Q: Whether His Name Was Suitably Given to Christ?

A: On the contrary is the authority of Scripture, in which it is written (Luke 2:21): "After eight days were accomplished, that the child should be circumcised, His name was called Jesus."

I answer that,
A name should answer to the nature of a thing. This is clear in the names of genera and species, as stated Metaph. iv: "Since a name is but an expression of the definition" which designates a thing's proper nature.

Now, the names of individual men are always taken from some property of the men to whom they are given. Either in regard to time; thus men are named after the Saints on whose feasts they are born: or in respect of some blood relation; thus a son is named after his father or some other relation; and thus the kinsfolk of John the Baptist wished to call him "by his father's name Zachary," not by the name John, because "there" was "none of" his "kindred that" was "called by this name," as related Luke 1:59-61. Or, again, from some occurrence; thus Joseph "called the name of" the "first-born Manasses, saying: God hath made me to forget all my labors" (Gen. 41:51). Or, again, from some quality of the person who receives the name; thus it is written (Gen. 25:25) that "he that came forth first was red and hairy like a skin; and his name was called Esau," which is interpreted "red."

But names given to men by God always signify some gratuitous gift bestowed on them by Him; thus it was said to Abraham (Gen. 17:5): "Thou shalt be called Abraham; because I have made thee a father of many nations": and it was said to Peter (Matt. 16:18): "Thou art Peter, and upon this rock I will build My Church." Since, therefore, this prerogative of grace was bestowed on the Man Christ that through Him all men might be saved, therefore He was becomingly named Jesus, i.e. Saviour: the angel having foretold this name not only to His Mother, but also to Joseph, who was to be his foster-father.

Reply Obj. 1: All these names in some way mean the same as Jesus, which means "salvation." For the name "Emmanuel, which being interpreted is 'God with us,'" designates the cause of salvation, which is the union of the Divine and human natures in the Person of the Son of God, the result of which union was that "God is with us."

When it was said, "Call his name, Hasten to take away," etc., these words indicate from what He saved us, viz. from the devil, whose spoils He took away, according to Col. 2:15: "Despoiling the principalities and powers, He hath exposed them confidently."

When it was said, "His name shall be called Wonderful," etc., the way and term of our salvation are pointed out: inasmuch as "by the wonderful counsel and might of the Godhead we are brought to the inheritance of the life to come," in which the children of God will enjoy "perfect peace" under "God their Prince."

When it was said, "Behold a Man, the Orient is His name," reference is made to the same, as in the first, viz. to the mystery of the Incarnation, by reason of which "to the righteous a light is risen up in darkness" (Ps. 111:4).

Reply Obj. 2: The name Jesus could be suitable for some other reason to those who lived before Christ--for instance, because they were saviours in a particular and temporal sense. But in the sense of spiritual and universal salvation, this name is proper to Christ, and thus it is called a "new" name.

Reply Obj. 3: As is related Gen. 17, Abraham received from God and at the same time both his name and the commandment of circumcision. For this reason it was customary among the Jews to name children on the very day of circumcision, as though before being circumcised they had not as yet perfect existence: just as now also children receive their names in Baptism. Wherefore on Prov. 4:3, "I was my father's son, tender, and as an only son in the sight of my mother," the gloss says: "Why does Solomon call himself an only son in the sight of his mother, when Scripture testifies that he had an elder brother of the same mother, unless it be that the latter died unnamed soon after birth?" Therefore it was that Christ received His name at the time of His circumcision.
