Parallels Between Clement's Initiation in Alexandria by Barnabas in the Homilies and Secret Mark

Clementine Homilies (Clement and Barnabas in Alexandria after hearing an unnamed preacher in Rome): I left all my affairs as they were, and sped to Portus; and coming to the harbour, and being taken on board a ship, I was borne by adverse winds to Alexandria instead of Judæa ... And when I said that I wished I could meet with some one of those who had seen Him, they immediately brought me to one, saying, “There is one here who not only is acquainted with Him, but is also of that country, a Hebrew, by name Barnabas, who says that he himself is one of His disciples; and hereabouts he resides, and readily announces to those who will the terms of His promise.” Then I went with them; and when I came, I stood listening to his words with the crowd that stood round him; and I perceived that he was speaking the truth not with dialectic art, but was setting forth simply and without preparation what he had heard and seen the manifested Son of God do and say.

I took Barnabas by the hand, and by force conducted him, against his will, to my lodging, and constrained him to remain there ... And having spent several days, and instructed me briefly in the true doctrine he said that he should hasten into Judæa 

Clementine Recognitions (Clement and in Rome):

But as the day was declining to evening, I laid hold of Barnabas by the right hand, and led him away, although reluctantly, to my house; and there I made him remain, lest perchance any one of the rude rabble should lay hands upon him. While we were thus placed in contact for a few days, I gladly heard him discoursing the word of truth yet he hastened his departure, saying that he must by all means celebrate at Judæa 

Secret Mark:

he [Jesus] stretched forth his hand and raised him, seizing his hand. But the youth, looking upon him, loved him and began to beseech him that he might be with him. And going out of the tomb, they came into the house of the youth, for he was rich. And after six days Jesus told him what to do, and in the evening the youth comes to him, wearing a linen cloth over his naked body. And he remained with him that night, for Jesus taught him the mystery of the Kingdom of God. And thence, arising, he returned to the other side of the Jordan [to Judea]
