Hylemorphism, rigid designators, and the disembodied 'Jesus': a call for clarification

Many in the Christian tradition affirm two things: (1) that Jesus Christ descended to Hades/Limbus Patrum on Holy Saturday and (2) that the human nature of Jesus is a hylemorphic compound, the unity of a human soul and prime matter. I argue that (1) and (2) are incompatible; for the name 'Jesus', 'Christ', and 'Jesus Christ' rigidly designates a human being. But, given a certain view of hylemorphism, the human being, Jesus, ceased to exist in the time between his death and resurrection. So, Jesus did not descend to Hades/Limbus Patrum, even if God the Son did.
