119 Our predecessors have insisted time and again on the social function inherent in the right of private ownership, for it cannot be denied that in the plan of the Creator all of this world's goods are primarily intended for the worthy support of the entire human race. Hence, as Leo XIII so wisely taught in Rerum Novarum : "whoever has received from the divine bounty a large share of temporal blessings, whether they be external and corporeal, or gifts of the mind, has received them for the purpose of using them for the perfecting of his own nature, and, at the same time, that he may employ them, as the steward of God's Providence, for the benefit of others. 'He that hath a talent,' says St. Gregory the Great, '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 thereof with his neighbor'." (36)
