While scholars have recognized a resurgence of religion, their focus mainly has been on religion's more violent aspects, overlooking its peaceful capacities and effects. This oversight is due in part to the lack of theoretical rigor when it comes to the study of politics and religion. Using the Catholic Church's opposition to the United States’ 2003 war in Iraq, this article highlights the political significance of religion's moral, symbolic voice, which is as important as the hard power that has traditionally dominated international relations. The post-Vatican II Catholic Church's modern articulation of human dignity and interpretation of just war theory challenges both scholars and policymakers to utilize the peaceful, diplomatic methods that international relations theory and practitioners have made available. Religion's role in politics, therefore, can be one that is supportive of modern political societies and it need not be violent.
