[ETA:
This post has been heavily edited; much of it was simply irrelevant to the Secret Mark debate. I am greatly relieved by this. Of the rest, I have tightened the focus on the fact that the letter's author did not need a modern source for its account of the Carpocratians. I will leave it at that for now.]
In Peter Jeffery's response to Scott Brown (the "official" version, rejected by RBL but
self-published on Jeffery's website), Jeffery protests that Clement's known writings show no awareness of homosexuality among the Carpocratians:
[T]he vice Clement ascribed to the Carpocratians was heterosexual wife-swapping, the sharing of wives like common property as in Plato's Republic (Strom. 3.5-10, 3.25.5, 3.54.1). Whoever was trying to set up a confrontation between Clement and homosexuality, in other words, picked the wrong heretical group. Where did the Mar Saba "Clement" get the idea that the Carpocratians were particularly interested in naked men?
Jeffery suggests that Smith got the idea from Gershom Scholem's studies of the Sabbateans:
The answer: from Smith's teacher Gershom Scholem, who compared the Carpocratians to certain antinomian sects descended from the seventeenth century Jewish heresy of Sabbatai Zevi. Scholem's opinion that these sects believed in "Redemption through Sin" appears to explain Smith's statement that "Carpocrates was said to have taught that sin was a means of salvation."
But, first of all, we have evidence from Irenaeus, closely pre-dating Clement, that Carpocratians did have a "redemption through sin" theology (
Against Heresies, 1.25.4: "They deem it necessary, therefore, that by means of transmigration from body to body, souls should have experience of every kind of life as well as every kind of action"). Furthermore, we have evidence in
Stromata that the Carpocratians and the group Clement calls “the Opponents” held a similar theology (
Strom. 3.34.3-4: "Since it is the [demiurge] who said 'You shall not commit adultery,' we should, they say, commit adultery so as to annul his order). All this is similar to Irenaeus’ description of the Carpocratian teachings concering the “adversary”:
They also declare the "adversary" is one of those angels who are in the world, whom they call the Devil, maintaining that he was formed for this purpose, that he might lead those souls which have perished from the world to the Supreme Ruler....Again, they interpret these expressions, "You shall not go out thence until you pay the very last farthing," as meaning that no one can escape from the power of those angels who made the world, but that he must pass from body to body, until he has experience of every kind of action which can be practised in this world, and when nothing is longer wanting to him, then his liberated soul should soar upwards to that God who is above the angels, the makers of the world. (Against Heresies, 1.25.4)
Notice also that in defining each group, both Clement’s Opponents and Irenaeus’ Carpocratians refer to Mt 5:25-26, quoted in
Against Heresies, 1.25.4 above (and again later in the same passage), as well as in
Strom. 3.36.1, in reference to the Opponents. Irenaeus also writes that the Carpocratians “declare they have in their power all things which are irreligious and impious, and are at liberty to practise them”, and if they also “lead a licentious life” (
Against Heresies 1.25.3).
Nevertheless, it would be a mistake to think that
To Theodore attributes homosexuality to the Carpocratians. True, the letter opens with a denunciation of the Carpocratians as those who wander “into a boundless abyss of the carnal and bodily sins” and goes on to describe a man who is said to love Jesus upon seeing him, and who begs to “be with” Jesus. But there is certainly nothing the text of Secret Mark that attributes homosexual behavior to either Jesus or the man.
We also know that the Carpocratian text went on to add something about “naked man with naked man”, but that's all. Nowhere in any of this do we have persuasive evidence of Carpocratian homosexuality. Indeed, the reference to male nudity might be entirely non-sexual, as we know that early Christian baptismal rituals, for example, involved nudity. The only thing the letter accuses the Carpocratians of is “carnal and bodily sins”--and in this it is quite consistent both with what Clement says of them in
Stromata and with what Irenaeus says of them in
Against Heresies. The letter's account of the Carpocratians provides no evidence for forgery.
