Whether a temporal nativity should be attributed to Christ?

Objections

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.
Objection 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.
Objection 3 : Further, properly speaking, nativity regards the person. But in Christ there is only one person. Therefore in Christ there is but one nativity.
Objection 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.
