Mater et Magistra §43

⁴³ Concerning the use of material goods, Our Predecessor declared that the right of every man to use these for his own sustenance is prior to every other economic right, even that of private property. The right to the private possession of material goods is admittedly a natural one; nevertheless, in the objective order established by God, the right to property cannot stand in the way of the axiomatic principle that "the goods which were created by God for all men should flow to all alike, according to the principles of justice and charity" (20)
