Steve Ray has posted 35 Questions for "Bible Christians". Apparently, he believes these questions expose the internal inconsistencies of Protestantism. TurretinFan has already provided responses to each of the questions which can be found here, but I thought I would add a few comments of my own. 

Question 1: Where did Jesus give instructions that the Christian faith should be based exclusively on a book?

Answer: If by "Christian faith...exclusively on a book" Steve Ray means to ask why do we believe the Holy Bible is the only certain and infallible rule of all saving knowledge, faith, and obedience that constitutes salvation, the answer is quite simple. Scripture is infallible and inerrant and serves as the guiding rule because it is theopneustos, God breathed (2 Tim 3:16). Meaning, there can be no higher rule of faith because of what it is, the very Word of God. If Tradition cannot be demonstrated to be of the same nature as Holy Scripture, that is, if one cannot prove Tradition is, in and of itself, God-breathed, then it must be subordinated to Scripture. Until someone can prove Tradition is theopneustos, he has no basis to claim it is binding on the conscience of the believer.

The answer, therefore, to the question is simply this: the exclusivity of the "book" in the Christian faith is given preemince because it is God-breathed. There is no other authority on earth that supersedes the very Word of God.
