What I am wondering about now is whether the second edition of Hegesippus (assuming that such a text existed) changed the underlying focus of the original Outlines. Now it wasn't that one heretic 'Marcellina' came to Rome during the reign of Anicetus but now Marcion came to Rome during Anicetus's reign and I wonder, whether other heretics were also added to that list so as to make the overall point of Hegesippus's 'witness' agree with Adversus Haereses.
Why do I think that? Because there appears to be repeated chronological allusion in Adversus Haereses to specific bishops of the Roman Church whenever heresies are mentioned. For instance Cerdo:
and again in Book Three immediately following the use of the succession list in chapter 3:Cerdo was one who took his system from the followers of Simon, and came to live at Rome in the time of Hyginus, who held the ninth place in the episcopal succession from the apostles downwards. [AH 1.27.1]
Notice the explicit reference to the ninth and tenth place in the succession list. Notice when Marcellina is mentioned in Book One Hegesippus's original statement (reconstructed by Lawlor from Epiphanius) that the Gnostics started with her appearance is now softened:If any one were to preach to these men the inventions of the heretics, speaking to them in their own language, they would at once stop their ears, and flee as far off as possible, not enduring even to listen to the blasphemous address. Thus, by means of that ancient tradition of the apostles, they do not suffer their mind to conceive anything of the [doctrines suggested by the] portentous language of these teachers, among whom neither Church nor doctrine has ever been established. For, prior to Valentinus, those who follow Valentinus had no existence; nor did those from Marcion exist before Marcion; nor, in short, had any of those malignant-minded people, whom I have above enumerated, any being previous to the initiators and inventors of their perversity. For Valentinus came to Rome in the time of Hyginus, flourished under Pius, and remained until Anicetus. Cerdon, too, Marcion's predecessor, himself arrived in the time of Hyginus, who was the ninth bishop. Coming frequently into the Church, and making public confession, he thus remained, one time teaching in secret, and then again making public confession; but at last, having been denounced for corrupt teaching, he was excommunicated from the assembly of the brethren. Marcion, then, succeeding him, flourished under Anicetus, who held the tenth place of the episcopate. But the rest, who are called Gnostics [AH 4.2]
In Hegesippus it is clearly stated that the Gnostics began with Marcellina's arrival in Rome which is flatly contradicted by what Irenaeus says in Book Three. He says in no uncertain terms "[f]or, prior to Valentinus, those who follow Valentinus had no existence; nor did those from Marcion exist before Marcion; nor, in short, had any of those malignant-minded people, whom I have above enumerated, any being previous to the initiators and inventors of their perversity." Now it might be argued that Irenaeus has in mind specific features of the heresies associated with Valentinus and Marcion distinguished them in such a way that he was justified in saying that prior to Valentinus there were no Valentinians.From among these also arose Marcellina, who came to Rome under Anicetus, and, holding these doctrines, she led multitudes astray. They style themselves Gnostics.
But there is a problem here because earlier in Book 1 he says quite explicitly "the first of them, Valentinus, who adapted the principles of the heresy called "Gnostic" to the peculiar character of his own school, taught as follows ..." Here there is a pre-existent 'gnostic' heresy but that first gnostic sect is not Marcellina or Carpocratians who - it is said - only 'style' themselves Gnostics. No it would seem that Irenaeus has tried to assimilate a claim possibly from Justin's Syntagma that Simon was the originator of the Gnostics - cf. 1.29.1 "Besides those, however, among these heretics who are Simonians, and of whom we have already spoken, a multitude of Gnostics have sprung up ..."
My sense is then that there is no evidence from Irenaeus's or Eusebius's use of the second edition of Hegesippus that Marcellina had any influence over the gnostics in Rome whatsoever. She might as well have been removed from the succession list and - as I now suggest - the names Cerdo and Valentinus were added before the time Hegesippus claimed Marcellina introduced the 'Gnostics' to Rome:
It would seem then that Irenaeus's war with the Valentinians - a combative spirit that pervades Adversus Haereses - caused him to alter the contents of Hegesippus's Outlines.In Anicetus' time then, as I said, the Marcellina I have spoken of appeared at Rome spewing forth the corruption of Carpocrates' teaching, and corrupted and destroyed many there. And that made a beginning of the so-called Gnostics.
My point is that you can't have developed Adversus Haereses and its argument that Valentinus preceded Marcellina in Rome and preceded her identification of being 'gnostic' if - as the original text of Hegesippus made explicit - Marcellina's visit under Anicetus "made a beginning of the so-called Gnostics" in Rome. Something had to give and I think the second edition of the Outlines made significant changes to the underlying 'history' of the early Church in order to make it accord with Irenaeus's efforts against the Valentinians.
The change from 'Marcellina' to Marcion wasn't part of some plot against the Marcionites. 'Marcion' was something of an afterthought (and the additions to Justin to further 'prove' his existence'). Valentinus had to be proved to be the first 'gnostic' and the first heretic in Rome condemned by Hegesippus. Jerome tries to reconcile the two accounts by effectively saying that Marcellina was the first Marcionite (or perhaps more exactly that the first Marcionite missionary to Rome was female = Marcellina). But the Marcion/Marcellina 'switch' casts serious doubts on the contents of second edition of the Outlines and I believe the existence of Marcion and the Marcionites. There was certainly a tradition identified as 'Marcionite' but as Bauer notes they themselves simply called themselves 'Christians' and it is also odd that in the Acts of Archelaus the dominant orthodoxy in the Marcionite region (Osroene and vicinity) mention a prominent leader-figure named 'Marcellus' as a leader from Rome who founded churches and hospices etc. A group named after a woman named after a woman named Marcellina or a man named Marcellus would likely have the same or similar name I think.
