So you say.
Who controls the Russian Church is irrelevant.
What is relevant is that the Ukrainian schismatic government Church attempting to take over is illegal in terms of Orthodoxy .
Putin’s attitude towards religion is purely utilitarian. The church’s function is to convince its people and normalise something that is unnatural - for example, a war against a “fraternal people”.
From the era of Stalin, the Russian Patriarchate has been closely cooperating with Russian secret services. That was Stalin’s deal. In 2002, Patriarch participated together with the head of FSB in the opening of the Saint Sophia Church in downtown Moscow which was considered an open recognition of their special relationship.
As to the rest of the nation, less than 5% of ethnic Russians are regular churchgoers.
