Reply Obj. 3: According to Augustine (De Consensu Evang. ii) "Matthew purposed to delineate the royal personality of Christ; Luke the priestly personality: so that in Matthew's genealogy is signified the assumption of our sins by our Lord Jesus Christ": inasmuch as by his carnal origin "He assumed 'the likeness of sinful flesh.' But in Luke's genealogy the washing away of our sins is signified," which is effected by Christ's sacrifice. "For which reason Matthew traces the generations downwards, Luke upwards." For the same reason too "Matthew descends from David through Solomon, in whose mother David sinned; whereas Luke ascends to David through Nathan, through whose namesake, the prophet, God expiated his sin." And hence it is also that, because "Matthew wished to signify that Christ had condescended to our mortal nature, he set down the genealogy of Christ at the very outset of his Gospel, beginning with Abraham and descending to Joseph and the birth of Christ Himself. Luke, on the contrary, sets forth Christ's genealogy not at the outset, but after Christ's Baptism, and not in the descending but in the ascending order: as though giving prominence to the office of the priest in expiating our sins, to which John bore witness, saying: 'Behold Him who taketh away the sin of the world.' And in the ascending order, he passes Abraham and continues up to God, to whom we are reconciled by cleansing and expiating. With reason too he follows the origin of adoption; because by adoption we become children of God: whereas by carnal generation the Son of God became the Son of Man. Moreover he shows sufficiently that he does not say that Joseph was the son of Heli as though begotten by him, but because he was adopted by him, since he says that Adam was the son of God, inasmuch as he was created by God."
Again, the number forty pertains to the time of our present life: because of the four parts of the world in which we pass this mortal life under the rule of Christ. And forty is the product of four multiplied by ten: while ten is the sum of the numbers from one to four. The number ten may also refer to the decalogue; and the number four to the present life; or again to the four Gospels, according to which Christ reigns in us. And thus "Matthew, putting forward the royal personality of Christ, enumerates forty persons not counting Him" (cf. Augustine, De Consensu Evang. ii). But this is to be taken on the supposition that it be the same Jechonias at the end of the second, and at the commencement of the third series of fourteen, as Augustine understands it. According to him this was done in order to signify "that under Jechonias there was a certain defection to strange nations during the Babylonian captivity; which also foreshadowed the fact that Christ would pass from the Jews to the Gentiles."
On the other hand, Jerome (on Matt. 1:12-15) says that there were two Joachims—that is, Jechonias, father and son: both of whom are mentioned in Christ's genealogy, so as to make clear the distinction of the generations, which the evangelist divides into three series of fourteen; which amounts in all to forty-two persons. Which number may also be applied to the Holy Church: for it is the product of six, which signifies the labor of the present life, and seven, which signifies the rest of the life to come: for six times seven are forty-two. The number fourteen, which is the sum of ten and four, can also be given the same signification as that given to the number forty, which is the product of the same numbers by multiplication.
But the number used by Luke in Christ's genealogy signifies the generality of sins. "For the number ten is shown in the ten precepts of the Law to be the number of righteousness. Now, to sin is to go beyond the restriction of the Law. And eleven is the number beyond ten." And seven signifies universality: because "universal time is involved in seven days." Now seven times eleven are seventy-seven: so that this number signifies the generality of sins which are taken away by Christ.
Reply Obj. 4: As Jerome says on Matt. 1:8, 11: "Because Joram allied himself with the family of the most wicked Jezabel, therefore his memory is omitted down to the third generation, lest it should be inserted among the holy predecessors of the Nativity." Hence as Chrysostom [*Cf. Opus Imperf. in Matth. Hom. i, falsely ascribed to Chrysostom] says: "Just as great was the blessing conferred on Jehu, who wrought vengeance on the house of Achab and Jezabel, so also great was the curse on the house of Joram, through the wicked daughter of Achab and Jezabel, so that until the fourth generation his posterity is cut off from the number of kings, according to Ex. 20:5: I shall visit [Vulg.: 'Visiting'] the iniquity of the fathers upon the children unto the third and fourth generations."
It must also be observed that there were other kings who sinned and are mentioned in Christ's genealogy: but their impiety was not continuous. For, as it is stated in the book De Qq. Vet. et Nov. Test. qu. lxxxv: "Solomon through his father's merits is included in the series of kings; and Roboam . . . through the merits of Asa," who was son of his (Roboam's) son, Abiam. "But the impiety of those three [*i.e. Ochozias, Joas, and Amasias, of whom St. Augustine asks in this question lxxxv, why they were omitted by St. Matthew] was continuous."
Reply Obj. 5: As Jerome says on Matt. 1:3: "None of the holy women are mentioned in the Saviour's genealogy, but only those whom Scripture censures, so that He who came for the sake of sinners, by being born of sinners, might blot out all sin." Thus Thamar is mentioned, who is censured for her sin with her father-in-law; Rahab who was a whore; Ruth who was a foreigner; and Bethsabee, the wife of Urias, who was an adulteress. The last, however, is not mentioned by name, but is designated through her husband; both on account of his sin, for he was cognizant of the adultery and murder; and further in order that, by mentioning the husband by name, David's sin might be recalled. And because Luke purposes to delineate Christ as the expiator of our sins, he makes no mention of these women. But he does mention Juda's brethren, in order to show that they belong to God's people: whereas Ismael, the brother of Isaac, and Esau, Jacob's brother, were cut off from God's people, and for this reason are not mentioned in Christ's genealogy. Another motive was to show the emptiness of pride of birth: for many of Juda's brethren were born of hand-maidens, and yet all were patriarchs and heads of tribes. Phares and Zara are mentioned together, because, as Ambrose says on Luke 3:23, "they are the type of the twofold life of man: one, according to the Law," signified by Zara; "the other by Faith," of which Phares is the type. The brethren of Jechonias are included, because they all reigned at various times: which was not the case with other kings: or, again, because they were alike in wickedness and misfortune. _______________________
FOURTH ARTICLE [III, Q. 31, Art. 4]
Whether the Matter of Christ's Body Should Have Been Taken from a
Woman?
Objection 1: It would seem that the matter of Christ's body should not have been taken from a woman. For the male sex is more noble than the female. But it was most suitable that Christ should assume that which is perfect in human nature. Therefore it seems that He should not have taken flesh from a woman but rather from man: just as Eve was formed from the rib of a man.
