FIRST ARTICLE [III, Q. 1, Art. 1]

Whether It Was Fitting That God Should Become Incarnate?

Objection 1: It would seem that it was not fitting for God to become

incarnate. Since God from all eternity is the very essence of

goodness, it was best for Him to be as He had been from all eternity.

But from all eternity He had been without flesh. Therefore it was

most fitting for Him not to be united to flesh. Therefore it was not

fitting for God to become incarnate.

Obj. 2: Further, it is not fitting to unite things that are

infinitely apart, even as it would not be a fitting union if one were

"to paint a figure in which the neck of a horse was joined to the

head of a man" [*Horace, Ars. Poet., line 1]. But God and flesh are

infinitely apart; since God is most simple, and flesh is most

composite--especially human flesh. Therefore it was not fitting that

God should be united to human flesh.

Obj. 3: Further, a body is as distant from the highest spirit as evil

is from the highest good. But it was wholly unfitting that God, Who

is the highest good, should assume evil. Therefore it was not fitting

that the highest uncreated spirit should assume a body.

Obj. 4: Further, it is not becoming that He Who surpassed the

greatest things should be contained in the least, and He upon Whom

rests the care of great things should leave them for lesser things.

But God--Who takes care of the whole world--the whole universe of

things cannot contain. Therefore it would seem unfitting that "He

should be hid under the frail body of a babe in swathing bands, in

comparison with Whom the whole universe is accounted as little; and

that this Prince should quit His throne for so long, and transfer the

government of the whole world to so frail a body," as Volusianus

writes to Augustine (Ep. cxxxv).

_On the contrary,_ It would seem most fitting that by visible things

the invisible things of God should be made known; for to this end was

the whole world made, as is clear from the word of the Apostle (Rom.

1:20): "For the invisible things of God . . . are clearly seen, being

understood by the things that are made." But, as Damascene says (De

Fide Orth. iii, 1), by the mystery of the Incarnation are made known

at once the goodness, the wisdom, the justice, and the power or might

of God--"His goodness, for He did not despise the weakness of His own

handiwork; His justice, since, on man's defeat, He caused the tyrant

to be overcome by none other than man, and yet He did not snatch men

forcibly from death; His wisdom, for He found a suitable discharge

for a most heavy debt; His power, or infinite might, for there is

nothing greater than for God to become incarnate . . ."

_I answer that,_ To each thing, that is befitting which belongs to it

by reason of its very nature; thus, to reason befits man, since this

belongs to him because he is of a rational nature. But the very

nature of God is goodness, as is clear from Dionysius (Div. Nom. i).

Hence, what belongs to the essence of goodness befits God. But it

belongs to the essence of goodness to communicate itself to others,

as is plain from Dionysius (Div. Nom. iv). Hence it belongs to the

essence of the highest good to communicate itself in the highest

manner to the creature, and this is brought about chiefly by "His so

joining created nature to Himself that one Person is made up of these

three--the Word, a soul and flesh," as Augustine says (De Trin.

xiii). Hence it is manifest that it was fitting that God should

become incarnate.

Reply Obj. 1: The mystery of the Incarnation was not completed

through God being changed in any way from the state in which He had

been from eternity, but through His having united Himself to the

creature in a new way, or rather through having united it to Himself.

But it is fitting that a creature which by nature is mutable, should

not always be in one way. And therefore, as the creature began to be,

although it had not been before, so likewise, not having been

previously united to God in Person, it was afterwards united to Him.

Reply Obj. 2: To be united to God in unity of person was not fitting

to human flesh, according to its natural endowments, since it was

above its dignity; nevertheless, it was fitting that God, by reason

of His infinite goodness, should unite it to Himself for man's

salvation.

Reply Obj. 3: Every mode of being wherein any creature whatsoever

differs from the Creator has been established by God's wisdom, and is

ordained to God's goodness. For God, Who is uncreated, immutable, and

incorporeal, produced mutable and corporeal creatures for His own

goodness. And so also the evil of punishment was established by God's

justice for God's glory. But evil of fault is committed by

withdrawing from the art of the Divine wisdom and from the order of

the Divine goodness. And therefore it could be fitting to God to

assume a nature created, mutable, corporeal, and subject to penalty,

but it did not become Him to assume the evil of fault.

Reply Obj. 4: As Augustine replies (Ep. ad Volusian. cxxxvii): "The

Christian doctrine nowhere holds that God was so joined to human

flesh as either to desert or lose, or to transfer and as it were,

contract within this frail body, the care of governing the universe.

This is the thought of men unable to see anything but corporeal

things . . . God is great not in mass, but in might. Hence the

greatness of His might feels no straits in narrow surroundings. Nor,

if the passing word of a man is heard at once by many, and wholly by

each, is it incredible that the abiding Word of God should be

everywhere at once?" Hence nothing unfitting arises from God becoming

incarnate.
