These people are stuck in first century civilization.
The way they view our secular society, they could say we represent an uncivilized society altogether. Pre-Mosaic, if you will.

They're just trying to live by their Book, while we only give lip service to living by our Book. They see us as complete heathen/heretic hypcrits, devoid of morals. They have a point.
It's all a matter of perspective.
