Pope Francis on Saturday warned that the “easy answers” of populism and authoritarianism are threatening democracy in Europe and called for fresh dedication to promoting the common good rather than narrow, nationalist interests.

Arriving in Greece, the birthplace of democracy, Francis used a speech to Greek political and cultural leaders to warn Europe at large about the threats facing the continent. He said only robust multilateralism can address the pressing issues of the day, from protecting the environment to fighting the pandemic and poverty.

“Politics needs this, in order to put common needs ahead of private interests,” Francis said. “Yet we cannot avoid noting with concern how today, and not only in Europe, we are witnessing a retreat from democracy.”

Francis, who lived through Argentina’s populist Peronist era as well as its military dictatorship, has frequently warned about the threat of authoritarianism and populism and the danger it poses to the European Union and democracy itself.

He didn’t name any specific countries or leaders during his speech. The EU, however, is locked in a feud with members Poland and Hungary over rule-of-law issues, with Warsaw insisting that Polish law takes precedence over EU policies and regulations.

Coincidentally, on the same day Francis warned about the populist threat to Europe, right-wing populist leaders met in Warsaw and declared they will work more closely together to defend their sovereignty at the European Parliament.

Outside the bloc, populist leaders in Brazil and the administration of former U.S. President Donald Trump pressed nationalist policies on the environment that contrasted sharply with Francis’ call to care for “our common home.”

Opening the second leg of his five-day trip to Cyprus and Greece, Francis recalled that it was in Greece, according to Aristotle, that man became conscious of being a “political animal” and a member of a community of fellow citizens.

“Here, democracy was born,” Francis told Greek President Katerina Sakellaropoulou. “That cradle, thousands of years later, was to become a house, a great house of democratic peoples. I am speaking of the European Union and the dream of peace and fraternity that it represents for so many peoples.”

That dream is at risk amid the economic upheaval and other disruptions of the pandemic that can breed nationalist sentiments and make authoritarianism seem “compelling and populism’s easy answers appear attractive,” Francis said.

“The remedy is not to be found in an obsessive quest for popularity, in a thirst for visibility, in a flurry of unrealistic promises … but in good politics,” he said.

Francis praised the “necessary vaccination campaign” promoted by governments to tame the coronavirus. He referenced another Greek doctor-philosopher — Hippocrates — in response to vaccine skeptics and virus deniers, who count many religious conservatives among them. Francis cited the Hippocratic oath to not only do what is best for the sick, but to “abstain from whatever is harmful and offensive to others,” especially the elderly.

Greece’s president echoed the sentiment. “The virus spreads and mutates, helped by the irrational denial of reality and inequalities in our societies,” Sakellaropoulou said.

Greece is grappling with its highest level of coronavirus infections since the start of the pandemic, with deaths approaching record levels. A quarter of the country’s adults remain unvaccinated, and Parliament recently approved a vaccine mandate for people over age 60.
