Robert Bellah said no. American civil religion involves a god different from the Christian one:
What we have, then, from the earliest years of the republic is a collection of beliefs, symbols, and rituals with respect to sacred things and institutionalized in a collectivity. This religion-there seems no other word for it-while not antithetical to and indeed sharing much in common with Christianity, was neither sectarian nor in any specific sense Christian. At a time when the society was overwhelmingly Christian, it seems unlikely that this lack of Christian reference was meant to spare the feelings of the tiny non-Christian minority. Rather, the civil religion expressed what those who set the precedents felt was appropriate under the circumstances. It reflected their private as well as public views. Nor was the civil religion simply “religion in general.” While generality was undoubtedly seen as a virtue by some, as in the quotation from Franklin above, the civil religion was specific enough when it came to the topic of America. Precisely because of this specificity, the civil religion was saved from empty formalism and served as a genuine vehicle of national religious self-understanding.
But American civil religion may surpass Christianity in wisdom and significance:
I would argue that the civil religion at its best is a genuine apprehension of universal and transcendent religious reality as seen in or, one could almost say, as revealed through the experience of the American people. Like all religions, it has suffered various deformations and demonic distortions. At its best, it has neither been so general that it has lacked incisive relevance to the American scene nor so particular that it has placed American society above universal human values. I am not at all convinced that the leaders of the churches have consistently represented a higher level of religious insight than the spokesmen of the civil religion. Reinhold Niebuhr has this to say of Lincoln, who never joined a church and who certainly represents civil religion at its best:
An analysis of the religion of Abraham Lincoln in the context of the traditional religion of his time and place and of its polemical use on the slavery issue, which corrupted religious life in the days before and during the Civil War, must lead to the conclusion that Lincoln’s religious convictions were superior in depth and purity to those, not only of the political leaders of his day, but of the religious leaders of the era.[xii]
Perhaps the real animus of the religious critics has been not so much against the civil religion in itself but against its pervasive and dominating influence within the sphere of church religion.
We know we’re not supposed to put our trust in princes. But what about the princes’ gods?
