Apart from Saul and Barnabas (see Acts 11:26), it is not clear which of the men were prophets and which of them were teachers. It is possible that all of the men served in both roles,1 or that the term prophet denotes the office and teacher the manner in which the office was exercised.2 In either case, the identities of the different men serve to showcase the diversity of the church in Antioch.3
1 Now there were in the church at Antioch prophets and teachers, Barnabas, Simeon who was called Niger, Lucius of Cyrene, Manaen a lifelong friend of Herod the tetrarch, and Saul.
