May 15, 2016 marked the 125th Anniversary of Rerum Novarum, widely considered the foundation of modern Catholic social teaching. In this 1891 Encyclical, Pope Leo XIII examined the industrial revolution in light of Christian teaching on justice. Finding that the traditional economy of small property owners (farmers and artisans) was giving way to an economy dominated by a few property owners and a large working class, the Holy Father criticized the laissez-faire economy and gave a strong endorsement to trade unions. But where contemporary socialists anticipated ever-increasing class struggle, Leo believed that labor unions could play a positive role – like their medieval predecessors, the guilds, they could defend the economic interests of the workers, advance the quality of their trade, and provide an opportunity for labor and management to adjust disputes in the common interest.
