Are there differences in the way Buddhism and Theism treats scripture?

Historically, Buddha rejected the validity of the Vedas, I suspect there might be some differences in the way scripture is treated in Buddhism and other religions, especially Theistic ones. For for example does Buddhism treat its scripture as the final Authority on the nature of reality? Is something considered true just for the reason that it is said in Scripture? Can scripture be argued with? Is it, in some sense, eternal?
