It is my understanding that the office of apostle is continued in what we now call a bishop. However, we also speak of being in a post-apostolic era when it comes to distinguishing public and private revelation.
Even during the first century people other than the twelve were called apostles, Paul and Barnabbas, for example. How can there be a post-apostolic era if the office was intended to be passed on?
I understand the difference between those who lived with Jesus those three years and apostles who didn’t. I can also justify including Paul with them because of his experience on the Damascus Road. However, Luke, Mark, James, Jude and whoever wrote the Letter to the Hebrews didn’t live with Jesus and their writings are included in public revelation so they had to be apostles in the same sense as the twelve.
Pleasee help me make some sense of this.
