The Gospels · disputed — letter attributed to Clement of Alexandria (c. 200 CE) if authentic; possibly a modern composition
The Secret Gospel of Mark
The Secret Gospel of Mark survives only as two short excerpts quoted in a letter attributed to Clement of Alexandria, discovered by Morton Smith at the Mar Saba monastery in 1958 — a manuscript later lost, photographs aside. The letter describes a 'more spiritual' edition of Mark kept at Alexandria and quotes its most famous scene: Jesus raising a young man from a tomb and teaching him 'the mystery of the kingdom.' Its authenticity is one of the great unresolved disputes in the field, and we label it accordingly: disputed.

In 1958 the historian Morton Smith, cataloguing the library of the Mar Saba monastery in the Judean desert, photographed a Greek letter copied onto the endpapers of a seventeenth-century book. The letter presents itself as Clement of Alexandria (c. 150–215 CE) writing to one Theodore about a secret, 'more spiritual' Gospel of Mark used in Alexandria — and it quotes two passages.
In the first, placed after Mark 10:34, Jesus raises a young man from a tomb at his sister's plea; the youth, loving him, comes to him after six days wearing a linen cloth over his naked body and stays the night to be taught 'the mystery of the kingdom of God.' The second is a single line about the sister and Salome at Jericho. Clement's letter insists the Carpocratians — the libertine gnostic sect — had corrupted this text, and instructs Theodore to deny its existence even under oath.
Whether any of this is ancient is fiercely disputed. The physical manuscript was transferred to the Jerusalem Patriarchate's library and has not been produced since; only Smith's photographs remain. Some scholars (Stephen Carlson, Peter Jeffery) argue the letter is a twentieth-century hoax — possibly Smith's own; others (Scott Brown, and many Clement specialists who find the style convincingly Clementine) defend its authenticity as a genuine Clement letter quoting a real second-century Alexandrian edition of Mark. No consensus exists.
Per this library's standards, we publish it labeled exactly as what it is: a disputed text, with its provenance stated plainly. The translation below is Samuel Zinner's, proofread by Mark M. Mattison, in the public domain.
From the epistles of the most holy Clement, of the Stromateis (Miscellanies). To Theodore.
The Doctrines of the Carpocratians
You did well, silencing the unmentionable doctrines of the Carpocratians. For these are the prophesied stars straying from the narrow path of the commandments into a bottomless abyss of fleshly and bodily transgressions. For being inflated as to “knowledge,” as they say, “of the deep things of Satan,” they overlook that they cast themselves into the deepest gloom of falsehood, and bragging they are free, they have become slaves of servile lusts. These, therefore, must be opposed in each and every way. For, even if they say something true, nevertheless, one who loves truth must not agree with them. For not everything actual is the truth, nor is what appears to be true according to human opinion to be preferred over the real truth according to the faith.
So of the chatter about the divinely inspired Gospel according to Mark, some things are completely false, and even if others contain some true things, they nevertheless have not been transmitted truly. For true things when commingled with concoctions become counterfeits, so that, according to the saying, “Even salt loses its taste.” Then regarding Mark, during Peter’s sojourn in Rome, he wrote a narrative of the Lord’s deeds, but not recording everything, nor especially indicating what is mystical, but selecting what he thought most useful for the increase of the catechumens’ faith.
When, however, Peter was martyred, Mark fled to Alexandria, bringing both his own and Peter’s drafts, from which he copied into his first book the things fitting for advancement in knowledge, preparing a more spiritual gospel for the use of the mature. Similarly, not once did he publish the secret things, nor write the hierophantic doctrine of the Lord, but arranged the previously mentioned deeds as well as others. Furthermore, he introduced certain sayings, the exegesis of which he had knowledge, to initiate the hearers into the holy of holies of the truth veiled seven times. Therefore, in this way he prepared in advance, not grudgingly or carelessly, as it seems to me, and when he died he left behind his writing to the church in Alexandria, where it is even now kept exceedingly well guarded, being recited solely to those who those initiated into the greater mysteries.
However, as the blood-stained demons are ever scheming the damnation of the human race, Carpocrates, instructed by them and employing deceitful skills, enslaved in this manner a certain presbyter of the church in Alexandria so that from him he obtained a copy of the mystical gospel, and which he interpreted according to his blasphemous and fleshly opinion. What is more, he polluted the undefiled and sacred sayings by commingling them with the most revolting lies. From this commingling is derived the doctrine of the Carpocratians. To these, then, even as I have reported earlier, one must never yield nor admit when they make false allegations, that the mystical gospel is by Mark, but should even deny it on oath. For not to everyone should everything that is true be told.
On account of this, the wisdom of God through Solomon commands, “Answer the fool from his foolishness,” teaching us that it is necessary that from darkened minds the light of truth be hidden. For example, it says, “From the one who has not, it will be taken away,” and, “Let the fool walk in darkness.” We, however, are sons of light, having been illuminated from above by the dawn of the spirit of the Lord. “But where the spirit of the Lord is,” it says, “there is freedom.” “For to the pure, all things are pure.”

So I will not refrain from answering the things you asked, exposing the false reports with the same sayings of the gospel. Naturally, after the (words) “they were on the way, going up to Jerusalem,” and the following things until, “After three days he will rise again,” thus it reads word for word:
And they entered into Bethany and there was a woman there whose brother had died. And she came and prostrated to Jesus, and said to him, ‘Son of David, have mercy on me.’ The disciples, however, rebuked her.
And growing angry, Jesus went away with her into the garden where the tomb was, and suddenly there was heard a loud sound from the tomb, and Jesus drew near and rolled away the stone from the door of the tomb, and entering immediately where the youth was, he stretched out his hand and raised him up and grabbed hold of his hand, but seeing him, the youth loved him, and started to implore him that he could be with him.
And coming out of the tomb, he entered the house of the youth, for he was wealthy. And after six days, Jesus ordered him, and when evening came, the youth approached him naked, being covered with only a robe. And he stayed with him that night. For Jesus taught him the mystery of the kingdom of God. From there, he rose and returned to the other side of the Jordan.
And although these (words) follow the (words), “and James and John approached him,” and the whole pericope, by contrast, the (words), “naked on naked,” and the other things you wrote about are not found. After, however, the (words), “he entered into Jericho,” it introduces only, “and there were the sister of the youth whom Jesus loved, and his mother and Salome, and Jesus did not receive them.”
The many other things you wrote, however, appear to be, and are, false reports. Certainly indeed, the true exegesis, in accord with the true philosophy [. . .]

Common questions
Is the Secret Gospel of Mark real?
Genuinely unresolved. The manuscript — a Greek letter attributed to Clement of Alexandria, copied into a 1646 book — was photographed in 1958 and has since disappeared from scholarly access. Specialists divide between reading it as an authentic Clement letter quoting a real Alexandrian edition of Mark and as a modern forgery. We label it disputed and let you read what exists.
What does the Secret Gospel of Mark actually say?
Two excerpts survive, quoted in the letter: Jesus raising a young man from a tomb who then comes to him by night, linen-clad, to be taught 'the mystery of the kingdom of God' — a scene resembling both Lazarus and Mark's own fleeing youth in Gethsemane — and one line mentioning the youth's sister and Salome at Jericho.
Did Morton Smith forge the Secret Gospel of Mark?
It has never been proven either way. The forgery case rests on the manuscript's convenient disappearance, claimed anachronisms, and Smith's own interests; the defense notes the letter's deep fit with Clement's style and vocabulary, argued by scholars who knew the corpus better than Smith plausibly could. Every reconstruction of this text's history requires believing something remarkable.
Why include a disputed text in the library?
Because honesty beats omission: the text is famous, endlessly discussed, and usually encountered through partisans of one verdict. We serve the actual excerpts with the dispute stated plainly — which is exactly how a library should handle an unresolved question.
