There can be little doubt that an American papacy would result in a surge of energy for American Catholicism. Many local parishes would be filled for at least a few Sundays, as long-absent nominal Catholics return to the pews to participate in the victory celebration. Bill Donohue, the always camera-ready Catholic League president, would be booked solid for awhile, as news anchors wait in line for his insight and analysis. And this surge in American Catholicism would most likely result in a surge in church revenue, as the relatively wealthy American flock, appreciating its newfound connection to Rome, opens its checkbooks more generously.
The real question, however, is whether the energy would last, and whether an American pontiff would have a long-term impact on American society. Would Catholic theology suddenly be seen as more relevant in the lives of America’s Catholics, many of whom haven't practiced in years? Would the church as an institution find renewed legitimacy in the social/political arena?
