Scripture cannot contradict itself because GOD cannot contradict HIMSELF.
If there appears to be a contradiction in Scripture with a verse compared to the rest of it, then it’s obvious that the verse has been misinterpreted.
And any books or writings that contain contradictions to the current 66 books of scripture or proven historical accuracies must be considered not inspired by God and therefore not to be used for anything spiritual.
Apparently individual Protestants can have wildly divergent interpretations of scripture and still be infallibly guided by the Holy Spirit.
