Iit is not a secret, but the country of Ukraine is generally believed to by far, have more practicing Believers than any other country in Europe with the exception of maybe one other.
In comparison, when Russian’s celebrate Orthodox Easter, in the recent past about 2-3% of the population will attend a service, which is only slightly less than many countries in Western Europe.
In Ukraine the percentage is between 22% and 25%. In this sense, Ukraine isn’t just one of the most Jewish friendly countries in all of Europe, it is also roughly the “Bible Belt” of the continent of Europe. Only Norway comes this close.
