4:11 apostles. In a restricted sense, those who had been with Jesus and witnessed His resurrection (or received a special revelation of the risen Jesus) and who had been commissioned by Jesus to be founders of the church (Acts 1:21, 22; 1 Cor. 15:1–9). The word was also used in a broader sense of people sent out as delegates of particular churches (2 Cor. 8:23; Phil. 2:25), though these do not appear to be the ones Paul has in mind in this passage. See 2 Cor. 1:1 note.
prophets. The New Testament prophets conveyed special revelation to the early church. Their functions included prediction, exhortation, encouragement, warning, and explanation (Acts 15:32; 21:9–11; 1 Cor. 14:3). The teaching of the New Testament prophets and apostles laid the foundation of the church (2:20), and certain aspects of their work related to that unique task have been discontinued.
pastors and teachers. The two words go together to refer to a single set of individuals who both shepherd and instruct God’s flock. See “Pastors and Pastoral Care”at 1 Pet. 5:2.
