Well, sort of, in a Masonic kind of way, as this article from the New York Times reports.

An excerpt.

MOSCOW — In an apparent attempt to use shared history to make a case for closer ties, President Vladimir V. Putin attended religious ceremonies in the Ukrainian capital on Saturday to commemorate the 1,025th anniversary of events that brought Christianity to Ukraine and Russia.

At a reception in Kiev, the capital, Mr. Putin spoke of the primacy of the two countries’ spiritual and historical bonds, regardless of political decisions that often divide them. Relations have been rocky in part because of attempts by Ukraine, a former Soviet republic, to formalize its political and economic ties with the European Union.

“We are all spiritual heirs of what happened here 1,025 years ago,” Mr. Putin told church hierarchs at the Monastery of the Caves in Kiev, one of the holiest sites of Orthodoxy, according to the RIA Novosti news agency. “And in this sense we are, without a doubt, one people.”

Mr. Putin’s trip was also the latest sign of the deepening ties and common agenda of the Kremlin and the Russian Orthodox Church. ..

The church’s views have increasing resonance in the political debate in Russia, where Parliament adopted laws in June banning “gay propaganda” and the adoption of children by foreign same-sex couples.

In a film called “The Second Baptism of Rus,” shown recently on Russian state television, Mr. Putin credited Prince Vladimir’s choice of religion with “building a centralized Russian state,” something he sees as a cornerstone of his leadership. Mr. Putin recalled the story of his mother having him baptized in secret after his birth in 1952 because of Soviet repression of the church.

He described Communism as “just a simplified version of the religious principles shared by practically all the world’s traditional religions” and said that today’s turn to religion was “a spontaneous movement from the people themselves to turn back to their roots” in response to the ideological vacuum after the Soviet Union’s collapse in 1991.
