In a fascinating essay at Patheos, Dean Curry describes Malcolm Magee's argument in What the World Should Be that President Woodrow Wilson's foreign policy was decisively shaped by his Presbyterian Reformed theology.

It is well known that Woodrow Wilson was a foreign policy idealist and that his approach to it was moralistic. After all, it was Wilson who famously promised that America's participation in World War I would not be about selfish national interest—or realpolitik -- but about the altruism of making the world "safe for democracy." What is not well known about Wilson, and what Magee explains in fascinating detail, is how Wilson's personal and political worldview was profoundly shaped by Reformed Protestant theology. Challenging the prevailing historiography of Wilson that has all but ignored Wilson's theology, it is Magee's thesis that Wilson was a "Presbyterian in politics, a twentieth century John Knox, a Christian statesman whose overriding motivation was his determination to do God's work in a fallen world."

Curry goes on to describe Wilson's relationship with his father, a very prominent Southern Presbyterian pastor, and the influence on Wilson's thinking of Princeton theologians like Charles Hodge, A. A. Hodge, and Benjamin B. Warfield. Curry also outlines Wilson's friendship with J. Gresham Machen, as well as similarities between Wilson's understanding of the relation between Reformed faith and politics, and that of Abraham Kuyper.

Though Wilson was not drawn to fundamentalism, his theological ideas had much in common with the transformational, neo-Calvinism of Abraham Kuyper. Kuyper delivered his famous world-and-life-view-focused "Stone Lectures" at Princeton in 1898 where Woodrow Wilson was now a professor of jurisprudence and political economy. While Magee writes that there is no record of Wilson and Kuyper meeting, he observes that like Kuyper, "the distinction between secular and sacred . . . simply did not exist in Wilson's mind."

Curry's essay is excellent and it is well worth your while to read the whole thing. The evidence that President Wilson was a devout Calvinist Presbyterian (though not always an entirely orthodox one, by his own admission) is decisive and indisputable.

That said, I want to make a few clarifying points about Wilson's relation to Machen and Kuyper, as well as about Curry's discussion of Calvin's influence on Wilson. First, Magee does not describe any relationship between Wilson and Machen in his book. In fact, he does not mention Machen at all. And as anyone familiar with Darryl Hart's excellent work on Machen is aware, Machen's view of the connection between Christianity and politics was profoundly different from that of Wilson. Machen, says Hart, sought to distinguish the gospel from theories of social or political transformation. It is also worth noting that, in his biography of Machen, Hart gives no indication that the relationship between the two was anything more than one of general acquaintance.
