Interesting view isaac, but I don't understand how you reach the conclusion that "the whole assembly" decided what should be done.
Acts 15:6 says "And the apostles and the older men gathered together to see about this affair".
So it wasn't the whole congregation gathering to decide the outcome, but only the apostles and the older men.
Once the decision is made, Acts 15:22 now says "Then the apostles and the older men together with the whole congregation favored sending chosen men from among them to...".
So the congregation helped with the choosing of the men by some sort of voting system I imagine, but it was after the apostles and the older men had discussed matters and reached a decision to communicate to the rest of the congregations.
Then verse 23 says that the letter is from the apostles and the older men, not from the whole congregation in Jerusalem, the scripture describes the beginning of the letter, "they wrote: “The apostles and the older men, brothers, to those brothers in... ""
Verse 28 says "For the holy spirit and we ourselves have favored adding no further burden to YOU, except these necessary things, ...", in this scripturee it is obvious that "we ourselves" refers to those that wrote the letter and made the decisions which verse 23 described as "the apostles and the older men".
It is crazy to think that whole congregation would be debating to reach a decision, that is chaos and not consitent with how Jehovah structured his earthly organization throughout time.
