"At the heart of every culture, whether perceived or not, is a consensus about the nature of reality and the moral good, and thus about the conditions for human flourishing. In America, that consensus, as enshrined in your nation's founding documents, was grounded in a worldview shaped not only by faith but a commitment to certain ethical principles deriving from nature and nature's God. Today that consensus has eroded significantly in the face of powerful new cultural currents which are not only directly opposed to core moral teachings of the Judeo-Christian tradition, but increasingly hostile to Christianity as such." ~ Pope Benedict XVI to American Bishops, Jan 19, 2012
