Although it may indeed be the last inspired canonical book, such an assertion is not only difficult if not impossible to prove but also cannot negate the equally strong assertion that certain inspired authorities, I mean under the direct guidance of God himself through the Holy Spirit, got together in a back room somewhere and with perhaps faulty copies of works already in circulation they used their collective "remembrance of all things" to correct, adjust, perfect, compile those now deficient copies until the final letter-perfect edition of all 27 books was complete, and then in the spirit of their Jewish upbringing, they chanted to one another in their spirits, "If this really be of God it will prevail, and if of men it will fail." And with that they thrust this onto the church, and people are still debating to this day the legitimacy of that authoritative but unseen TESTAMENT that was forced onto the church.
