Is prophecy the same category of thing as Scripture?
Question 4062
The cessationist and continuationist debate turns, at its heart, on a single exegetical decision: are prophecy and Scripture the same category of thing? If they are, then genuine prophecy today would mean adding to the Word of God — an obvious impossibility given that the canon is closed. But if prophecy and Scripture are distinct categories, the entire argument unravels. And Scripture itself, read carefully, insists that they are distinct.
What Scripture Actually Is
Scripture is not simply any word God has ever spoken. It is a specific and identifiable body of divinely inspired, written revelation — preserved, recognised by the community of God’s people, and given permanent binding authority for the church in all ages. The technical term for this quality is “canonical” — from the Greek kanon, meaning a rule or standard. What Scripture says does not merely inform; it binds. It is the permanent, written deposit of God’s revealed will, the court of final appeal for all matters of faith and practice.
This means that not every genuine word from God is Scripture. The category of Scripture is defined not just by divine origin but by divine intention — God’s purpose that particular words be preserved in written form, recognised by His people, and authoritative across all times and places. That is a specific kind of divine communication, and the Bible itself acknowledges that God has communicated in ways that fall outside this category.
What John Tells Us
John’s Gospel closes with a statement that is quietly devastating to the cessationist conflation of prophecy with Scripture. “Now Jesus did many other signs in the presence of the disciples, which are not written in this book” (John 20:30). And again: “there are also many other things that Jesus did. Were every one of them to be written, I suppose that the world itself could not contain the books that would be written” (John 21:25). Jesus spoke and acted continuously throughout His earthly ministry. Only a fraction of what He said and did is recorded in the Gospels. The rest — the conversations, the teachings, the encounters we will never read — were genuinely the words and works of the eternal Son of God. They were not Scripture, because they were not preserved and canonised. But they were real.
This matters because it demonstrates, from the life of Jesus Himself, that genuine divine communication and canonical Scripture are not coterminous. God speaks more than what is written. What is written is Scripture; what is not written may still have been genuinely from God. The two categories overlap but are not identical.
Agabus and the Post-Pentecost Church
The book of Acts reinforces this with concrete examples. Agabus appears twice in the narrative, exercising what can only be described as genuine predictive prophecy. In Acts 11:28, he predicts a great famine, which duly occurs. In Acts 21:10-11, he enacts a symbolic warning about Paul’s impending arrest, using language that echoes the Old Testament prophets. Neither of these prophecies became Scripture. Neither was treated as possessing canonical authority. But neither was dismissed as fraudulent — the church took both seriously as Spirit-prompted speech that proved accurate.
Agabus was not writing a new epistle. He was not claiming to add to the deposit of faith. He was speaking as a prophet within the life of the church, and his words were weighed on those terms. This is precisely the pattern Paul describes in 1 Corinthians 14:29 — “let two or three prophets speak, and let the others weigh what is said.” Weighing a prophetic word is not the same as receiving a new book of the Bible. The category of congregational discernment Paul calls for simply does not apply to Scripture; you do not weigh Isaiah’s prophecy against the witness of the congregation. The weighing process exists precisely because prophecy carries a different kind of authority — genuinely from the Spirit when it is authentic, but subject to testing rather than automatically binding.
Why the Conflation Is Harmful
When cessationists argue that genuine prophecy today would mean adding to Scripture, they are, in effect, elevating the authority of prophecy beyond what the New Testament itself claims for it. Paul never treats the prophets of 1 Corinthians 14 as though their words carry canonical weight. He treats them as people through whom the Spirit speaks in ways that must be weighed, tested, and submitted to the community’s discernment. The cessationist argument inadvertently grants to prophecy the very status it is trying to deny — it assumes that any genuine prophetic word must be Scripture-level revelation, and then concludes that such words cannot occur. But that is a category the New Testament itself never establishes.
The honest position is that Scripture is the closed, permanent, binding written Word of God — and that the Spirit may still move people to speak words that are genuinely prompted by Him, subject to congregational testing, and carrying no canonical authority whatsoever. These are not competing claims. They are different descriptions of different things.
So, now what?
Maintaining this distinction protects both the authority of Scripture and the openness to the Spirit’s ongoing work. Collapsing the two categories does damage in both directions — it either raises every prophetic utterance to an unwarranted level of authority, or it closes the door to the Spirit’s speaking altogether. What Scripture calls us to is neither. It calls us to receive the written Word as final and binding, to test prophetic speech against that Word, and to remain genuinely open to the Spirit’s ministry in the life of the church — not in spite of biblical authority, but because of it.
