what does rerum novarum teach about ownership and use of private property
Rerum novarum Although the Encyclical follows the lines of the traditional teaching concerning the rights and duties of property and the relations of employer and employee, it applies the old doctrines specifically to modern conditions.[12] Leo first quotes Thomas Aquinas in affirming that private property is a fundamental principle of natural law. He then quotes Gregory the Great regarding its proper use: ""He that hath a talent, let him see that he hide it not; he that hath abundance, let him quicken himself to mercy and generosity; he that hath art and skill, let him do his best to share the use and the utility hereof with his neighbor."[13] Liberalism also affirms the right to private property, but socialism and communism do not.
Beneficial owner Beneficial owner is a legal term where specific property rights ("use and title") in equity belong to a person even though legal title of the property belongs to another person. Black's Law Dictionary (2nd Pocket ed. 2001 pg. 508). This often relates where the legal title owner has implied trustee duties to the beneficial owner.
