The argument for a Christcentric blueprint?

In a deeply polarized and pluralistic America, can a singular, Christcentric framework truly offer a comprehensive blueprint for national purpose—or does relying on a specific religious paradigm inherently deepen our modern divisions and exclude millions of citizens from the shared future of the United States? 

When you wonder about the mystery of yourself, look to Christ, who gives you the meaning of life. When you wonder what it means to be a mature person, look to Christ, who is the fullness of humanity. And when you wonder about your role in the future of the world and of the United States, look to Christ.
