Origen, of course as many know, was a heretic. However it's interesting to note what books he accepted in the NEW TESTAMENT, given that he's being presented here as a witness for a theory held by someone who says that we ALL agree on the NT.
"At other times Origen, accepts as Christian evidence any material he finds convincing or appealing, even designating on occasion these writings as 'divinely inspired':
Gospel of Peter
Gospel of the Hebrews
Acts of Paul
I Clement
Epistle of Barnabas
Didache
Shepherd of Hermas"
The Development of the Canon of the New Testament - Origen
Origen's 'witness' is misrepresented because he doesn't agree with the case being presented.
Not at all surprising- StandingUp picks from both the pantry and the refuse bin, and excerpts capriciously and with great license.
His case thus far has the appearance of a letter assembled by a serial killer or a beast stitched together in Ingolstadt, Bavaria.
There is a practice among some to proof text, to pick and chose among the scriptures, excerpting and quoting out of context, with the express purpose of defending or creating unique and/or perverse doctrines.
And then there is the issue of canon. We cannot arrive at it by (excuse a third metaphor) reading the tea leaves of history. To say that Christ or Paul did not mention thus and such, therefore they are null and void is a laughable fallacy (argument from silence). To insist on maintaining the veracity of such a claim after it has been shown to be fallacious is a worse offense, and is a violation of one of the Ten.
We know that Saint Jerome did not care for certain books. That's cool, he's one of the people on the panel, as it were. How is it that SU cites him, but dismisses the remainder of the panel? What gives him the right- did StandingUp have a seat at this lauded table? Yet he will say that the opinions of others are null and void because they support doctrines he, Rev StandingUp, rejects. 1000 blessings to the first one to identify THAT logical fallacy.
Canon is a difficult subject. It TRULY is an issue of continuity within the faith community, which is a bit dicey. Clearly there are some subtle differences between OO, EO, and RC. I understand the impetus to throw out that which is not consensus, but I'm not certain that the Reformers earned a right to sit at that panel.
Among Protestants, I find SummaScriptura's position (that which has been consistently employed) to be the most sensible and logically consistent.
