As far as I know the criteria for a cult (religion) is that one take oath to a falsehood in exchange for group membership, group limitation on political coercion, and group emotional insurance, and the promise of some future (utopian) good.
As far as I know, taking an oath to sovereignty, reciprocity, truth, and duty for the promise of continuous goods and future transcendence for the self, kin, nation, and mankind is not a falsehood.
As far as I know the militia and the polity, under sovereignty, reciprocity, truth, and duty provide all those insurances.
As far as I know the an oath of reciprocity requires nor tolerates a falsehood.
The difference is we pay real costs for the militia, sovereignty, reciprocity, truth, and duty, and we pay no costs for the other than recitation of falsehoods for cults and religions.
