"Buy muh cheaply printed, self-published book o' borrowed scholarly unbelief, please! I loves money!"
Scumbag.
As with his own obvious failure, your above is nothing more than the result of your failure to apply "the things that differ" principle in reading where he is coming from - your failure out of your personal animosity towards the guy because he does not hold to so called MAD and or where said so called MAD supposedly looks at things from.
One should ever strive to allow the views of others to challenge one to further reflect on one's own.
Go back and read early O'Hair - that was how he ended up recovering so much.
His having been ever willing to allow himself to try to learn something towards his own further and further understanding even from his greatly slandering enemies, back then.
His was a very rare trait. One that personal animosity only gets in the way of.
What books is IP attempting to sell when he defends justification by faith?
Or when he posts of his awe at the words in one hymn or another praising the Saviour?
No, brother; we each ought to try be a bit more objective as we look over at others.
The alternative is ever one's having ended up too easily self-blinded to what one is actually looking at.
That and guessing at and taking said guessing at as having been sound.
As O'Hair repeatedly showed through his fine example in the Lord after each his encounter with friend and foe alike - hope for the solving of any issue; and hope for even greater clarity in "the things that differ" is ever to be found in the objective application of "the things that differ" principle to begin with.
And as the Apostle Paul put it - "in all things."
No matter who points us back to the need to apply the principle - even when such had not even been their intent, let alone, their practice.
