Acts 14:4

The "apostles" were Paul and Barnabas. Luke used the word "apostle" in a technical sense to describe the Twelve apostles plus Paul in Acts. He also used it less frequently in a non-technical sense to describe any believer sent out into the world with the salvation message (e.g., Acts 14:14; cf. Romans 16:7; 2 Corinthians 8:23; Philippians 2:25). There were only 13 men with the office of apostleship, but there were many others who, with more or less gift, did the work of an apostle. Similarly there were some with the prophetic office, but many more with prophetic ministries. [Note: See John E. Johnson, "The Old Testament Offices as Paradigm for Pastoral Identity," Bibliotheca Sacra 152:606 (April-June 1995):182-200.]
