FIFTH ARTICLE [III, Q. 1, Art. 5]

Whether It Was Fitting That God Should Become Incarnate in the

Beginning of the Human Race?

Objection 1: It would seem that it was fitting that God should become

incarnate in the beginning of the human race. For the work of the

Incarnation sprang from the immensity of Divine charity, according to

Eph. 2:4, 5: "But God (Who is rich in mercy), for His exceeding

charity wherewith He loved us . . . even when we were dead in sins,

hath quickened us together in Christ." But charity does not tarry in

bringing assistance to a friend who is suffering need, according to

Prov. 3:28: "Say not to thy friend: Go, and come again, and tomorrow

I will give to thee, when thou canst give at present." Therefore God

ought not to have put off the work of the Incarnation, but ought

thereby to have brought relief to the human race from the beginning.

Obj. 2: Further, it is written (1 Tim. 1:15): "Christ Jesus came into

this world to save sinners." But more would have been saved had God

become incarnate at the beginning of the human race; for in the

various centuries very many, through not knowing God, perished in

their sin. Therefore it was fitting that God should become incarnate

at the beginning of the human race.

Obj. 3: Further, the work of grace is not less orderly than the work

of nature. But nature takes its rise with the more perfect, as

Boethius says (De Consol. iii). Therefore the work of Christ ought to

have been perfect from the beginning. But in the work of the

Incarnation we see the perfection of grace, according to John 1:14:

"The Word was made flesh"; and afterwards it is added: "Full of grace

and truth." Therefore Christ ought to have become incarnate at the

beginning of the human race.

_On the contrary,_ It is written (Gal. 4:4): "But when the fulness of

the time was come, God sent His Son, made of a woman, made under the

law": upon which a gloss says that "the fulness of the time is when

it was decreed by God the Father to send His Son." But God decreed

everything by His wisdom. Therefore God became incarnate at the most

fitting time; and it was not fitting that God should become incarnate

at the beginning of the human race.

_I answer that,_ Since the work of the Incarnation is principally

ordained to the restoration of the human race by blotting out sin, it

is manifest that it was not fitting for God to become incarnate at

the beginning of the human race before sin. For medicine is given

only to the sick. Hence our Lord Himself says (Matt. 9:12, 13): "They

that are in health need not a physician, but they that are ill . . .

For I am not come to call the just, but sinners."

Nor was it fitting that God should become incarnate immediately after

sin. First, on account of the manner of man's sin, which had come of

pride; hence man was to be liberated in such a manner that he might

be humbled, and see how he stood in need of a deliverer. Hence on the

words in Gal. 3:19, "Being ordained by angels in the hand of a

mediator," a gloss says: "With great wisdom was it so ordered that

the Son of Man should not be sent immediately after man's fall. For

first of all God left man under the natural law, with the freedom of

his will, in order that he might know his natural strength; and when

he failed in it, he received the law; whereupon, by the fault, not of

the law, but of his nature, the disease gained strength; so that

having recognized his infirmity he might cry out for a physician, and

beseech the aid of grace."

Secondly, on account of the order of furtherance in good, whereby we

proceed from imperfection to perfection. Hence the Apostle says (1

Cor. 15:46, 47): "Yet that was not first which is spiritual, but that

which is natural; afterwards that which is spiritual . . . The first

man was of the earth, earthy; the second man from heaven, heavenly."

Thirdly, on account of the dignity of the incarnate Word, for on the

words (Gal. 4:4), "But when the fulness of the time was come," a

gloss says: "The greater the judge who was coming, the more numerous

was the band of heralds who ought to have preceded him."

Fourthly, lest the fervor of faith should cool by the length of time,

for the charity of many will grow cold at the end of the world. Hence

(Luke 18:8) it is written: "But yet the Son of Man, when He cometh,

shall He find think you, faith on earth?"

Reply Obj. 1: Charity does not put off bringing assistance to a

friend: always bearing in mind the circumstances as well as the state

of the persons. For if the physician were to give the medicine at the

very outset of the ailment, it would do less good, and would hurt

rather than benefit. And hence the Lord did not bestow upon the human

race the remedy of the Incarnation in the beginning, lest they should

despise it through pride, if they did not already recognize their

disease.

Reply Obj. 2: Augustine replies to this (De Sex Quest. Pagan., Ep.

cii), saying (Q. 2) that "Christ wished to appear to man and to have

His doctrine preached to them when and where He knew those were who

would believe in Him. But in such times and places as His Gospel was

not preached He foresaw that not all, indeed, but many would so bear

themselves towards His preaching as not to believe in His corporeal

presence, even were He to raise the dead." But the same Augustine,

taking exception to this reply in his book (De Perseverantia ix),

says: "How can we say the inhabitants of Tyre and Sidon would not

believe when such great wonders were wrought in their midst, or would

not have believed had they been wrought, when God Himself bears

witness that they would have done penance with great humility if

these signs of Divine power had been wrought in their midst?" And he

adds in answer (De Perseverantia xi): "Hence, as the Apostle says

(Rom. 9:16), 'it is not of him that willeth nor of him that runneth,

but of God that showeth mercy'; Who (succors whom He will of) those

who, as He foresaw, would believe in His miracles if wrought amongst

them, (while others) He succors not, having judged them in His

predestination secretly yet justly. Therefore let us unshrinkingly

believe His mercy to be with those who are set free, and His truth

with those who are condemned." [*The words in brackets are not in the

text of St. Augustine].

Reply Obj. 3: Perfection is prior to imperfection, both in time and

nature, in things that are different (for what brings others to

perfection must itself be perfect); but in one and the same,

imperfection is prior in time though posterior in nature. And thus

the eternal perfection of God precedes in duration the imperfection

of human nature; but the latter's ultimate perfection in union with

God follows.
