"Bearing Thorough Witness About God's Kingdom", page 115, paragraph 19:
"That peace and unity now existed in the Antioch congregation was clearly evident. Rather than contending with the brothers from Jerusalem, the brothers in Antioch treasured the visit of Judas and Silas, for it was only after "they had passed some time, they were let go in peace by the brothers to those who had sent them out," that is, back to Jerusalem. * (Acts 15:33) We can be sure that the brothers in Jerusalem also rejoiced when they heard what the two men had to say about their journey. Thanks to Jehovah's undeserved kindness, their mission was happily accomplished!"
Footnote reads: "In verse 34, some Bible translations insert words to the effect that Silas chose to remain in Antioch. (King James Version) However, such words appear to be later additions." [Can they cite a source on that statement? Just being curious here, not critical, because I don't know.]
Acts 15:40: "Paul selected Silas and went off after he had been entrusted by the brothers to the undeserved kindness of Jehovah." Guess the issue is, did this 'entrusting by the brothers' occur in Antioch or Jerusalem?
Note that the 'bt' book, as it is called in shorthand, says Silas went back to Jerusalem. If this is true, then in order for Paul to have selected Silas to come with him on his missionary tour thereafter, assuming Paul was still in Antioch (which clearly he was 'after some days', according to verse 36--likely the Bible would've mentioned it if he went back to Jerusalem) he either would have had to (a) go back to Jerusalem to pick him up or (b) wait for him to come all the way from Jerusalem. Unless (c) Silas went to Jerusalem and came back 'after some days' and was on hand to join Paul.
The context of Acts 15:35-41 makes it clear that Paul was still in Antioch, hence how he could get right into heading to Syria and Cilicia, which would have been a long journey from Jerusalem. It seems more logical that Silas really did stay in Antioch. Any thoughts on this? Is the Society just stretching it to make it look like everybody has to report back to Jerusalem (or shall we say, Brooklyn)? Or did Silas more likely go back to Jerusalem after all?
