"More than four-in-ten Catholics in the United States (45%) do not know that their church teaches that the bread and wine used in Communion do not merely symbolize but actually become the body and blood of Christ."
Here. That's half of all Catholics. And the teaching is mentioned every bloody week. Or at least alluded too. Or at the very least, was while I was a regular church goer some 15 or 20 years ago. But since probably 45% of self-identified Catholics are "lapsed," I guess it makes sense.
The gist of the story is that the pious have a piss-poor knowledge of their religion, at least as far as the the 32 questions on the Pew Research Center’s Forum on Religion & Public Life survey.
Who is knowledgeable? (Drum roll, please).... turns out athiests and agnostics (A/A) answered 20.9 of the questions correctly. They were followed by Jews and Mormons. It gets really ugly when you look at the 12 questions on Christianity: A/A answered 6.7 correctly. Christrians, who might expect to be somewhat of an expert on the topic, answered 6 correctly. Mormons (7.9) and white evangelicals (7.3) blew the field away.
Two-thirds of respondents actually indicated that teachers weren't permitted to teach the Bible in school, even for its literary and historic aspects. This is dead wrong.
It seems that for a great many, religion truly is a leap of faith.
