Mmm - that is an over simplification of what a minority of Christians believe. Certainly not “most”. The Catholics, Orthodox, and all of the major Protestant branches have had rigorous critical debate on what is the Truth. Even those that shake out as Sola Scriptura and chose a more literal interpretations, have done so after debate. Their decision to go with a literal interpretation is still an interpretation.
Now, granted, a lot of the FOLLOWERS haven’t have these debates, but the founders and leaders certainly have. Indeed, the fact that there are so many Protestant flavors often stems from critical thought and debate being applied.
