> In my opinion, what gives the works of the Church Fathers any authority is their relationships with the apostles themselves.
Except that there’s no good evidence for this. The claims you cite are so typical of the human tendency to seek links and connections in the scanty information we have that they can in my view be safely dismissed as secondary inventions. If we find jewels at the site of Troy, obviously they belonged to Priamus. If we find a golden mask from Mycenaean Greece, whose mask could it possibly have been but Agamemnon’s? And if the New Testament doesn’t name the man who fled naked from the garden of Gethsemane, or the little child Jesus took up in his arms, it stands to reason they must have been well-attested people from elsewhere like, respectively, John Mark or Ignatius.
No. Such easily-to-invent traditions need to be rejected unless the evidence for them is superb. The correct answer is clearly that we simply don’t know, and neither did anyone else. Your sources are late (Theodore of Cyrrhus ridiculously so but even Irenaeus is too late to be interesting). As for your claim that Irenaeus was taught by Polycarp, I thought all Irenaeus said on the subject was
> But Polycarp also was not only instructed by apostles, and conversed with many who had seen Christ, but was also, by apostles in Asia, appointed bishop of the Church in Smyrna, whom I also saw in my early youth, for he tarried [on earth] a very long time, and, when a very old man, gloriously and most nobly suffering martyrdom, departed this life, having always taught the things which he had learned from the apostles, and which the Church has handed down, and which alone are true.
Which isn’t much and certainly doesn’t imply he received instruction from him.
> It seems that your point is the historicity of the Judas betrayal, about which we could certainly talk. Maybe it's not so tangential.
My view on the historicity of Judas’ betrayal is one I’m quite willing to debate. However, in our lengthy past debate we failed to agree on certain crucial matters of methodology which, I fear, may well throw a spanner into the works yet again. Still, here goes.
1. The betrayal story displays two very significant contradictions: the way Judas died and the way the field was named. IIRC you don’t think these contradictions are real. Suffice it to say that in other ancient texts no attempt would be made to reconcile contradictions as blatant as these, so I’m going to stick to secular methodology for the moment and go by that assumption: granted that these contradictions are real, that tells us two things about the story. Firstly, that the early Christian community was not sure how Judas died, which, not exactly being a trivial detail, you’d kind of expect them to know if the story was real; and secondly, that the early Christian community was willing to fabricate elements in the story to explain local toponymy. Both of these render the whole tale intensely fishy.
2. The betrayal story is ad hoc. There is no immediately obvious reason why the Jewish leaders would need a close follower to identify a popular preacher. Not a knock-down argument, but a sound cumulative argument taken in combination with the others.
3. The betrayal story too conveniently fulfils the “30 pieces of silver” prophecy. We know from elsewhere that the early Christians were prepared to make stuff up to get Jesus to fulfil prophecies, as with the Nazarene prophecy at the end of Matthew 2 (again, you may not agree with that but bear with me for a cumulative case), so the convenience of the Judas story in this regard decreases the likelihood that it is true.
4. The betrayal story assumes that the rest of the passion narrative is accurate. I see no reason to assume any Jewish involvement at all in Jesus’ death. The more parsimonious explanation is that the Romans executed him in their customary knee-jerk reaction to potential trouble-makers in ancient Palestine. This makes the Judas story redundant.
Alone these arguments can be questioned, but the combination I regard as very powerful.
All this is why, IMO, the Pauline evidence really matters. A reference to the betrayal by Paul would require a substantial revision to my current view of early Christianity.
> So I'm trying to get your point. Help me to understand. To what does ἐν τῇ νυκτὶ ᾗ παρεδίδετο (on the night he was παρεδίδετο) refer, the night when bread was broken and wine was drank (drunk? drunken?) after supper?
I’d say “drunk”, but that may be BrE : )
Why does παρεδίδετο have to mean handed over by human agency? Why not by God for the substitutionary atonement he was about to undertake? (Sorry for the vague references, my knowledge of Paul’s view on Atonement is sketchy, I have the bad habit of skipping the boring theology bits)
> what does "the holy vine of Thy son David" mean? (Didache 9)
I assume the imagery is comparable to that in John 15. It would refer to the unity of the Church, which fits with the rest of the text.
> how was this "vine" made known through Jesus?
Risky to speculate without further knowledge of the Didache’s theology, but I doubt if it’s the Atonement. There’s no reason to make the references to a specific historical context so oblique. This would only serve to highlight the absence of any real references.
If I could speculate I’d say it had something to do with the eschatological Kingdom of God being revealed through Jesus.
> how was the broken bread made known through Jesus?
It doesn’t say that at all, which again, kind of highlights the absence of references to Jesus' death.
