“Whether it is popularly emphasized much or not, Catholic teaching in the famous encyclical Rerum Novarum by Pope Leo XIII tracks Thomas Aquinas’s quote above very closely: “Private ownership, as we have seen, is the natural right of man, and to exercise that right, especially as members of society, is not only lawful, but absolutely necessary” (22). Immediately after this passage in Rerum, the famous encyclical repeats Thomas’s above words. Taken together, all this underscores the Catholic call to public aid, not by heavy taxation but by private charity instead. The same paragraph in Rerum Novarum refines this concept even further: “Whoever has received from the divine bounty a large share of temporal blessings, whether they be external and material, or gifts of the mind [which cannot be taxed!], 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.”
