Gnosticism is an ever-present threat. Which is one reason why the dogma of the resurrection of the dead is under emphasized, and the immortal soul is thought of as the authentic human being and the body just a husk.
It's not just a husk since Jesus came back with a body. He ate to prove it, let Thomas touch him to prove it. Bodies are sacred when they are alive. When they are dead they are still reminders that God used and uses the machinery of the world to do his will. He made his own Son flesh and blood, not a blob of light. And he promised ressurection of the body.
