One notable difference between apostles and prophets is similar to a primary difference between evangelists and pastors. In the New Testament, prophets appear to work exclusively within a local church, while apostles have a much broader ministry. For example, in Acts 13, Paul and Barnabas are referred to as prophets of the church at Antioch until the Holy Spirit says, “Set apart for me Barnabas and Saul for the work to which I have called them” (Ac 13:2). From there, they are sent out as messengers (or apostles).
At times prophets would speak new revelation from God. Other times they would expound on previous revelations. In other words, they always spoke for God, but they did not always speak new revelations.
The third distinction of prophets is the practical nature of their teachings. Apostles spoke general doctrinal messages while prophets spoke on a more personal and pragmatic level.
Those distinctions aside, the prophets are similar to the apostles in that they are not perpetuated. Perhaps the gift of prophecy still exists, but the offices of both apostles and prophets have since given way to evangelists and pastors. Again, the foundation has already been laid. By the end of the New Testament, we do not read of Paul or anyone else ordaining new apostles or prophets. Instead, we read of them instructing evangelists as well as pastors and teachers.
