Certainly, Nicholas and Alexandra were Christians. Certainly they were Orthodox. Maybe, they were even saints. That they were regarded for so long as "political criminals" is a direct outgrowth of a terrible notion of governance: lay investiture of bishops. You would not have had to accept Roman appointments (and I feel confident you would not) of your bishops to avoid this. Could you not have convened synods beyond Russia's borders of Orthodox religious leaders to name some of your genuinely holy men to be Russian bishops? Otherwise, how do you avoid your ancient Church becoming a marionette of whoever happens to be running government?
Whatever the truth may have been as to Nicholas and Alexandra (and that truth may well have been sainthood), it did not change after their deaths according to which gang of Marxist hooligans happened to wield the most effective bunch of weapons from rifles to the battleship Aurora.
Did Tito also have a say in the appointment of Serbian Orthodox bishops in Serbia? Why? How do you choose bishops here since the US government is certainly prohibited by its own First Amendment from having a say in who your bishops will be.
I concede that I am not always respectful in my posts but these are, I think, fair questions and deserve candid answers.
