[Bayard]

Didn't Jesus die? It said he "breathed his last" -- does the commending of his spirit into the Father's hands denote a separation from his human nature? Or did his body vanish from the cross?

You're confusing nature with only the physical body. Jesus had a Human Will in union with His Divine Will.

When we die we are separated from our bodies, but though the flesh dies the nature of our humanity only experiences death which is separation of soul and body. The Humanity undergoes death, But We will also be resurrected in the flesh Just as Jesus restored his body in the resurrection.

At no time even in the tomb, was the death of Jesus a separation from his humanity.

At no time even in the tomb, was the death of Jesus a separation from his humanity.

Maybe it's time to define Jesus' humanity...
