SECOND ARTICLE [I, Q. 43, Art. 2]

Whether Mission Is Eternal, or Only Temporal?

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.

Obj. 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.

Obj. 3: Further, mission implies procession. But the procession of

the divine persons is eternal. Therefore mission is also eternal.

_On the contrary,_ It is said (Gal. 4:4): "When the fullness of the

time was come, God sent His Son."

_I answer that,_ A certain difference is to be observed in all the

words that express the origin of the divine persons. For some express

only relation to the principle, as "procession" and "going forth."

Others express the term of procession together with the relation to

the principle. Of these some express the eternal term, as

"generation" and "spiration"; for generation is the procession of the

divine person into the divine nature, and passive spiration is the

procession of the subsisting love. Others express the temporal term

with the relation to the principle, as "mission" and "giving." For a

thing is sent that it may be in something else, and is given that it

may be possessed; but that a divine person be possessed by any

creature, or exist in it in a new mode, is temporal.

Hence "mission" and "giving" have only a temporal significance in

God; but "generation" and "spiration" are exclusively eternal;

whereas "procession" and "giving," in God, have both an eternal and a

temporal signification: for the Son may proceed eternally as God; but

temporally, by becoming man, according to His visible mission, or

likewise by dwelling in man according to His invisible mission.

Reply Obj. 1: Gregory speaks of the temporal generation of the Son,

not from the Father, but from His mother; or it may be taken to mean

that He could be sent because eternally begotten.

Reply Obj. 2: That a divine person may newly exist in anyone, or be

possessed by anyone in time, does not come from change of the divine

person, but from change in the creature; as God Himself is called

Lord temporally by change of the creature.

Reply Obj. 3: Mission signifies not only procession from the

principle, but also determines the temporal term of the procession.

Hence mission is only temporal. Or we may say that it includes the

eternal procession, with the addition of a temporal effect. For the

relation of a divine person to His principle must be eternal. Hence

the procession may be called a twin procession, eternal and temporal,

not that there is a double relation to the principle, but a double

term, temporal and eternal.
