Some supporting details from Acts 15. If we would suppose Paul went to see the Governing Body of the that time, let us see who was part of that comite, and the ideas they fostered. Acts 15:5 reads: "Yet, some of those of the sect of the Pharisees that had believed rose up from their seats and said: “It is necessary to circumcise them and charge them to observe the law of Moses.”
So the socalled Governing Body had Pharisees amongst them that clearly propagated sectarian ideas...
Now maybe some smart cookie says: they were part of the congregation but not of the Governing Body, as the meeting started only in verse 6. Well, let us read what happened in that meeting, verse 6 reads: "And the apostles and the older men gathered together to see about this affair. 7 Now when much disputing had taken place..."
Clearly quite a big part of the apostles and older men had the same ideas as the Pharisees, otherwise there would not be such a dispute.
Do you like the idea to be part of an organization that is led by Pharisees from the very beginnings? If you don`t like the idea, maybe Acts 15 is not a great support for the Governing Body concept.
