St. Ignatius Loyola suggests that in any exchange, “it is necessary to suppose that every good Christian is more ready to put a good interpretation on another’s statement than to condemn it as false.” To this call for charity, St. Ignatius added that if correction is necessary, it ought to be delivered with respect and kindness. Those qualities of respect and kindness have at times been hard to find in many of the heated arguments in which American Catholics have found themselves embroiled over the past 12 tumultuous months.

Can a Catholic in good conscience vote for Barack Obama? For John McCain? May pro-choice politicians be given Communion? Should the legal fight to overturn Roe v. Wade bear the full weight of Catholic political energy; or are there other, more effective strategies for combating the culture of death? Should the University of Notre Dame award an honorary degree to President Obama, or even invite him at all? Should there be more frequent celebrations of the liturgy in Latin; and if so, what version of the Mass texts should be used? Issues like these have always sparked much discussion in the Catholic community, but they are now often dominated by a tone that is decidedly dangerous—harsh and often lacking in respect or courtesy.

This rhetoric has threatened the credibility of the church, as the Catholic tradition of trust and toleration has been de-emphasized. Even a few bishops have made statements like “We are at war” and “Tolerance is not a Christian virtue,” suggesting that any notion of the common good has given way to a sharply defined “us versus them” mentality. Such rhetoric also subtly undermines the Catholic principle of subsidiarity first put forth by Pope Pius XI in Quadragesimo Anno, according to which a pluralistic social structure allows and encourages constructive input from a variety of groups on the grass-roots level.

This polarization must stop; otherwise our identity as a faith community will be torn asunder and Catholicism will cease to be an elevating force for change. How can we decrease the polarization? A vital first step is to seek out our common ground in the major civic areas where almost all Catholics agree: religious liberty; the sacredness of all human life; the goal of reducing and eventually eliminating abortion; support for social programs that provide a safety net for the poor; the elimination of segregation, racism and discrimination; and respect for differing religious and social traditions and diverse cultures. Few are the Catholics who do not share these principles, which provide a ready-made common ground.
