The debate over the application of the core teachings of the Christian faith began when Jesus was presented with a Roman coin containing Caesar's image. In that moment, the Lord drew both a limitation to the legitimate power of the state, and a distinction between it and the supreme authority of Almighty God. What would unfold over the years following was a highly balanced and well thought-out hierarchy of values rooted in a core understanding of the dignity of the human person. Yet it was not so abstract a set of principles as to be incapable of providing guidance for concrete policy mendations that nonetheless do not collapse dogmatic and unchangeable doctrine into the dynamic stuff of politics and policies.

Some mentators reject this point, offering in defense a quotation from Caritas in Veritate: "Clarity is not served by certain abstract subdivisions of the Church's social doctrine, which apply categories to Papal social teaching that are extraneous to it … There is a single teaching, consistent and at the same time, ever new."

Benedict's point here is that the Church's teaching in the moral realm is one consistent body of thought. It is not a hodgepodge of policy concerns, among which Catholics may pick and choose along the lines of the fashionable Cafeteria Catholicism. The Church's solicitude for the poor, the marginalized, the unborn, and the elderly is all of a piece. In that sense, the critique is correct: A Catholic cannot subordinate "justice issues" to "life issues"; he must embrace the Church's teaching as a whole, because life issues are justice issues.

When es to doing good, which is what addressing poverty entails, the Church does not stipulate exactly how such good is to be done. Helping the poor requires a different sort of moral analysis — not because I (or the Church's teaching) am "dualist," as some critics suggest, nor because assisting the poor is "less important" than protecting the unborn, but because the two issues possess different characteristics and therefore require different sorts of moral analysis.

It is possible to argue that cutting welfare programs is consistent with Catholic social teaching, because we may choose from the various options available to us to do good by evaluating them in the hierarchy of goods. It will not do to fling citations of social encyclicals at each other on this point. Certainly there are passages that could be found to support increased government activity in the economy and provision of social services — when necessary to serve mon good.

At the root of the incredulity and exasperation of some Catholics who mix fair arguments with vitriol is an incapacity to recognize that we really believe that many government programs aggravate rather than ameliorate poverty and other social ills. Rather than debating the prudence of the policies at hand, detractors resort to ad hominem attacks and pronounce anathemas selectively. Yet there is by this time a vast literature on the damage wrought by the war on poverty and its failure to achieve its goals. Such critics can continue to believe that shoveling government money into welfare programs discharges Catholic social teaching's obligation to assist the poor if they wish, but their inability to see other views as reasonable, at least, is distressingly myopic.

A Catholic may not disregard the Church's teaching to assist the poor and vulnerable; to do so would be to neglect the words and example of Christ Himself. It would be, in effect, to deny the Faith. But on the question of how best to fulfill that obligation, Catholics will indeed disagree, and the Church does not teach that it must be otherwise. The same kind of latitude is not permitted when es to legal protection of the unborn. I do not believe that this is "my view" of the matter; it is the mind of the Church, to which I hope my own mind is conformed.
