This afternoon, Denver Archbishop, Charles J. Chaput will respond to questions and discuss his recent book, "Render Unto Caesar: Serving the Nation by Living Our Catholic Beliefs in Political Life." In the book, the prelate encourages Catholics to participate in public life, where faith and politics intersect.

In "Render Unto Caesar," published by Doubleday in August 2008, the archbishop urges Catholics to strengthen their voice on issues such as abortion, the death penalty, immigration, poverty, and other social justice issues.

During the internet discussion session, Archbishop Chaput will be joined by Knights of Columbus Supreme Knight Carl Anderson and will answer questions about his book live at 5 p.m. EDT.
