Whether mission is eternal, or only temporal?

Objections

Objection 1 : It would seem that mission can be eternal. For Gregory says (Hom. xxvi, in Ev.), "The Son is sent as He is begotten." But the Son's generation is eternal. Therefore mission is eternal.
Objection 2 : Further, a thing is changed if it becomes something temporally. But a divine person is not changed. Therefore the mission of a divine person is not temporal, but eternal.
Objection 3 : Further, mission implies procession. But the procession of the divine persons is eternal. Therefore mission is also eternal.
