The American republic depends upon the answers to two questions. By what ultimate truths ought we to live? And how should these be related to public life? The first question is personal, but has a public dimension because of the connection between beliefs and public virtue. The American answer to the first question is that the government is excluded from giving an answer. The second question, however, is thoroughly public in character, and a public answer is appropriate and necessary to the well-being of this society.
This second question was central to the idea of the First Amendment. The Religious Liberty provisions are not "articles of faith" concerned with the substance of particular doctrines or of policy issues. They are "articles of peace" concerned with the constitutional constraints and the shared prior understanding within which the American people can engage their differences in a civil manner and thus provide for both religious liberty and stable public government.
Conflicts over the relationship between deeply held beliefs and public policy will remain a continuing feature of democratic life. They do not discredit the First Amendment, but confirm its wisdom and point to the need to distinguish the Religious Liberty clauses from the particular controversies they address. The clauses can never be divorced from the controversies they address, but should always be held distinct. In the public discussion, an open commitment to the constraints and standards of the clauses should precede and accompany debate over the controversies.
Such a position betrays a failure of civil respect for the convictions of others. It also underestimates the degree to which the Framers relied on the American people's religious convictions to be what Tocqueville described as "the first of their political institutions." In America, this crucial public role has been played by diverse beliefs, not so much despite disestablishment as because of disestablishment.
The Founders knew well that the republic they established represented an audacious gamble against long historical odds. This form of government depends upon ultimate beliefs, for otherwise we have no right to the rights by which it thrives, yet rejects any official formulation of them. The republic will therefore always remain an "undecided experiment" that stands or falls by the dynamism of its non-established faiths.
The lesser argument is one of expediency and is based on the ironic fact that each side has become the best argument for the other. One side's excesses have become the other side's arguments; one side's extremists the other side's recruiters. The danger is that, as the ideological warfare becomes self-perpetuating, more serious issues and broader national interests will be forgotten and the bitterness deepened.
The more important argument is one of principle and is based on the fact that the several sides have pursued their objectives in ways which contradict their own best ideals. Too often, for example, religious believers have been uncharitable, liberals have been illiberal, conservatives have been insensitive to tradition, champions of tolerance have been intolerant, defenders of free speech have been censorious, and citizens of a republic based on democratic accommodation have succumbed to a habit of relentless confrontation.
The First Amendment has contributed to avoiding both these perils, but this happy experience is no cause for complacency. Though the United States has escaped the worst excesses experienced elsewhere in the world, the republic has shown two distinct tendencies of its own, one in the past and one today.
In earlier times, though lasting well into the twentieth century, there was a de facto semi-establishment of one religion in the United States: a generalized Protestantism given dominant status in national institutions, especially in the public schools. This development was largely approved by Protestants, but widely opposed by non-Protestants, including Catholics and Jews.
In more recent times, and partly in reaction, constitutional jurisprudence has tended, in the view of many, to move toward the de facto semi-establishment of a wholly secular understanding of the origin, nature and destiny of humankind and of the American nation. During this period, the exclusion of teaching about the role of religion in society, based partly upon a misunderstanding of First Amendment decisions, has ironically resulted in giving a dominant status to such wholly secular understandings in many national institutions. Many secularists appear as unconcerned over the consequences of this development as were Protestants unconcerned about their de facto establishment earlier.
Such de facto establishments, though seldom extreme, usually benign and often unwitting, are the source of grievances and fears among the several parties in current controversies. Together with the encroachments of the expanding modern state, such de facto establishments, as much as any official establishment, are likely to remain a threat to freedom and justice for all.
Justifiable fears are raised by those who advocate theocracy or the coercive power of law to establish a "Christian America." While this advocacy is and should be legally protected, such proposals contradict freedom of conscience and the genius of the Religious Liberty provisions.
At the same time there are others who raise justifiable fears of an unwarranted exclusion of religion from public life. The assertion of moral judgments as though they were morally neutral, and interpretations of the "wall of separation" that would exclude religious expression and argument from public life, also contradict freedom of conscience and the genius of the provisions.
Two important conclusions follow from a reappraisal of the present controversies over religion in public life. First, the process of adjustment and readjustment to the constraints and standards of the Religious Liberty provisions is an ongoing requirement of American democracy. The Constitution is not a self-interpreting, self-executing document; and the prescriptions of the Religious Liberty provisions cannot by themselves resolve the myriad confusions and ambiguities surrounding the right ordering of the relationship between religion and government in a free society. The Framers clearly understood that the Religious Liberty provisions provide the legal construct for what must be an ongoing process of adjustment and mutual give-and-take in a democracy.
We are keenly aware that, especially over state-supported education, we as a people must continue to wrestle with the complex connections between religion and the transmission of moral values in a pluralistic society. Thus, we cannot have, and should not seek, a definitive, once for all solution to the questions that will continue to surround the Religious Liberty provisions.
Second, the need for such a readjustment today can best be addressed by remembering that the two clauses are essentially one provision for preserving religious liberty. Both parts, No establishment and Free exercise, are to be comprehensively understood as being in the service of religious liberty as a positive good. At the heart of the Establishment clause is the prohibition of state sponsorship of religion and at the heart of Free Exercise clause is the prohibition of state interference with religious liberty.
No sponsorship means that the state must leave to the free citizenry the public expression of ultimate beliefs, religious or otherwise, providing only that no expression is excluded from, and none governmentally favored, in the continuing democratic discourse.
No interference means the assurance of voluntary religious expression free from governmental intervention. This includes placing religious expression on an equal footing with all other forms of expression in genuinely public forums.
No sponsorship and no interference together mean fair opportunity. That is to say, all faiths are free to enter vigorously into public life and to exercise such influence as their followers and ideas engender. Such democratic exercise of influence is in the best tradition of American voluntarism and is not an unwarranted "imposition" or "establishment."
