From my reading of Ray Franz's books , it would seem that there was an underlying conflict in the late 70's , with some members of the GB and associated committees pursuing a more liberal , mainstream agenda. For example , Ray published his 1976 WT article defining "sacred service" as including "good works" such as looking after family members and charitable activities and Ed Dunlap published the excellent "Commentary to the Letter of James" (never quoted nowadays by the WTS) stressing traditional Christian qualities. Both were purged in the late 70's.
Is it likely that a similar movement will gain ascendancy or do we assume that the present leadership will continue on the "high control" agenda?
