Carpocrates of Alexandria (Greek: Καρποκράτης ήταν αλεξανδρινός) was the founder of an early Gnostic sect from the first half of the 2nd century, known as Carpocratians. As with many Gnostic sects, one knows of the Carpocratians only through the writings of the Church Fathers, principally Irenaeus of Lyons and Clement of Alexandria. As these writers strongly opposed Gnostic doctrine, there is a question of negative bias when using this source. While the various references to the Carpocratians differ in some details, they agree as to the libertinism of the sect, a charge commonly levied by pagans against Christians and conversely by Christians against pagans and heretics.
The earliest and most vivid account of Carpocrates and his followers comes from Irenaeus (died 202) in his Against Heresies including an account of the theology and practice of the sect.
They believe, he writes, that Jesus was not divine; but because his soul was "steadfast and pure", he "remembered those things which he had witnessed within the sphere of the unbegotten God" (similar to Plato's concept of Anamnesis). Because of this, Jesus was able to free himself from the material powers (what other Gnostics call Archons, the Demiurge, etc.). Carpocratians believed they themselves could transcend the material realm, and therefore were no longer bound by Mosaic law, which was based on the material powers, or by any other morality, which, they held, was mere human opinion. Irenaeus offers this belief as an explanation of their licentious behaviour.
Irenaeus then goes on to provide his further, slightly different, explanation. The followers of Carpocrates, he says, believed that in order to leave this world, one's imprisoned eternal soul must pass through every possible condition of earthly life. Moreover, it is possible to do this within one lifetime. As a result, the Carpocratians did "all those things which we dare not either speak or hear of" so that when they died, they would not be compelled to incarnate again but would return to God.
