Even apart from policy questions, there’s much to learn about Benedict XVI’s papacy from Deus Caritas Est.
First, he will not, as some feared, lead the Catholic church to collapse in on itself and become preoccupied with its own internal business. One can hardly imagine a theme of more universal human concern than love.
Second, while he possesses vast erudition (in the first 20 pages of Deus Caritas Est, he manages to cite Nietzsche, Descartes, and Plato), Benedict expresses himself as a pastor. He treats a core theme of Christian faith, and for the most part uses terms that don’t require a license in systematic theology to grasp. While history will remember John Paul II as a great evangelist, Benedict XVI may go down as the most classic example of a "teaching pope" in modern times.
Third, for all the talk about Benedict as an Augustinian pessimist, he actually believes there are still people in the world who can be influenced by unadorned argument, shorn of theatricality or grand symbolism. In its own way, it’s a remarkably optimistic stance.
Fourth, Benedict grasps the old bit of wisdom about governing the Catholic church expressed by John XXIII, who once said, "I have to be pope both of those with their foot on the gas, and those with their foot on the brake." Deus Caritas Est reflects an obvious concern for balance. He warns Catholic charitable groups they must not forget about Christ, yet understands there are times when this faith must go unspoken, so charity workers don’t give the appearance of "proselytism"; he stresses the "vertical dimension" of prayer and worship, yet also writes that "a Eucharist which does not pass over into the concrete practice of love is intrinsically fragmented."
