So we see the Bible makes all of the above claims about itself and how it is not to be modified.
More accurately, some books of Bible records claims made by men about scripture and the Word of God.
But the Bible as you have read it did not even exists at the time any of the claims were made. It is not a trivial matter to say which text of which Bible books the quotes you reference even refer to.
For whosoever shall keep the whole law, and yet offend in one point, he is guilty of all. - James 2:10
What part of the Bible corresponds to the whole law as mentioned in James 2:10? Not the whole Bible, and certainly not James itself. Did James consider Acts, or any of Paul's letter's to be part of the 'whole law'. Almost certainly not.
You seem to have grabbed ahold of the fundamentalist's view of the Bible. Namely that the Bible is a monolithic tome that has existed through all of history. That view is clearly wrong. I don't feel any particular need to defend such a view.
Under a government which imprisons any unjustly, the true place for a just man is also in prison. Thoreau: Civil Disobedience (1846)
The apathy of the people is enough to make every statue leap from its pedestal and hasten the resurrection of the dead. William Lloyd Garrison.
If there is no struggle, there is no progress. Those who profess to favor freedom, and deprecate agitation, are men who want crops without plowing up the ground, they want rain without thunder and lightning. Frederick Douglass
