First of all you said christian nationalist govt, not orthodox christian nationalist govt. Anyway, to be honest, i find it rediculus. Having the same government with Russians or Bulgarians etc because of orthodoxy makes no sense. As i learned recently, Russia alone has more than 190 minorities and some of them are Buddhists, Muslims etc. We have Muslims too. And what language should we use? That would be like the Babel story...
Having said that, the state and the church in my country are not distinguished... So your question was good 👍
