"How do you think believers managed to keep alive faith in their heart when religion was forbidden in Russia?
Some people continued to go to church regardless of persecutions, but there were also many secret Christians, who practiced their religion in a clandestine way, without attending church services but keeping faith in their heart. Indeed, people in the Soviet Union had no direct access to Christian literature or to religious education. But Russian culture, including music, painting, literature and poetry, was so imbued with Christian ideas that it continued to become the bearer of religious message even in the times when religious propaganda was officially forbidden. For example, people could not access the works by the Church Fathers, but they could read Dostoyevsky’s Brothers Karamazov, where many pages are dedicated to the presentation and interpretation of patristic ideas."
This is why a good, classical education steeped in Christian tradition matters!
