The perspective which the Carmelite mystic employs in this drawing accentuates the κατάβασις (katábasis), the descent of Christ in his voluntary humiliation and suffering.
"For let this mind be in you, which was also in Christ Jesus: Who being in the form of God, thought it not robbery to be equal with God: But emptied himself, taking the form of a servant, being made in the likeness of men, and in habit found as a man. He humbled himself, becoming obedient unto death, even to the death of the cross." -- Philippians 2: 5-8
