Acts 15:23

The destination of this letter throws light on extensive missionary activity that had taken place, which Luke did not record. We know of the mission to Antioch, but Luke mentioned nothing about the evangelization of Syria. We know that Paul had done missionary work in Cilicia, but Luke did not tell his readers anything about it. Here we learn that there were churches in these regions already, as we may have assumed but now know for sure (cf. Acts 15:41). Antioch was the capital city of Syria and Cilicia, which Rome administered as a single province until A.D. 72. [Note: Neil, p. 175; The New Bible Dictionary, 1962 ed., s.v. "Cilicia," by E. M. B. Green.]
