Earlier this week, two prominent Catholic political bloggers, Elizabeth Stoker Bruenig and Pascal-Emmanuel Gobry (better known as Pegobry, or just PEG), engaged in a short but sharp exchange on the subject of property rights (see here, here, here, and here). There is not space here for a full discussion (see a longer version of this post here if you are interested in more), but I will seek to add some insight from Thomas Aquinas, who has perhaps done more than anyone to inform the Catholic Church’s reflection on these issues.
