People of the Book "Discovered"

People of the Book in the Qur'an refer to Jews and Christians.  Since Christians eat pork and drink wine, Muslims claim they are not the People of the Book but in Surah 3:110 it says "... If only the People of the Book had faith, it were best for them: among them are some who have faith, but most of them are perverted transgressors."  According to this verse among the Christians "are some who have faith".  In this book we have analysed who the true People of the Book among the Christians are who do not eat Haram but follow the Book.
