Stanley Hauerwas
— author of Resident Aliens and Hannah’s Child
"New Testament scholar David Crump has the courage to write a book in Christian ethics that explores how Christians must learn how to negotiate a world in which they are no longer in control. One of the delights of this book is Crump’s careful and constructive use of the New Testament to help us see what it means for Christians to recover the radical character of an ethic of discipleship."

William T. Cavanaugh
— author of Being Consumed and Migrations of the Holy
"This book meets two needs. The first is for a biblically based analysis of the ethical issues of our day aimed at an educated lay audience. The second is for a book by an evangelical Christian that challenges evangelicals to take Jesus seriously in living out their citizenship. In forthright language and with the aid of real-life examples, Crump calls Christians to reject the idolatrous political and economic allegiances that divide the church."

Ronald J. Sider
— author of Rich Christians in an Age of Hunger and The Scandal of the Evangelical Conscience
"A powerful, passionate plea to American Christians to follow Jesus rather than conform to a broken culture. . . . Biblical, urgent, provocative. A must-read."

Gregory A. Boyd
— author of The Myth of a Christian Nation and Letters from a Skeptic
"Well-written, insightful, and compellingly argued. Crump exposes the frightful degree to which the church in America has been co-opted by the secular ideals and agendas of our country. I Pledge Allegiance is a much-needed clarion call for the American church to turn from its divided loyalties and once again embrace the singular devotion to Christ and his kingdom that lies at the heart of the gospel."
