So we have divine right of kings (saintly, virtualy un-questionable and un-replaceable leader. You get rid of one his son takes over) and communism (work or we kill you, bad wages for all as you can't afford good wages for all, work for the 'greater good'). And a theocracy (heretics if you disagree.)

Frankly that makes it seem less likely they'd last till next week, let alone thousands of years!

Civil wars have been fought over the divine right of kings. The kings lose. Almost every time. Power does corrupt and it only takes one bad absolute monarch to lose a kingdom.

You have a highly millitarised and religious society that believe in the greater good. Recipe for disaster and very successfull rebellions. Once someone starts a revolt the army units sent to crush it are going to think 'Hey they have a point, the best thing for society would to be to kill this Praetor, he's [censored].' and join in. The community is more important than the state or their lives.
