If Rick Santorum is so staunch a Catholic, why does he often sound such a Protestant, not to say puritanical, note? His remarks about how President Obama’s world view is just “some phony theology” have received a lot of attention but too little examination. It turned out that Santorum was talking, in general terms, about “radical environmentalists,” and using environmentalism as a synecdoche for everything he abominates in secular progressive politics. “This idea that man is here to serve the earth as opposed to husband its resources and be good stewards of the earth” is, he maintained on CBS’s “Face the Nation,” “a phony ideal. I don’t believe that’s what we’re here to do. That man is here to use the resources and use them wisely, to care for the earth, to be a steward of the earth. But we’re not here to serve the earth. The earth is not the objective. Man is the objective, and I think a lot of radical environmentalists have it upside-down.” That kind of ideology, he complained, “elevates the earth above man.”

Put aside theology for a moment. Just intellectually, there are many peculiarities here. According to Santorum, environmentalists and leftists believe in serving the earth, while proper Christians “should have dominion over it, and should be good stewards of it.” The distinction Santorum is working here is between a very narrow definition of service as idol-worship (in which the earth becomes our fetish), and stewardship as responsible husbandry. He means, in effect: “Secularists have made a false idol of the earth, whereas God is the only true object of worship.” (And note that he can make this point only by taking the cherished Christian term “service” and casting secular dirt on it.) There may indeed be radical outliers in contemporary ecology for whom the survival of man is subservient to the survival of the world. But for most people anxious about the fate of the environment, service and stewardship would seem to go together. Note, too, that all this talk about making man the objective sounds quite like the supposed heresy of rational humanism. If you took away the theological context of Santorum’s screed, you would have a program for secular politics: Since we are here to serve man, then we should start getting busy with projects of political salvation, like universal health care, environmental protection, the alleviation of poverty, and so on.

Of course, it is not possible to put theology aside. I know the theological weight of that word, “steward.” When I was a boy, my mother, in the grip of her Scottish evangelical Protestantism, used to chide me for my untidy bedroom, adding that, as a Christian, it was an example of “poor stewardship.” Everything is the Lord’s, and our brief role on earth is merely to husband it in a right way, a way that gives the Lord His due. Christianity, with its emphasis on the afterlife, has always had a tendency to derogate earthly living as a kind of spectral vanity. And the early Christians, who like St. Paul were convinced that Jesus’s return, and thus the end of the known world, was imminent, had particular reason to treat life as a ghostly antechamber to the joys of eternity. There is a sharp difference between the other-worldly asceticism of Christianity and the life-filled practicality of Biblical Judaism, which has a vague or non-existent notion of the afterlife. It was this asceticism, among other irritants, that caused Nietzsche to accuse Christianity of turning life upside-down—of privileging sickness over health, weakness over strength, the life to come over the life here. “Christianity was, from the beginning, essentially and fundamentally, nausea and disgust with life, merely concealed behind, masked by, dressed up as, faith in ‘another’ or ‘better’ life,” he wrote in “The Birth of Tragedy.” As the secularist might see it, Santorum is the one who has got things upside-down.

The curious aspect of this apocalyptic asceticism is that it is more obviously associated with Protestantism and Puritanism than with the Catholic Church. Growing up, I was always struck by the relatively relaxed worldliness of Catholics. Their priests were officially barred from sex, but they enjoyed good food and wine, told dirty jokes, lived in the world, and so on. Catholics seemed to lay the emphasis on forgiveness rather than Calvinist damnation; the whole delicious mystery of the confessional bespoke a customary accommodation with the temptations and consolations of secular life. Historically, Protestantism came about, in part, as a reaction to such Catholic relaxation. And a major theme of Protestantism—more sharply focussed through the lens of Puritanism—became the image of life as a kind of shadow of the true life above; of our time on earth as a pilgrimage toward the heavenly kingdom. It is there in the works of John Hooper (c. 1500-1555), considered the father of English Puritanism, when he writes that we must “see, know and understand the vanities of this world, the shortness and misery of this life, and the treasures of the life to come.” It is there in John Bunyan’s “The Pilgrim’s Progress,” and omni-present in Jonathan Edwards’s work, notably in “The Christian Pilgrim,” when he writes that the enjoyment of God is the only happiness with which our souls can be satisfied:

To go to heaven, fully to enjoy God, is infinitely better than the most pleasant accommodation here. Fathers and mothers, husbands and wives, or children, or the company of earthly friends are but shadows; but God is the substance.

Melville, brought up in the Dutch Reformed Calvinist faith, plays around with this kind of theology in “Moby-Dick,” when he has Captain Ahab claim that all visible objects are but “pasteboard masks.” Santorum may claim, as he did in 2008, that “mainline Protestantism in this country … is gone from the world of Christianity, as I see it,” but, with his attacks on “Satan” and “sensuality,” and his apocalyptic or even post-millennial Christianity, he often sounds like an eighteenth-century American Puritan.

Hence a particular impatience with the values of environmental conservation. For the apocalyptic Christian, sights set firmly on heavenly life, the earth might indeed be a finite and transitory thing, what William Blake wonderfully called a “mundane egg.” Man is what needs to be protected, because each of us is a soul, whose eternal fate is up for grabs.

So when Santorum says that we must be good stewards of the earth, there is religious zealotry behind the sweet words. He is proposing, in effect, that the earth is dispensable but that our souls are not; that we will all outlive the earth, whether in heaven or hell. The point is not that he is elevating man above the earth; it is that he is separating man and earth. If President Obama really does elevate earth over man (accepting Santorum’s absurd premise for a moment), then at least he believes in keeping man and earth together. Santorum’s brand of elevation involves severing man from man’s earthly existence, which is why it is coherent only within a theological eschatology (a theology of the last days). And he may well believe that man cannot actually destroy the earth through such violence as global warming, for the perfectly orthodox theological reason that the earth will come to an end (or be renewed) only when Christ comes again to judge the living and the dead. In other words, global warming can’t exist because it is not in God’s providential plan: the Lord will decide when the earth expires. This is Santorum’s “theology,” phony or otherwise.
