I never considered myself to be any sort of a minister.
During the mid-1970s, they went through that phase where, for a few years, only elders were supposed to be referred to as "ministers." At the same time, the "Ministry School" was renamed the "Theocratic School", and the "Kingdom Ministry" was renamed the "Kingdom Service."
Then, several years later, the WTS did (yet another!) back-flip, and restored the term "minister" to include everybody. I remember being less than impressed with them for using some of the same arguments to restore the previous use of the term "minister", as they had used in justifying its change several years before.
It all made absolutely no impression on me that we were all now once more "ministers", as I think by then the old Bull#h%t Barometer was beginning to kick in!
Bill.
