Mary and Jesus up to the mountain, drinking semen, Bacchic mystery. Takes her from his "rib" (pleurās (Πλευρᾶς) from his side, not literal rib - just like Adam takes eve from his side in Genesis), forced to be the receptacle of the hyma from Jesus. Makes sense why they called her a prostitute. As a part of salvation. (Epiphanius is criticising heretic sects, in this case the gnostics).
Epiphanius of Salamis, Panarion 26.8
8. And their books are many. For in some Questions of Mary certain things are set forth; others are attributed to the previously mentioned Ialdabaōth; and many books are also ascribed to the name of Sēth. They also speak of other Revelations of Adam, and they have dared to compose different gospels in the name of the disciples. And they are not ashamed to say that our lord of the realm Jesus Christ himself revealed this disgraceful act.
For in the so-called Great Questions of Mary (for they have also fabricated Lesser ones), they assert that he reveals it to her — having taken her up into the mountain, prayed, and brought a woman that was by his side, and began to have intercourse with her. And thus — supposedly — having shared his emission with her, he showed her and said: “This must be done so that we may live.”
And when Mary was disturbed and fell to the ground, he raised her up again, and said to her: “Why did you doubt, you of little faith?” And they say this is what was spoken in the Gospel: “If I told you earthly things and you do not believe, how will you believe if I tell you heavenly things?” and also: “When you see the son of man ascending to where he was before” — that is, the emission being received back to the place from which it came forth.
And they say that the saying “Unless you eat my flesh and drink my blood”, and the disciples being troubled and saying “Who can listen to this?” — was spoken about that act of obscenity. Therefore they were disturbed and withdrew backwards, for, they say, they had not yet been confirmed in the fullness (Plerōma).
And as for David’s saying: “He shall be like a tree planted by streams of water, which will yield its fruit in its season” — they say that this refers to the obscene act of the man. “By the stream of water,” and “will yield its fruit” — they interpret as the emission of pleasure; and “its leaf shall not fall” — meaning, they say, “We do not let it fall to the ground, but we ourselves eat it.”
