Aristotle probably would have approached our ideas of church-state separation, but not gotten there. I say this because he was a precursor of modern democracy, but never would have come up with the US Constitution.

He probably would have supported the free exercise clause to a large degree. Relatively few religions are harmful to society, and he would not want to punish any religion that was not harmful to society. This means almost all religions of his time. OTOH, if he lived now he might well see fundamentalist Christianity and Islam as a threat, and support a moderate suppression of them.

About the establishment clause. I think he might support a moderate establishment of religion. He might support the establishment of a religion that helped society run, like the Roman state cults. His own religious beliefs were probably deistic--it's not that likely that he took Zeus and Hermes very seriously. Now deists rarely feel the need to have their beliefs supported by the government. So he would not support the establishment of beliefs on the grounds that they were true. It is unlikely that he would be an activist who wanted "In God We Trust" taken off our money, etc.

So in sum, I think Aristotle would have approved in theory the policies that the government of the Roman Empire put into practice. The church-state views of the founders of America have been argued left and right; isn't it a nice change to ask the same question of a founder of Western philosophy?
