Interesting to see your thoughts and experiences. Thank you.
Since my focus is on the most current interpretation of the derivation of "appointment in 1919", I did not visualise that the Jonadab class would be pertinent, and perhaps could indeed form a distraction. As I noted, this presentation does not delve into every nook and cranny at every step, and I make no apologies for that.
If you wish to see references to the "Jonadabs" I refer you to my Study at:
The file is searchable.
I suspect that the name "Jonadab" fell into disuse in the mid to late 1940s when the designation "Jehovah's witnesses" was extended to the "Great Crowd". Under Rutherford, the term "Jehovah's witnesses" was confined to the anointed 144,000.
I had thought of including a "circular reasoning" graphic. Maybe I should have followed through with the idea. (Why do you believe what the Bible says? -- Because it's in the Bible) (How do you know the Bible is inspired - Because the Bible says so) (How do you know the Society was selected by Jehovah and Jesus in 1919? - Because the Watchtower's interpretation says so -- How do you know this is valid? -- Because it was selected in 1919).
Please do not worship the Bible as if it is a god.
