Chapter XVIII of Authors of the Gospels addresses this:
When the evidence provided by the ancient historians is re-examined, in the light of the Clementine tradition, we find many problems faced by scripture scholars may be resolved. My suggestions are given below.
- Two Editions of Mark
Clement of Alexandria tells us: “The audience, which was numerous, begged Mark …to write down the things he [Peter] had said. And he did so …”. Mark, as Peter’s secretary, would have had a team of scribes. So he would have been able to quickly publish this short record of Peter’s words. We are told that Peter showed little interest but, from another book by Clement, we know that when Peter became aware of its favourable reception, he approved it for use in the churches.
This indicates that Mark’s short Gospel was published in two editions – an unauthorized informal one and a second endorsed by Peter for use in the churches. Clement informs us that Mark issued the words of Peter while Peter was still alive, yet Irenaeus says that Mark published after the death of Peter. This again points to there having been two editions.
Again, this kinda reminds me of the controversial
Secret Gospel of Mark, fragments of which are found in a purported letter by Clement of Alexandria to a certain Theodoros.
- From the letters of the most holy Clement, of the Stromata.
To Theodoros.
You did well in silencing the unspeakable teachings of the
Carpocratians, for these are the “
wandering stars” (Jude 1:13) that had been prophesied, who wander from the narrow road of the commandments into an endless abyss, deceived by the fleshly and bodily sins. For having been puffed up of their knowledge - as they say - “
of the depths of Satan,” (Revelation 2:24) they do not know that they are throwing themselves down into “
the blackness of darkness” (Jude 1:13) of lies. And having boasted that they are free, they have become bondservants of base desires. Such are to be opposed in all ways and altogether. Because even if they say something true, still the lover of the truth should not agree with them, for not all true things are truth, nor should that truth which merely seems true according to human opinions be preferred to the true truth, that according to the faith.
Now, concerning their babblings about the “
God-breathed” (cf. 2 Timothy 3:16)
Gospel according to Mark, some are wholly lies, while others, even if partly true, nevertheless are not reported truly. For the true things being mixed with inventions are debased so that, as the saying goes, “
even the salt has become tasteless” (cf. Matthew 5:13).
As for Mark, then, during Peter’s stay in Rome he wrote an account of the acts of the Lord, not, however, declaring all of them, nor yet hinting at the mystical ones, but picking the things he thought most useful for increasing the faith of those who were being catechized. Then when Peter was martyred, Mark came to Alexandria, bringing both his own knowledge and those of Peter, from which he transferred to his first book the things suitable about knowledge for those who are making progress. Thus he arranged a more spiritual gospel for the use of those who were being perfected.
Nevertheless, he did not reveal the things which are not to be uttered. He did not write out the hierophantic teaching of the Lord, but to the stories already written he added yet others, and, moreover, brought in certain sayings of which he knew the interpretation would, as a mystagogue, lead the hearers into the
adyton of the truth which is veiled seven times. Thus he prepared them - in my opinion - not ungrudgingly or unguardedly. And dying, he left his writing to the church in Alexandria, where even now it is still extremely carefully guarded, being read only to those who are being initiated into the great mysteries.
However, since the polluted demons are always devising destruction for the race of man, Carpocrates, taught by them and using their deceptive arts, so enslaved a certain presbyter of the church in Alexandria that he got from him a copy of the mystical gospel, which he both interpreted according to his blasphemous and fleshly authority and, moreover, defiled, mixing with the most spotless and holy words the most shameless lies. From this mixture is derived the teaching of the Carpocratians.
To them, therefore - as I said above - one must never give way. Also, when they put forward their falsifications, one should not concede that the mystical gospel is by Mark, but should deny it even on oath, for not all truth are to be said to everyone. For this reason, the wisdom of God through Solomon gives a message, “
Answer a fool from his folly” (cf. Proverbs 26:5), teaching that from those whose minds are blinded the light of the truth should be concealed. Again it says, “
From him who has not, it will be taken away,” and, “
Let the fool go in darkness.”
But we are the “
sons of light” (John 12:36) who have been illuminated by “
the dawn from on high” (Luke 1:78) of the Spirit of the Lord. “
Where the Spirit of the Lord is,” it says, “
there is freedom” (2 Corinthians 3:17), for “
to the pure, all things are pure” (Titus 1:15). Therefore to you I will not hesitate to answer the questions you have asked, refuting the falsifications by the very words of the gospel. For example, after “
They were in the road, going up to Jerusalem,” and what follows, until “
After three days He will arise,” (Mark 10:32-34) it takes up according to the text:
