Motema
I found this one quote that might be of help - not sure if it is the one you are looking for.
"Thus the Bible is an organizational book and belongs to the Christian congregation as an organization, not to individuals, regardless of how sincerely they may believe that they can interpret the Bible. For this reason the Bible cannot be properly understood without Jehovah's visible organization in mind." Watchtower 1967 October 1 p.587
I'll see if I can find any others for you.
All the best
