If you read On the Square with any regularity (which I am sure you do) you are probably familiar with the thoughtful and instructive writings of Denver’s Bishop Charles Chaput. This past Tuesday saw the release of the Bishop’s new book, Render Unto Caesar, which tackles the ever-topical question of how Catholics are to exercise political agency, particularly in a pluralistic, liberal democratic state like the United States.  Fr. Robert Imbelli (an Associate Professor of Theology at Boston College) has written a thorough review of the book for L’Osservatore Romano. His verdict is wholly positive. He judges the book a signal contribution to a most important debate, and urges Catholics and non-Catholics, Americans and non-Americans, to carefully consider and discuss its arguments and analyses.
