Russian President Vladimir Putin today visited the Rogozhsky spiritual center of the Old Believers in Moscow, the first head of state to visit the cloister in 350 years. The Old Believers, or Old Ritualists, split from the Orthodox Church in 1666 over a change to Christian rituals that had been performed for centuries. The changes were made by Patriarch Nikon of Moscow between 1652 and 1666.
