Private 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"Render unto Caesar the things which are Caesar's and unto God the things which are God's." One would like to add: Give unto man things which are man's; give man his freedom and personality, his rights and religion.
Pope Pius XIISport, properly directed, develops character, makes a man courageous, a generous loser, and a gracious victor; it refines the senses, gives intellectual penetration, and steels the will to endurance.
