Dan and Jon discuss the relevance and impact of Christianity in the modern world. They delve into how aspects of Christianity have influenced society, not only in superficial ways like our calendar, but in deeper things such as values, moral codes, and societal norms. The hosts reference various sources, including notable historians and authors like Tom Holland and Yuval Noah Harari, asserting that many fundamental beliefs and values in Western society, such as the sanctity of life and the concept of equality, have their roots in Christian teachings. That may make Christianity relevant in modern society, but does it make it true?
