Personally I believe the office of apostle is being done by missionaries. It is simply a name change. I will admit though, that the diminishing of the spiritual gifts has weakened the work of the apostle/missionary.
The office of prophet has also suffered because of the diminishing of the spiritual gifts. Though the office of prophet seemed to disappear the work of the prophet did not. They just were not called prophets.
The “second coming” of the spiritual gifts at the beginning of the last century has opened the door for these offices to come back with power. There needs to be constant use of discerning of spirits to make sure we are dealing with the real article and not some falsehood perpetrated by con men and/or our spiritual enemy.
