When they have had intercourse out of the passion of fornication, then, holding up their own blasphemy before heaven, the woman and the man take the man’s emission in their own hands, and stand there looking up towards heaven. And while they have uncleanness in their hands, they profess to pray… “We offer you this gift, the body of Christ.” And so they eat it, partaking of their own shame and saying, “This is the body of Christ, and this is the Passover.” Similarly with the woman’s emission at her period; they collect the menstrual blood wich is unclean, take it and eat it together, and say “This is the blood of Christ.”

Epiphanius, Panarion,  (description of the “Stratiotici” heretics)

“Truth is like ignorance. When it is hidden, it rests in itself. But when it is revealed and recognized, it is praised.” – The Gospel of Philip
