope Pius XIIPrivate property is a natural fruit of labor, a product of intense activity of man, acquired through his energetic determination to ensure and develop with his own strength his own existence and that of his family, and to create for himself and his own an existence of just freedom, not only economic, but also political, cultural and religious.
Pope Pius XII
