I took it the other night, it is easy, but it also is not about Christianity, it is a quiz with no real purpose, yet it is being used as if it were a major study, with deep, meaningful results and implications.
Mormons, black Protestants and white evangelicals are the most frequent readers of materials about religion. Fully half of all Mormons (51%) and roughly three-in-ten white evangelicals (30%) and black Protestants (29%) report that they read books or go online to learn about their own religion at least once a week. Only a small fraction of all religiously affiliated Americans 6% of the general public and no more than 8% of any religious group say they read books (other than Scripture) or visit websites to learn about religions other than their own at least once a week.
Those are very sad and low numbers. How can you not read about your religion at least on a weekly basis? How can you "practice" your religion without knowing it?
The studies conclusions aren't clear and possibly they're not meant to be. PEW likes contention, destroying/undermining Western Civilization, and garnering headlines. They've obviously succeeded here.
ding we have a winner!
