Vermont Senator Bernie Sanders, currently running for the Democratic Party’s nomination for president, had this to say today:

I am honored to be with you today and was pleased to receive your invitation to speak to this conference of The Pontifical Academy of Social Sciences. Today we celebrate the encyclical Centesimus Annus and reflect on its meaning for our world a quarter-century after it was presented by Pope John Paul II. With the fall of Communism, Pope John Paul II gave a clarion call for human freedom in its truest sense: freedom that defends the dignity of every person and that is always oriented towards the common good. 

The Church’s social teachings, stretching back to the first modern encyclical about the industrial economy, Rerum Novarum in 1891, to Centesimus Annus, to Pope Francis’s inspiring encyclical Laudato Si’ this past year, have grappled with the challenges of the market economy. There are few places in modern thought that rival the depth and insight of the Church’s moral teachings on the market economy.

(Emphasis supplied.) He went on to observe:

The essential wisdom of Centesimus Annus is this: A market economy is beneficial for productivity and economic freedom. But if we let the quest for profits dominate society; if workers become disposable cogs of the financial system; if vast inequalities of power and wealth lead to marginalization of the poor and the powerless; then the common good is squandered and the market economy fails us. Pope John Paul II puts it this way: profit that is the result of “illicit exploitation, speculation, or the breaking of solidarity among working people . . . has not justification, and represents an abuse in the sight of God and man.” (Para43).

Sanders was at the Vatican, you may remember, for a conference marking the 25th anniversary of Centesimus annus, hosted by the Pontifical Academy for Social Sciences. There was some controversy about Sanders’s visit to Rome, since the invitation, made at the behest of Bishop Marcelo Sanchez Sorondo, though that’s not really the interesting part of the story. The interesting part of the story—at least for us—is that an American presidential candidate traveled to the Vatican to discuss Centesimus annus, Rerum novarum, and Catholic social teaching more generally.
