Even if you accept the new FDS identity as the GB, there was no GB until 1975!!! That's what I see as the largest glaring hole in this new doctrine.
True, but that is why they define the F&DS as an arrangement. The Governing Body is, since it's inception, synonymous with the Faithful and Discreet Slave, but the Faithful and Discreet Slave is not the Governing Body. It is an arrangement of responsible anointed ones serving at God's Watch Tower Organization.
