Another Question for Calvinists

If the notion of universal Divine causal determinism is to be believed to the extent that God causally determines “the moving of a finger, the beating of a heart, the laughter of a girl, the mistake of a typist – even sin”, indeed, “every thought, word, and deed in all of history”, as Palmer says, can it be rationally affirmed that the Scriptures are any more inspired than the works of Arminius, or Calvin’s Institutes? Wouldn’t this very question be just as ‘inspired’ as the Scriptures? If God has indeed causally determined “every thought, word, and deed in all of history”, wouldn’t that reduce the inspiration of Scripture to a redundant doctrine?
