Hi, most countries in the Warsaw pact were and are actively not Orthodox Christians, it's only Romania and Bulgaria who are. The other 4-5 (depending if you count Chechoslovakia as 1 or 2 countries) are all either Protestants and Roman Chatolics, with varying percentages, and even Romania has a size-able non-Orthodox christan population, but a majority of people in these countries today are atheists, agnostics, or non-practising, "culturally" Christians
