Since you seem to hold a strong conviction, could you please make more explicit what concretely one would not know / missinterprete regarding the Western culture, not knowing anything about those concepts you listed, but knowing the bible itself back and forth? And to what excent one would need to dive deep into those concepts?

Or in other words: What fundamental concepts in Western culture will we understand if we take you on your word and spend time into understanding those concepts?

Bullet points / pointers would be enough already!
