"The very future of the world is at stake..."--Pope Benedict XVI

Pope Benedict XVI cites America as a model for people living in harmony:

...Alexis de Tocqueville, in his day, observed that democracy in America had become possible and had worked because there existed a fundamental moral consensus which, transcending individual denominations, united everyone. Only if there is such a consensus on the essentials can constitutions and law function. This fundamental consensus derived from the Christian heritage is at risk wherever its place, the place of moral reasoning, is taken by the purely instrumental rationality of which I spoke earlier. In reality, this makes reason blind to what is essential. To resist this eclipse of reason and to preserve its capacity for seeing the essential, for seeing God and man, for seeing what is good and what is true, is the common interest that must unite all people of good will. The very future of the world is at stake...
