During his recent trip to the United States, Pope Francis, truly a global icon since his unexpected election in 2013, was the subject of lavish veneration from American citizens, writers and politicians across political and religious backgrounds. Such universal praise is entirely sincere, and it offers hope of a genuine unity of human values beneath our many conflicts.  At the same time, such flattering words cannot hide a tragic irony—the actual contact of Catholic social justice teaching Pope Francis so vividly embodies dwells in a lonely desert on our national political landscape.

To be sure, faith will inevitably conflict with any ideology, which precisely gives it creative power. Coalition building will always make for uneasy political bedfellows. In a pluralistic society with separation of church and state, people of faith must primarily use the language of reason and philosophy, as opposed to theology, to make their public arguments. Nevertheless, the strict ideological litmus tests on both our Left and Right excommunicates Catholics and other people of faith following the path of Pope Francis, who desire to live out consistently rather than cherry pick their vision of social justice.

Pope Francis’ denunciation of the moral ambiguities and uneven costs of capitalism are not unique to his papacy, but his candor has sparked visceral outrage among American conservatives. Pundits from Rush Limbaugh to George Will accuse Francis of “Marxist”, “communist”, and “Peronist” leanings. The evasive reactions of Catholic Republican presidential candidates to Francis’ environment encyclical “Laudato Si’” reveal an unwillingness to even slightly rethink their party’s libertarian economic orthodoxies.

More thoughtful Catholic conservatives rightly note that the Vatican is not an infallible think tank, releasing policy statements binding on the faithful. And papal teaching indeed broadly endorses private property and the market economy as proven tools for advancing both individual freedom and the common good.

Nevertheless, there is a consistent history of leading Catholic conservative intellectuals in America downplaying or ignoring their Church’s political teachings when it challenges the party line. As war drums beat for Operation Iraqi Freedom in 2003, religious conservatives neglected John Paul II’s perceptive warning that the intervention would lead to utter catastrophe. When Benedict XVI called for a major restructuring of the global financial system, writer George Weigel claimed that crafty left-leaning Curia officials, not the pontiff, were responsible for such proposals. Such examples point to a failure of American conservatism to build a sincere, honest dialogue with Catholic reflections on economic issues.

But the American Left is certainly guilty too of groupthink and ideological exclusion. One of the great tragedies of recent politics is the near disappearance of visible pro-life Democrats, who saw opposition to abortion, war, poverty, and capital punishment as a united commitment to a “consistent ethic of life”, a favorite term of the Christian Left. Even after Roe v. Wade, leading Democrats, including Sargent Shriver, Ted Kennedy and Jesse Jackson, expressed this view, although many adjusted their positions as the party’s direction became more dogmatic. Today, although a Gallup study in 2011 found that one in three Democrats describe themselves as pro-life, less than three percent of Democrats in Congress share this position. Indeed, a pro-life Democrat would find progressive circles an uncomfortable home when their principled view is vilified as medieval, patriarchal or uncaring. A presidential frontrunner can give paid speeches for Goldman Sachs or cynically flip-flop on countless issues, but if an aspiring Democratic politician or thinker even remotely challenges the party consensus on abortion—anathema sit.

The great religious progressives of an earlier era, be it Martin Luther King Jr., Reinhold Niebuhr or Abraham Heschel, would likely be horrified at the militant, condescending secularism common in contemporary liberal thought on most cultural questions. Their postwar liberalism drew on historic, traditional understandings of human personhood and dignity. Today, we see a descent into a “dictatorship of relativism” warned of by Benedict XVI, where older and spiritual and moral wisdom is ignored, caricatured and demonized in the pursuit of frequently shallow, postmodern definitions of freedom.

Pope Francis’ warnings about modernity’s “throwaway culture”, “globalization of indifference” or “idolatry of money” should not be political footballs but invitations for deeper reflection by every worldview and every person. It is time that our public life creates the space for the social and ethical thought he offers to share itself freely, in its fullness rather than isolated fragments. Catholic social teaching will neither transform America into a socialist dystopia nor a repressive theocracy. Rather, its wisdom will contribute to a richer understanding of human dignity and the common good our country desperately needs. Pope Francis captured our hearts and minds last week. Let us not allow his journey to America to have ended in vain.
