There really are too many smart people who are simply not digging enough, or even reading between the lines.

But if that affects whether someone is saved or not, that would mean that faith in Jesus's death and resurrection would not be sufficient for salvation, which would be a problem for Evangelical theology.

For Catholicism, which has a works element in addition to a faith element, this view would also not work. (being naïve is not a mortal sin).
