See post #91. Non-Christians often vastly overestimate Christians’ knowledge of their own doctrines, for several reasons:
– Most people speaking about Christianity in the news are ministers/priests/Popes, who presumably know more about the Bible than the average Christian (although I recall Jerry Falwell saying (during a denunciation of Islam) that Moses was a man of peace)
– Most of the non-clergy speaking about Christianity in the news are evangelicals, who necessarily take the Bible more seriously because they believe it to be literally true, but they comprise only about 13% of professed Christians
– Most people do not get into deep discussions of religion with acquaintances of different faiths, except online. And Christians who participate in online debates are self-selected for above-average knowledge and interest in the Bible
So most of a non-Christian’s encounters with a Christian speaking or writing about Christianity are not with the typical Christian. But as the survey showed, the typical Christian doesn’t know the first thing about the Bible, let alone the nuances of Biblical interpretation that separate denominations. And assuming participation in the survey was voluntary, even those dummies were self-selected for above-average interest in the subject.
On a personal note, my mother and grandmother were Catholics, and often lamented the fact that services were no longer in Latin. I asked them whether they understood anything the priests were saying, and they said no*, but it sounded so beautiful.
*Except for the demands for increased donations.
