In order to ensure to citizens freedom of conscience, the church in the U.S.S.R. is separated from the state, and the school from the church. Freedom of religious worship and freedom of antireligious propaganda is recognized for all citizens.So in general, any blurting out of the phrase separation of church and state is echoic of that law and its meaning rather than Jeffersons letter to the Danbury Baptists.
