America's Biblical tradition is an important one to preserve, but one must keep in mind the great limitations of arguing from the standpoint of revealed truth. The cultural elite remains in open rebellion against religious authority and belief because they are driven by a radical desire to build a society in which man is free to escape any limits on human will and expression. It does very little good to battle these cultural elites on terms that only reinforce their prejudices and confirms their stereotypes. The better approach is to simply attempt to force them to confront the consequences of their own philosophy. It is they, not you, who should be the issue.
Language makes a big, big difference here.
The answer lies in discovering the profound truth of the founding fathers embodied particularly in the Declaration of Independence. The framing produced a Puritan-Lockean synthesis which adopted neither secularism nor sectarianism, but settled for a basic acceptance of the higher law rooted in God, to whom we are all ultimately accountable. Many around us share our concern over the collapse of our legal structures due to a political and legal theory that locates morality in nothing higher than majority rule. Finally, we must be reminded of Richard John Neuhaus's advice for operating in the public square. There may be a greater hunger today for our spiritual answers than for our political proposals.
