That quote is almost exactly what Charles Taze Russell said almost 100 year before.
He believed that the bible could not be understood from the 2nd century (or so) on until He was given understanding that no other man had.
This is very similar to what the WTS believes today.
The funny part is, they can't seem to figure out WHAT they believe.
Just consider all the doctrinal changes the WTS has been through in the last 100 years. (or 16 years for that matter)
It's very clear that none of them have been given special understanding above that of the common man reading the bible.
