Hippolytus was talking here about the particular Gnostic heresy first started by the Naassenes.
That is clearly false. That Gnostic heresy first started by the Naassenes is the same ''Hydra'' in his entirety, alluded shortly after by Hyppolitus. Therefore it is not a ''particular'' Gnostic heresy, but it is the
entire Gnosticism derived from the Naassenism.
However, he did not indicate where ends the following discussion about the different aspects of this Gnostic heresy.
And why should he indicate the end of the discussion, when it is his
entire work ''Against Heresies'' meant to destroy any particular head of the Hydra represented by Naassenism ? The silence of Hyppolitus about the end of the discussion about the different aspects of this Gnostic heresy is decisively more
unexpected, if that Gnostic heresy was a
particular one (Bernard's view), and not the set of all the heresies derived chronologically and ''spiritually'' from the Naasseni.
Justinus did not have a serpent but:
You are totally correct in this point. Justinus is explicitly declared a particular
single head of the hydra provoked by Naassenism.
But since, altering the words and the names of the serpent, they wish that there should be many heads of the serpent, neither thus shall we fail thoroughly to refute them as they desire.
Hppolitus cares to confute the heretic Justinus because he is a particular head of the Hydra of Naassenism and consequently Hyppolitus will take the disturb of killing all the other heads of the same monster.
Who were the other heads of the same monster born from Naassenism?
To answer to this simple question, Bernard does this very big mistake:
However Hippolytus did not indicate Simon Magus featured a serpent or had Pagan legends similar to those who textually precede him in book V. Therefore it is a different heresy.
That is totally wrong. Hyppolitus says clearly that Simon is the chronological and spiritual successor of Justinus, therefore he is another head of the same monstruous hydra born from Naassenism.
Since, then, we have explained the attempts (at a system) of the pseudo-gnostic Justinus, it appears likewise expedient in the following books to elucidate the opinions put forward in heresies following (in the way of consequence upon the doctrines of Justinus), and to leave not a single one of these (speculators) [NOTA BENE: ''speculators'' WHO FOLLOW JUSTINUS] unrefuted. Our refutation will be accomplished by adducing the assertions made by them; such (at least of their statements) as are sufficient for making a public example (of these heretics). (And we shall attain our purpose), even though there should only be condemned the secret and ineffable (mysteries) practised amongst them, into which, silly mortals that they are, scarcely (even) with considerable labour are they initiated. Let us then see what also Simon affirms.
That ''also'' is clearly
inclusive, i.e.,
explicitly Simon is included among the
''speculators'' who follow Justinus, himself in turn a
particular head of the hydra born from Naassenism.
Furthermore Simon is said to have inspired (with Justinus) the (different) Gnostic heresy of Valentinus (and not others, such as the Naassenes)
That is partially correct. The correct sequence of actions is : Justinus inspires Simon (and he is his contemporary, being his
direct teacher), and Simon inspires Valentinus.
Note: In its recapitulation in book X, Hippolytus put Justinus textually after Valentinus: just to show, as I said before, that Hippolytus did not always put these heretics in chronological order.
In Book X of ''Against Heresies''
http://www.newadvent.org/fathers/050110.htm
I see the same chronological order of the Book V, with the ''Naasseni'' (and the other ''Serpent-derived'' heresies: Perathians, Sethians, etc) put explicitly
before Simon Magus. Then the evidence is very
great that,
for Hyppolitus, the Naasseni were the
first Gnostics
in absolute terms, before even of Justinus and Simon.
Chapter 4. Summary of the Opinions of Philosophers Continued.
Persuaded, then, that the principle of physiology is confessedly discovered to be encumbered with difficulties for all these philosophers, we ourselves also shall fearlessly declare concerning the examples of the truth, as to how they are, and as we have felt confident that they are. But we shall previously furnish an explanation, in the way of epitome, of the tenets of the heresiarchs, in order that, by our having set before our readers the tenets of all made well known by this (plan of treatment), we may exhibit the truth in a plain and familiar (form).
Chapter 5. The Naasseni.
But since it so appears expedient, let us begin first from the public worshippers of the serpent.
Hyppolitus finds ''expedient'' to mention first the Naasseni, and de facto it is very useful for him, to show that the hydra of the entire gnostic heresy is derived entirely from the ''Serpentists'' par excellence: the Naasseni. In order so to offer
as a single head of that hydra any possible
particular sect or teacher.
Simon is not said to have derived his theories from the Naassenes, Perathians, Sethians and Justinus, either here or in book VI.
Simon is mentioned after the Nasseni in both the books.
And in more Simon is
included between the ''speculators derived'', as Justinus and/or from Justinus himself, from the hydra of Naassenism.
Again:
Since, then, we have explained the attempts (at a system) of the pseudo-gnostic Justinus, it appears likewise expedient in the following books to elucidate the opinions put forward in heresies following (in the way of consequence upon the doctrines of Justinus), and to leave not a single one of these (speculators) [NOTA BENE: ''speculators'' WHO FOLLOW JUSTINUS] unrefuted. Our refutation will be accomplished by adducing the assertions made by them; such (at least of their statements) as are sufficient for making a public example (of these heretics). (And we shall attain our purpose), even though there should only be condemned the secret and ineffable (mysteries) practised amongst them, into which, silly mortals that they are, scarcely (even) with considerable labour are they initiated. Let us then see what also Simon affirms.
That does not mean these heretics did not have titles like "Christ", "Son of Man" with other links to the Christian Jesus and Christianity.
To have titles like ''Christ'' but not ''Jesus'' means to be pre-christian. According to prof Stevan Davies, the Odist of the
Odes of Salomon is pre-christian, because he talks about a suffering ''Christ'' but didn't mention never ''Jesus''.
The Naasseni were not only chronologically
before Simon (and all his contermporaries, from Justinus to Paul), but had also a hymn that mentions ''Jesus'' and not Gospel-derived, hence probably a pre-christian hymn confirming a pre-christian
(=100% mythical) Jesus.
