Docetism

Docetism was a Gnostic heresy, that was condemned by the  Early Church, with several variations concerning the nature of Christ. Generally, it taught that Jesus only appeared to have a body, that he was not really incarnate, (Greek, "dokeo" = "to seem"). This error developed out of the dualistic philosophy which viewed matter as inherently evil, that God could not be associated with matter, and that God, being perfect and infinite, could not suffer.
