Well, those writings have led thousands and thousands to a knowledge of the Truth: that one particular Jew known as Jesus The Christ is The Lord and Most Graceful Savior of households who believe in Him from the deserved consequences of eternal condemnation in Hell.). That’s got to carry some “historical” weight.
There are literally hundreds of sects in the world, each with its own bizarre "holy writings" (e.g., the Koran, the Book of Mormon, the Tibetan Book of the Dead), about which you could make the same claim.
The fact that a "book" has followers does not in any way confirm the truth of that "book."
