jp1692 : Does the NWT actually have the phrase “governing body” in the text of the Bible or is it just in that index?
Good point, jp1692. "governing body" is only included in the overview, it is not part of the translation. Acts 15:22 (NWT Study Edition) reads:
Then the apostles and the elders, together with the whole congregation, decided to send chosen men from among them to Antioch, along with Paul and Barʹna·bas; they sent Judas who was called Barʹsab·bas and Silas, who were leading men among the brothers..
Compare this with the Gideon bible here:
Then it seemed good to the apostles and the elders, with the whole church, to choose men from among them and send them to Antioch with Paul and Barnabas. They sent Judas called Barsabbas, and Silas, leading men among the brothers
