To my shame I have studied a lot about Christianity. Orthodox Christianity (Russian Orthodox) is much much stricter then any other religion. They have four 40-day fasts a year when they eat neither meat nor dairy.
Even though USSR was an atheist state, many Russian Orthodox traditions continued. Many of my peers (I left USSR at age 12) were very severely physically abused.
