The title of the book itself gives a hint to its contents: "Render Unto Caesar. Serving the Nation by Living Our Catholic Beliefs in Political Life." It is right to give Caesar what belongs to him. But one serves the nation by living out one's own Catholic faith in political life.
Chaput moves decisively against the prevailing cultural tide in the media, in the universities, among political activists, a tide that wants to thrust the faith from the public stage.
But he is also issuing a challenge to the American Catholic community. There are 69 million Catholics in the United States, one fourth of the population. More than 150 congressmen say they are Catholic. In the Senate, the Catholics are one out of four. They are the majority on the Supreme Court. But, the author of the book asks, what difference do they make?
Among the American bishops, Chaput is one of the most decisive in taking clear positions on abortion, the death penalty, immigration. In the controversy over giving communion to "pro-choice" Catholic politicians, he maintains that those who ignore the Church's teaching on abortion are no longer in communion with the faith. They separate themselves from the community of the faithful. And therefore, if they take Eucharistic communion, they commit an act of dishonesty.
