There are also parallels between his gospel and his epistles, which were final warnings to Jews before the “decommissioning of the office of Jew.” John puts Jesus’ cleansing of the Temple out of chronological sequence, near the beginning, to set the theme for his gospel — the cleansing of the Temple!

Other than this, there’s structural evidence from the Old Testament that the entire Bible should be finished before the end of Temple worship, plus the “sealing up” of vision and prophecy in Daniel. After AD70 there was no longer any testifying “head,” only body and Spirit.
