The Bible was not compiled until the 4th century?!*?
What planet have you been living on?
The Old Testament Books were written centuries prior to the 4th century A.D. Those Books made up The Bible in the days of Christ's Apostles, and also long before they were born. The word 'Bible' simply means 'book' from old words like biblos, biblia. But when speaking of The Bible in the God's Holy Writ sense, it most certainly includes all the writings He sent through His servants of Israel and of Christ Jesus.
EVEN with the New Testament manuscripts, they go back further than 4th century A.D.!

Even within the period that runs from c. A.D. 100-300 it is possible for paleographers to be more specific on the relative date of the papyrus manuscripts of the New Testament. For about sixty years now a tiny papyrus fragment of the Gospel of John has been the oldest "manuscript" of the New Testament. This manuscript (P52) has generally been dated to ca. A.D. 125. This fact alone proved that the original Gospel of John was written earlier, viz. in the first century A.D., as had always been upheld by conservative scholars.
We now have early and very early evidence for the text of the New Testament. A classified list of the most important manuscripts will make this clear. Numbers preceded by a P refer to papyri, the letters refer to parchment manuscripts.
