[The Apostles] gave us the authoritative teaching by which the church continues to live to this day, and that is the only teaching we will need until Jesus returns. We know that new apostles won’t appear since Paul specifically says he was the last apostle (1 Cor. 15:8). And when James the brother of John died (Acts 12:2), he wasn’t replaced. Apostles, in the technical sense, are restricted to those who have seen the risen Lord and have been commissioned by Him, and no one since apostolic times fits such criteria. The apostles were uniquely appointed for the early days of the church to establish orthodox doctrine. There is no warrant, then, for saying there are still apostles today. Indeed, if anyone claims to be an apostle today we should be concerned, for such a claim opens the door to false teaching and to abuse of authority.
