Do they have it right.?

Theologically there is errors in the Amish and Hutterites religions. But other then that do they have it right. I mean if they found and corrected the errors in there teachings i think they would be the ones that have it right. They are probably the most likely to keep theyre faith when it will become so hard to do so in the future. They are isolated from worldly fads and natures and stick to there beliefs. So if they had the right religious beliefs, who thinks they have it right.
