Folk celebrations of various Christian festivals and popular beliefs in various saints. It is, for instance, quite clear that a popular saint in many Slavic countries, St Elijah the Thunderer, is a replacement of old thunder-god Perun. Likewise, traces of ancient deities can also be found in cults of many other saints, such as St Mary, St Vitus, St George, St Blaise and St Nicholas, and it is also obvious that various folk celebrations, such as the spring feast of Jare or Jurjevo and the summer feast of Ivanje or Ivan Kupala, both very loosely associated with Christian holidays, are abundant with pre-Christian elements. These beliefs have considerable religious and sacral significance to the people still performing them. The problem is, of course, that the elements of pre-Christian religion are hopelessly mixed into popular Christianity.
For the last few decades, Slavic paganism has gained limited popularity among the Russian public, with many web sites and organizations dedicated to the study of Slavic mythology and some who openly call for "returning to the roots."
Most of the neopagan movements take place in Russia and Belarus, but they also take place in other Slavic countries like Serbia, Slovenia, Slovakia, Poland, Croatia and Ukraine.
