As is very typical you, this is nothing original, but has been tried before, and others who have hypocritically tried to impugn the credibility of my stats (http://www.peacebyjesus.com/RC-Stats_vs._Evang.html) were shown to be wrong.
While you brazenly infer that i am lying with stats, Catholic sources themselves reference polls which i do, as valid, in seeking to sound an alarm. And RC apologists also use stats when it favors Rome, without being questioned or charged with manipulation by their own (though they were shown by others to have engaged in misrepresentation)
As for the book, in my case such a book can actually validate my use of stats, some of which come from Catholic-commissioned surveys, as it not manipulative use of misleading questions that testifies to the inferior state of RCs, but the censuses of what survey after survey have shown, without any real contradiction. And when i found significant variance in response to the issue of the nature of the Eucharist, i included them.
Moreover, while the statistics show a superior degree of conservative views and unity and of commitment among evangelicals, they as well as a linked supplementary work also testify to the declension of the evangelical church, as the positive number should be much higher.
Thus your inference is due to your myopic cult-like commitment to defend Rome, and is at odds with more objective and far more official RC organs, who rather than place their head in the sand, admit the declension of Rome, and which is also happening in evangelical faith, as prophesied. (2Thes. 2:3) In fact, one RC here responded to the statical testimony of the inferior spiritual condition of RCs by using it to affirm that Rome is the OTC, based upon that prediction!
