I think the idea of "civil religion" is a contradiction in terms.

Religion is generally accepted to be based on belief in a supreme being or deity, which is worshiped, propitiated, or feared by adherents to that religion.

Government, on the other hand, is a civil authority, lacking deities, at least in the case of the United States, where state-sponsored religion is prohibited by our founding documents.

Religion is not just celebrations, ceremonies, and participation in activities. The reason for those things in religion centers around that deity or supreme being. All of them have, at their core, recognition, honoring, and praying to that deity.

Civil events are not about that. They are about a common social structure, regardless of belief in supernatural entities. I do not attend my city council meetings to worship anything at all. I attend to make my opinions known to my elected officials. I do not write letter sto my legislators, state and federal, with the intent of praying to any deity. Instead, I remind those legislators that I have opinions regarding laws they are considering.

I do not attend fourth of July celebrations or any other such patriotic assemblies to worship at any altar. I attend them because I am part of this society, which supposedly welcomes people of all faiths and of no faith at all.

Robert Bellah, in his writings, attempted to define what a "civil religion" was, but failed, because there is no supreme being necessarily involved in systems of government, especially here in the United States, where such deities are excluded by our founding documents. All US citizens, of all faiths, and even of no faith, are participants in our system of government.

We do not have a civil religion in this country. We have a nation. It is quite a different thing than a religion. Religions have worship. Nations have participation in its actions by its citizens. Religions have deities. Nations have laws.

There is no "civil religion" in the United States. There cannot be.
