Top manager of Russian Orthodox Church as institution is Patriarch. His official statement about vaccination was clear:

"I am convinced that to be vaccinated or not is not a doctrinal question at all. This is a purely medical issue, a matter of personal choice and responsibility of a person, his life experience. In this regard, the abuse of pastoral power on this and similar issues is completely unacceptable, and even more so vaccination cannot be considered as a sign of apostasy. Even if the whole world becomes an arena of immune segregation, the church must remain free from such segregation and accept all people striving for Christ."

The head of Russian Orthodox Church is Jesus Christ, not some bureaucrat. So, priests are free to have their own opinions on whatever social or political questions. Orthodox church is purely religious hierarchy, not social or political. Most pastors in Russian churches warned their parishioners about harms of coronahoax vaccination and was more than sceptical about coronahoax as whole. Very few stopped church services during lockdowns. This is one of the reasons why Russia have one of the lowest vaccination rate in the world. There are a lot of priests who are openly fighting against accepting individual taxpayer numbers (something like SSN in US), QR codes and whatever digital NWO shit. Globalists are considered a threat to humanity and obvious puppets of Antichrist that will promise fake paradise on Earth in exchange for human souls. And of course none of pastors will ever accept such nonsences as gay marriage or other gender insanity. God created only men and women, as two distinct but compatible to each other flesh and spirit creatures, everything else is from Devil.

Top managers of Russian Orthodox Church often appear too servile to the state, but most priests at local levels are pretty based. Absence of Catholic-like total hierarchy with self-proclamed Pope on the top who could speak in the name of Jesus and push garbage into the faith perfectly protect Russian Orthodox Church against adding any political shit into the Orthodox faith.

So, yes, Russia will preserve Cristianity, Cristian view on the family and society and that is why it will stay white.
