The apostolic period extends from the day of Pentecost to the death of St. John, and covers about seventy years, from 30 A.D. to 100 A.D. The field of action is Palestine, and gradually extends over Syria, Asia Minor, Greece and Italy. The most prominent centers are Jerusalem, Antioch and Rome, which represent respectively the mother churches of Jewish, Gentile and united catholic Christianity.https://gracenotes.info/documents/topics_doc/apostolicage.pdf
The first problem is the suggestion that there was an apostolic age that began and then ended. But given that we can, with well-indoctrinated cognitive dissonance, suggest this Scripture is both the word of God and is not, it doesn’t surprise me one bit that some have defined an apostolic age:
"... And God has appointed in the church, first apostles, second prophets, third teachers, then miracles, then gifts of healings, helps, administrations, and various kinds of tongues."
In other words, Scripture clearly says one thing, and Man says another. Therefore, one either adheres to cessationism or continuationism. There is no middle road.
What is the Word of God?
But to have this conversion, we must define what is the word of God? Is the Bible the word of God, or does it contain the word of God?
I’ll answer that question with another question: was King David’s rape of Bathsheba and the murder of her husband God’s idea, or was it David’s? Let’s assume it was David’s idea, but not God’s. That makes David’s actions, not the word of God – not God’s idea.
So then, we’re left with suggesting how the story is told, and the fact that the story is in the Bible is God’s idea – making it the word of God because it’s His STORY, but not His IDEA. Hence, the Bible both contains the Word of God and is the Word of God.
If we bring that logic forward, we’re left with this question: at what point did parts of Acts, 1 Corinthians, and Ephesians stop being “God’s IDEA” (aka, His WORD) and become just His STORY that He wanted to tell to make some here-to-now unknown point? And which other parts of the New Testament are just His “story bits” that we should now ignore, presuming them to not be God’s idea?
Finally, who is in charge of discerning and promulgating what should be sliced and diced out as authoritative?
