The task of a teacher was to teach (Romans 12:7). Teachers were responsible for explaining and applying God’s Word. Saul and Barnabas are listed as those who taught in the church in Antioch (Acts 11:26).1 In Reformed theology it is understood that the office of teacher and pastor is one and the same (Ephesians 4:11; 1 Timothy 3:2; 1 Timothy 5:17).
