An examination of the NT/CGS shows that many met in homes, proven by Paul's greetings. I was always under the impression that the Book Study was not only vital but modelled after 1st cent christians and a critical part of the final outwork during the great tribulation. I believe that the biggest reason why it was cancelled can be found in the following quote:
km11/82p.1par.2AMeetingtoFortifyUsSpiritually While you regularly attend all other congregation meetings and participate in them, enjoying and benefiting from these, never underestimate the value of the weekly Congregation Book Study. The fact that this is an organized meeting of a smaller group contributes to its spiritual value. It allows for greater individual participation. There is often more time for scriptures to be looked up, read and discussed. Newer ones and children find it easier to participate and they progress quickly as they gain confidence in expressing their faith. Comments made by mature publishers on the more weighty material help to strengthen and fortify all in attendance. The interchange of encouragement at the book study invigorates all who support it, and a closer bond of union results.
A few observations while I attended the fist year of the change:
1) "It allows for greater individual participation" - to the contrary, people who frequently commented in the book study I oversaw, stopped commenting at the revamped meeting. It made my fade that much easier.
2) "There is often more time for scriptures to be looked up, read and discussed" - big concern, encourages thinking and reasoning. Good luck getting your well researched thought out comment at the Bible Study or wasted on 30 sec soundbites at the weekly Bible Highlights.
3) "Comments made by mature publishers on the more weighty material help to strengthen and fortify all in attendance." The biggest reason - too much additional personal research, espcially by CBSO's - they were putting their own stamp on interpretation away from the majority. I often heard of squabbles over how one CBSO made statemnst contrary to anoth CBSO - the Revelation Climax book was a greate example, add to that the brain addled CBSO who asked me "when were the changes made to the Climax book? was there a letter?"
If the book study was so central to fortification of faith, encuragement, progress, confidence and understanding - why do away with it? the reason - everybody in one spot is easier to control than breaking them up into 6 - 7 groups without control. The gas issue was lame (no disrespect to those who travelled great distances) but an all knowing God would have seen that gas prices would have dropped shortly after peaking. Adding the Family Worship night was also stupid - people quickly ran through the smallest amount they could (if they did it at all) and then settled down for a night of "House" and "24". I would way barely 1% are faithful to this.
