I would argue that Jack Chick and the parent poster above, in fact, do not believe in The Bible, despite being Christian.
That is an extraordinary statement, which requires extraordinary proof, which I will now offer.
Most Christians in this world, by number, are Roman Catholic. The Catholic Bible was defined at the Synod of Hippo and the Council of Carthage as being the 27 books of the New Testament, and the 47 books of the Septugiant- a Greek version of the Old Testament translated in the days of the Greek King Alexander to be the scripture for Greek-speaking Jews in his empire.
The "11 extra books" most publishers today put between the Old Testament and the New, were originally part and parcel of the Old Testament. In fact, one wasn't originally a book, but instead just a few extra stories in the Book of Daniel.
Protestantism, in particular Martin Luther, changed all that during the Reformation- actually EDITING scripture. The reformers wanted scripture edited down even further (after all, James Chapter 2 kind of lends lie to the entire concept of the 5 solas, and the first chapter of the Gospel of John indicates to anybody able to read that the Word of God isn't a book, but a person) but the people wouldn't stand for editing the New Testament. So they went with the Jewish Old Testament from the Synod of Jamnia instead- which only contains those books Ezra the Priest collected when the Jews returned to Israel from Babylon.
In return, since the 11 extra books had been considered of secondary importance by even Catholic scholars up until then, the Council of Trent formally defined the extra works.
Many important Catholic theological concepts, such as praying for the dead, the Communion of Saints, and even some of Christ's own sayings, come from the historical period of the Revolt of the Maccabees, which is included in those 11 extra books. It's little wonder that in their attempt to shake off human authority, the Protestant Reformers wanted to hide this.
And so today, there truly is great difference between certain denominations of Protestantism and that of Catholicism. But you can't tell me that the fundamentalists are truly Biblical- because they simply don't have the whole Bible. Thus, it's little wonder that we get horrifically under-researched Chick Tracts like "The Death Cookie" (though I really have to wonder, after reading that one, if Jack Chick has ever read John 6.)
