The suffering on the cross completed the process of glorification (meaning the uniting of the Lord’s divine-human nature to the divine nature of the Father). The Lord himself says so in the Gospels:
“After Judas left, Jesus said, ‘Now the Son of Humankind is glorified, and God is glorified in him. If God is glorified in him, God will also glorify him in himself and glorify him immediately’” (John 13:31, 32).
Here glorification refers to both God the Father and the Son; it says
“God is glorified in him and will glorify him in himself.”
Clearly this means that they became united.
