An accusation of circular reasoning is far too simplistic. Hence the need to reduce it to the bible says so so it must be true. That isn't what's asserted. What's asserted are many logical points which go together to make a consistent whole.
If that were not true, it would be like saying that science is true because science says it is. As far as I know that holds true, but we then look into the detail and can discern evidence that supports other evidence: where conclusions are drawn.
