For much of American history, an impassable gulf seemed to separate Jews and Christians, keeping their respective peoples and cultures far apart. But in recent decades that has begun to change. The rise of a militant secularism, one equally hostile to Israel and to America’s Judeo-Christian values and institutions, has unexpectedly drawn Jews and Christians closer together. In the face of a common civilizational threat, the study of the two traditions’ joint contributions to the West has risen to the fore. Jewish Roots of American Liberty illustrates how the free institutions, principles, and liberties that we value so much in today’s America—including Christianity itself—are securely grounded in Jewish antecedents.
