SECOND ARTICLE [III, Q. 35, Art. 2]

Whether a Temporal Nativity Should Be Attributed to Christ?

Objection 1: It would seem that temporal nativity is not to be

attributed to Christ. For "to be born is a certain movement of a

thing that did not exist before it was born, which movement procures

for it the benefit of existence" [*Cf. Augustine, De Unit. Trin.

xii]. But Christ was from all eternity. Therefore He could not be

born in time.

Obj. 2: Further, what is perfect in itself needs not to be born. But

the Person of the Son of God was perfect from eternity. Therefore He

needs not to be born in time. Therefore it seems that He had no

temporal birth.

Obj. 3: Further, properly speaking, nativity regards the person. But

in Christ there is only one person. Therefore in Christ there is but

one nativity.

Obj. 4: Further, what is born by two nativities is born twice. But

this proposition is false; "Christ was born twice": because the

nativity whereby He was born of the Father suffers no interruption;

since it is eternal. Whereas interruption is required to warrant the

use of the adverb "twice": for a man is said to run twice whose

running is interrupted. Therefore it seems that we should not admit a

double nativity in Christ.

_On the contrary,_ Damascene says (De Fide Orth. iii): "We confess

two nativities in Christ: one of the Father--eternal; and one which

occurred in these latter times for our sake."

_I answer that,_ As stated above (A. 1), nature is compared to

nativity, as the terminus to movement or change. Now, movement is

diversified according to the diversity of its termini, as the

Philosopher shows (Phys. v). But, in Christ there is a twofold

nature: one which He received of the Father from eternity, the other

which He received from His Mother in time. Therefore we must needs

attribute to Christ a twofold nativity: one by which He was born of

the Father from all eternity; one by which He was born of His Mother

in time.

Reply Obj. 1: This was the argument of a certain heretic, Felician,

and is solved thus by Augustine (Contra Felic. xii). "Let us

suppose," says he, "as many maintain, that in the world there is a

universal soul, which, by its ineffable movement, so gives life to

all seed, that it is not compounded with things begotten, but bestows

life that they may be begotten. Without doubt, when this soul reaches

the womb, being intent on fashioning the passible matter to its own

purpose, it unites itself to the personality thereof, though

manifestly it is not of the same substance; and thus of the active

soul and passive matter, one man is made out of two substances. And

so we confess that the soul is born from out the womb; but not as

though, before birth, it was nothing at all in itself. Thus, then,

but in a way much more sublime, the Son of God was born as man, just

as the soul is held to be born together with the body: not as though

they both made one substance, but that from both, one person results.

Yet we do not say that the Son of God began thus to exist: lest it be

thought that His Divinity is temporal. Nor do we acknowledge the

flesh of the Son of God to have been from eternity: lest it be

thought that He took, not a true human body, but some resemblance

thereof."

Reply Obj. 2: This was an argument of Nestorius, and it is thus

solved by Cyril in an epistle [*Cf. Acta Concil. Ephes., p. 1, cap.

viii]: "We do not say that the Son of God had need, for His own sake,

of a second nativity, after that which is from the Father: for it is

foolish and a mark of ignorance to say that He who is from all

eternity, and co-eternal with the Father, needs to begin again to

exist. But because for us and for our salvation, uniting the human

nature to His Person, He became the child of a woman, for this reason

do we say that He was born in the flesh."

Reply Obj. 3: Nativity regards the person as its subject, the nature

as its terminus. Now, it is possible for several transformations to

be in the same subject: yet must they be diversified in respect of

their termini. But we do not say this as though the eternal nativity

were a transformation or a movement, but because it is designated by

way of a transformation or movement.

Reply Obj. 4: Christ can be said to have been born twice in respect

of His two nativities. For just as he is said to run twice who runs

at two different times, so can He be said to be born twice who is

born once from eternity and once in time: because eternity and time

differ much more than two different times, although each signifies a

measure of duration.
