What would you call a form of government where the community governs itself? [closed]

Let us suppose that there was a society that existed on a communal level where there weren’t really any formal official laws, but rather the community sort of liquidly governed itself, using de facto social norms and social values that are strongly ingrained and maintained in the community through tradition and culture, and instead of formal laws everything was basically fluidly governed by the community at large through what is de-facto? Basing governance on what is commonly accepted by the community and having the community enforce it by itself without an external government. This community would place a religion at its center, and the culture and values within it would be derived from that religion.

I think the best word for this would be anarchy. Colloquially, "anarchy" is associated with chaos and disorder, but linguistically and in the context of many political theories (e.g. anarcho-communism) anarchy simply means the absence of government.

Two definitions given by Merriam Webster:

a) absence of government

c) a utopian society of individuals who enjoy complete freedom without government

While this term doesn't capture your point about values and actions being based on a shared religion, it also doesn't preclude the centering of religion in this community and is the best way to define the "form of government" or lack thereof.

If you want a single word to describe not only the way the community is governed, but the community way of life more broadly, I would probably say the best word would be "Christian*-anarchist-communism". Someone in the comments of the main post suggested syndicalism, but I don't think this is quite right as it implies control of the economy by workers.

*or whatever adjective applies to the religion of the commune

Your description of this community sounds much more like anarchist communism as described by Kropotkin in "The Conquest of Bread" wherein it is not just the workers who have seized the means of production who thus enjoy the fruits of their labor, but rather that the fruits of all labor are shared and applied towards the well-being of all members of the community.

"All is for all! If the man and the woman bear their fair share of work, they have a right to their fair share of all that is produced by all, and that share is enough to secure them well-being. No more of such vague formulas as "The right to work," or "To each the whole result of his labour." What we proclaim is The Right to Well-Being: Well-Being for All!
