Frederick Clarkson, a senior fellow at Political Research Associates (PRA), has written an important, insightful, and almost certainly prophetic look at the strengthening alliance between Roman Catholic and Protestant elements of the religious right.
As PRA summarizes:
Despite recent losses in the culture war, the Christian Right is forging a path forward by rallying around a few key issues: antichoice, opposition to marriage equality, and the defense of “religious liberty.” These themes—set forth in the influential Manhattan Declaration in 2009—have proved powerful enough to unify conservative Catholics and Protestants against their common enemies.
From Clarkson's article:
Given the Christian Right’s recent defeats in the realm of marriage equality, it might seem that its power is diminishing and that the so-called culture wars are receding. But “We Stand in Solidarity” is one of many indications that its resolve has deepened rather than dissipated in the face of recent political setbacks. This dynamic, multifaceted movement—one of the most powerful in U.S. history—aims to become a renewed, vigorous force in American public life, and it continues to evolve even while maintaining its views on core issues.
Notably, the movement is being shaped and sustained by a political alliance between evangelicals and the leadership of the Roman Catholic Church. Though it was unthinkable as recently as a decade ago, this developing evangelical-Catholic alliance is key to understanding the Christian Right’s plan for regrouping in the near term—and ultimately reclaiming the future.
