It’s not every day that you hear of a legal dispute about whether a certain divinity is or isn’t a god. This may be because our states – at least, Australia, the UK and the US – have no formal obligations towards gods, and will generally refuse to comment on the true divinity of a god in the interests of protecting religious freedom.
The Roman republic had it the other way around. There was no official obligation for the state to tolerate religions, but the state was formally obliged to serve gods. John North, in his article, “Religious Toleration in Republican Rome,” has argued that while the Romans were generally tolerant in practice, the concept of “religious toleration” as a moral obligation was absent from Roman thought:
We certainly do not know at any period of any theoretical principle of allowing plurality of worship or belief. The toleration, if that is what it was, was a function of situation not theory.
