Can you believe in Christ but not in the authority and infallibility of the Bible?
You can try, but it will leave you on the horns of a very real dilemma: If you say you believe in Christ but doubt the Bible’s truthfulness, you are being inconsistent and even irrational. Christ endorsed the Bible as true and authoritative. Therefore it follows that if you give Christ a place of honor and authority in your life, to be consistent you have to give Scripture that same honor and authority.
Jesus and the Old Testament
What did Jesus think of the Scripture of His day, the Old Testament? Did He see it as authoritative? In Matthew 23:35, He apparently defines the Hebrew canon as the books from Genesis (Abel) to post-exilic 2 Chronicles (Zechariah), which encompasses the whole Old Testament in terms of the Hebrew chronology.
It is also important to note that Jesus never quoted or alluded to any apocryphal works. Why was this so? Bible scholar F.F. Bruce explains that the Apocrypha
were not regarded as canonical by the Jews either of Palestine or of Alexandria, and that our Lord and His apostles accepted the Jewish canon and confirmed its authority by the use they made of it, whereas there is no evidence to show that they regarded the apocryphal literature (or as much of it as had appeared in their time) as similarly authoritative.
Although this is admittedly an argument from silence, it is still significant that sixty-four times Jesus quoted or alluded to the Old Testament while He never referred to other sources. Christ put His stamp of approval on the Old Testament in several key ways.
