Tonus
RBC,,, I think it could be relating to the former Regional Build Committee.
Which around a decade ago was replaced by the LDC committee.
A centralized version of the former.
With the latter the Borg assumes control of everything and $$$,, with the exception of only a few thousand dollars in the local congregations accounts to cover a few minor repairs.
This new arrangement all major repairs or whatever have to be approved by headquarters.
With this new arrangement the Borg can assume control over ALL of its properties anytime.
Hope this helps. Someone please correct me if I'm not 100%. But I do believe its along these lines.
