The Watchfulness Problem

"Watch therefore, for you do not know what day your Lord is coming" (Matthew 24:42)³⁰ only works as a moral summons if the day is genuinely unknown and genuinely still ahead of the person being told to watch. A day that has already occurred, and is simply unknown to the reader because they haven't been told the theology correctly, isn't the same kind of unknown Jesus is describing — it collapses "watch, because it could be any day" into "learn the right chronology," which is a different command doing different work on a life.

Every New Testament call to readiness — the thief in the night, the wise and foolish virgins, the servants left in charge — depends on live uncertainty for whoever is hearing it, not just for the first generation but for every generation the text keeps being read to. Full preterism can preserve the words. It has a harder time preserving what the words were built to do.

Seam Nine: The Commission Problem

The same structure that strains the Lord's Supper strains the Great Commission itself. Jesus closes the mandate to make disciples of all nations with an explicit temporal anchor: "And behold, I am with you always, to the end of the age" (Matthew 28:20).³¹ On full preterism, "the end of the age" names AD 70 — the close of the old covenant world. That produces the identical shape as Seam Six: a promise, and a mandate riding on that promise, both bounded by a terminus that, on this dating, arrived nineteen centuries ago. The church has never stopped sending, teaching, or claiming the ongoing presence the commission promises. The temporal marker attached to that presence and that mandate no longer points forward for anyone still carrying it out.

The honest full-preterist reply deserves to be stated, not waved off: the commission's reach — "all nations," "all creation under heaven" — was itself completed within the apostolic generation, pointing to Paul's own language at Colossians 1:6 and 1:23 and Romans 10:18,³² where the gospel is already described as having gone out to the whole world. On that reading, "to the end of the age" simply marks when that particular apostolic task closed, and everything the church has done since is a different, non-eschatological continuation, not evidence the promise's clock is still running.

That's a real answer, and it closes part of the gap. It doesn't close all of it. Even granting the first-generation reach of the gospel, the words of the commission still bind two things together — the promise of Christ's ongoing presence and the mandate to keep teaching everything He commanded — to a stated terminus. If that terminus passed in AD 70, the church has spent nineteen centuries repeating a promise and a mandate whose own attached horizon closed before any of those centuries began. Partial preterism doesn't inherit this problem for the same reason it doesn't inherit Seam Six's: the age in view remains the one still stretching ahead of everyone still living under the commission — which is exactly why the church has kept saying the words and meaning them, the same way it has kept administering the Supper and meaning that too.
