Notes 

Notes on sources for the article:
 Too many times I have referenced sources as cited from random websites. This is because I do not have access to many of the sources firsthand; I hope you can assist here 
 Barna, p189, mentions "7 out of 10 believers..." but I can't view the rest of this quote in the Google Books preview...
 Lutzer is apparently mistaken when he states 8 out of 10 Americans believe the phrase appears in the Bible (p173, citing Barna, however I can't view the footnote)
