Some of this challenge is tonal. A revolutionary populism has seldom been the Catholic style -- especially since Catholics have often been the victims of such populism in American history. Catholicism asserts the value and dignity of duly constituted authority, both religious and political, which cannot be dismissed as "elites." Further, in a direct assault on the spirit of the age, it teaches that genuine freedom is found in submission to just authority. The alternative is the "freedom" of a fish liberated from the sea. Neither radical individualism nor disdain for government is an option.
But the tension is also substantive. Catholic social teaching is simply not libertarian. Neither, of course, are most conservatives. But where Republicans veer toward libertarianism, they will run smack into the bishops.
The Catholic tradition asserts the necessity of limited government. The establishment of justice and acts of compassion should be done at the lowest, most human levels of society, instead of by distant, centralized bureaus -- a perspective fully consistent with the designs of America's founders. But gaps in the justice and compassion of a society require government intervention to secure the common good, which is not common until it includes the poor, the immigrant, the sick, the disabled, the unborn. Catholic teaching elevates the primary importance of families, charities and strong communities -- while rejecting the simplistic notion that such institutions render government unnecessary. In determining the proper balance between civil society and government, there is much room for political debate. But the search for that balance is a source of sanity in our political life, involving the rejection of both collectivist and libertarian utopias.
So how will Catholic Republicans respond to these arguments? The U.S. Conference of Catholic Bishops, after all, has no canonical standing, just a moral authority that has been recently diminished by scandal.
But there will likely come a point when red lines get crossed and Catholic and other religious leaders declare: Contempt for immigrants, even illegal immigrants, is not a moral option. Or, cutting AIDS and malaria funding violates pro-life principles. Or, health care repeal without a serious alternative is not responsible.
At that moment, one hopes, the faith of politicians has sunk deeper than the skin -- and that they will be less nasty than they otherwise would have been.
