What is hard to understand is how Jesus’s FDS can be removed with the human push of a button or even appointed.
It was easier to understand that mysteriously a person is anointed by God thereby appointed by God as FDS.
Since WT changed the definition of FDS, the definition is subject to change. Which means that the WT definition of FDS can change again.
It does make sense though that in the 1 Century although everybody was anointed, there was only a handful of decision makers having authority over everybody aka a governing body or the Apostles. They were the ones writing the Bible under inspiration, etc.
Sleepy now. May add more in another post.
