Of the Matter From Which the Saviour's Body Was Conceived

The second man, i.e. Christ, is said to be of heaven, not indeed as to the matter from which His body was formed, but either as to the virtue whereby it was formed; or even as to His very Godhead. But as to matter, Christ's body was earthly, as Adam's body was.

As stated above (Q. 29, A. 1, ad 2) the mystery of Christ's Incarnation is miraculous, not as ordained to strengthen faith, but as an article of faith. And therefore in the mystery of the Incarnation we do not seek that which is most miraculous, as in those miracles that are wrought for the confirmation of faith, but what is most becoming to Divine wisdom, and most expedient to the salvation of man, since this is what we seek in all matters of faith.

It may also be said that in the mystery of the Incarnation the miracle is not only in reference to the matter of the conception, but rather in respect of the manner of the conception and birth; inasmuch as a virgin conceived and gave birth to God.

As stated above (Q. 15, A. 1, ad 2), Christ's body was in Adam in respect of a bodily substance—that is to say, that the corporeal matter of Christ's body was derived from Adam: but it was not there by reason of seminal virtue, because it was not conceived from the seed of man. Thus it did not contract original sin, as others who are descended from Adam by man's seed.

Faustus the Manichean argued thus, in the desire to prove that Christ is not the Son of David, because He was not conceived of Joseph, in whom Matthew's genealogy terminates. Augustine answered this argument thus (Contra Faust. xxii): "Since the same evangelist affirms that Joseph was Mary's husband and that Christ's mother was a virgin, and that Christ was of the seed of Abraham, what must we believe, but that Mary was not a stranger to the family of David: and that it is not without reason that she was called the wife of Joseph, by reason of the close alliance of their hearts, although not mingled in the flesh; and that the genealogy is traced down to Joseph rather than to her by reason of the dignity of the husband? So therefore we believe that Mary was also of the family of David: because we believe the Scriptures, which assert both that Christ was of the seed of David according to the flesh, and that Mary was His Mother, not by sexual intercourse but retaining her virginity." For as Jerome says on Matt. 1:18: "Joseph and Mary were of the same tribe: wherefore he was bound by law to marry her as she was his kinswoman. Hence it was that they were enrolled together at Bethlehem, as being descended from the same stock."

Gregory of Nazianzum answers this objection by saying that it happened by God's will, that the royal family was united to the priestly race, so that Christ, who is both king and priest, should be born of both according to the flesh. Wherefore Aaron, who was the first priest according to the Law, married a wife of the tribe of Juda, Elizabeth, daughter of Aminadab. It is therefore possible that Elizabeth's father married a wife of the family of David, through whom the Blessed Virgin Mary, who was of the family of David, would be a cousin of Elizabeth. Or conversely, and with greater likelihood, that the Blessed Mary's father, who was of the family of David, married a wife of the family of Aaron.

Again, it may be said with Augustine (Contra Faust. xxii) that if Joachim, Mary's father, was of the family of Aaron (as the heretic Faustus pretended to prove from certain apocryphal writings), then we must believe that Joachim's mother, or else his wife, was of the family of David, so long as we say that Mary was in some way descended from David.

As Ambrose says on Luke 3:25, this prophetical passage does not deny that a posterity will be born of the seed of Jechonias. And so Christ is of his seed. Neither is the fact that Christ reigned contrary to prophecy, for He did not reign with worldly honor; since He declared: "My kingdom is not of this world."

As Jerome says on Matt. 1, Isaias speaks of the generation of Christ's Godhead. Whereas Matthew relates the generation of Christ in His humanity; not indeed by explaining the manner of the Incarnation, which is also unspeakable; but by enumerating Christ's forefathers from whom He was descended according to the flesh.

Various answers have been made by certain writers to this objection which was raised by Julian the Apostate; for some, as Gregory of Nazianzum, say that the people mentioned by the two evangelists are the same, but under different names, as though they each had two. But this will not stand: because Matthew mentions one of David's sons—namely, Solomon; whereas Luke mentions another—namely, Nathan, who according to the history of the kings (2 Kings 5:14) were clearly brothers.

Wherefore others said that Matthew gave the true genealogy of Christ: while Luke gave the supposititious genealogy; hence he began: "Being (as it was supposed) the son of Joseph." For among the Jews there were some who believed that, on account of the crimes of the kings of Juda, Christ would be born of the family of David, not through the kings, but through some other line of private individuals.

Others again have supposed that Matthew gave the forefathers according to the flesh: whereas Luke gave these according to the spirit, that is, righteous men, who are called (Christ's) forefathers by likeness of virtue.

But an answer is given in the Qq. Vet. et Nov. Test. [Part i, qu. lvi; part 2, qu. vi] to the effect that we are not to understand that Joseph is said by Luke to be the son of Heli: but that at the time of Christ, Heli and Joseph were differently descended from David. Hence Christ is said to have been supposed to be the son of Joseph, and also to have been the son of Heli as though (the Evangelist) were to say that Christ, from the fact that He was the son of Joseph, could be called the son of Heli and of all those who were descended from David; as the Apostle says (Rom. 9:5): "Of whom" (viz. the Jews) "is Christ according to the flesh."

Augustine again gives three solutions (De Qq. Evang. ii), saying: "There are three motives by one or other of which the evangelist was guided. For either one evangelist mentions Joseph's father of whom he was begotten; whilst the other gives either his maternal grandfather or some other of his later forefathers; or one was Joseph's natural father: the other is father by adoption. Or, according to the Jewish custom, one of those having died without children, a near relation of his married his wife, the son born of the latter union being reckoned as the son of the former": which is a kind of legal adoption, as Augustine himself says (De Consensu Evang. ii, Cf. Retract. ii).

This last motive is the truest: Jerome also gives it commenting on Matt. 1:16; and Eusebius of Caesarea in his Church history (I, vii), says that it is given by Africanus the historian. For these writers say that Mathan and Melchi, at different times, each begot a son of one and the same wife, named Estha. For Mathan, who traced his descent through Solomon, had married her first, and died, leaving one son, whose name was Jacob: and after his death, as the law did not forbid his widow to remarry, Melchi, who traced his descent through Mathan, being of the same tribe though not of the same family as Mathan, married his widow, who bore him a son, called Heli; so that Jacob and Heli were uterine brothers born to different fathers. Now one of these, Jacob, on his brother Heli dying without issue, married the latter's widow, according to the prescription of the law, of whom he had a son, Joseph, who by nature was his own son, but by law was accounted the son of Heli. Wherefore Matthew says "Jacob begot Joseph": whereas Luke, who was giving the legal genealogy, speaks of no one as begetting.

And although Damascene (De Fide Orth. iv) says that the Blessed Virgin Mary was connected with Joseph in as far as Heli was accounted as his father, for he says that she was descended from Melchi: yet must we also believe that she was in some way descended from Solomon through those patriarchs enumerated by Matthew, who is said to have set down Christ's genealogy according to the flesh; and all the more since Ambrose states that Christ was of the seed of Jechonias.

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.

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."

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.

The male sex is more noble than the female, and for this reason He took human nature in the male sex. But lest the female sex should be despised, it was fitting that He should take flesh of a woman. Hence Augustine says (De Agone Christ. xi): "Men, despise not yourselves: the Son of God became a man: despise not yourselves, women; the Son of God was born of a woman."

Augustine thus (Contra Faust. xxiii) replies to Faustus, who urged this objection; "By no means," says he, "does the Catholic Faith, which believes that Christ the Son of God was born of a virgin, according to the flesh, suppose that the same Son of God was so shut up in His Mother's womb, as to cease to be elsewhere, as though He no longer continued to govern heaven and earth, and as though He had withdrawn Himself from the Father. But you, Manicheans, being of a mind that admits of nought but material images, are utterly unable to grasp these things." For, as he again says (Ep. ad Volus. cxxxvii), "it belongs to the sense of man to form conceptions only through tangible bodies, none of which can be entire everywhere, because they must of necessity be diffused through their innumerable parts in various places . . . Far otherwise is the nature of the soul from that of the body: how much more the nature of God, the Creator of soul and body! . . . He is able to be entire everywhere, and to be contained in no place. He is able to come without moving from the place where He was; and to go without leaving the spot whence He came."

There is no uncleanness in the conception of man from a woman, as far as this is the work of God: wherefore it is written (Acts 10:15): "That which God hath cleansed do not thou call common," i.e. unclean. There is, however, a certain uncleanness therein, resulting from sin, as far as lustful desire accompanies conception by sexual union. But this was not the case with Christ, as shown above (Q. 28, A. 1). But if there were any uncleanness therein, the Word of God would not have been sullied thereby, for He is utterly unchangeable. Wherefore Augustine says (Contra Quinque Haereses v): "God saith, the Creator of man: What is it that troubles thee in My Birth? I was not conceived by lustful desire. I made Myself a mother of whom to be born. If the sun's rays can dry up the filth in the drain, and yet not be defiled: much more can the Splendor of eternal light cleanse whatever It shines upon, but Itself cannot be sullied."

Since the Blessed Virgin was of the same nature as other women, it follows that she had flesh and bones of the same nature as theirs. Now, flesh and bones in other women are actual parts of the body, the integrity of which results therefrom: and consequently they cannot be taken from the body without its being corrupted or diminished. But as Christ came to heal what was corrupt, it was not fitting that He should bring corruption or diminution to the integrity of His Mother. Therefore it was becoming that Christ's body should be formed not from the flesh or bones of the Virgin, but from her blood, which as yet is not actually a part, but is potentially the whole, as stated in De Gener. Animal. i. Hence He is said to have taken flesh from the Virgin, not that the matter from which His body was formed was actual flesh, but blood, which is flesh potentially.

As stated in the First Part (Q. 92, A. 3, ad 2), Adam, through being established as a kind of principle of human nature, had in his body a certain proportion of flesh and bone, which belonged to him, not as an integral part of his personality, but in regard to his state as a principle of human nature. And from this was the woman formed, without detriment to the man. But in the Virgin's body there was nothing of this sort, from which Christ's body could be formed without detriment to His Mother's body.

Woman's semen is not apt for generation, but is something imperfect in the seminal order, which, on account of the imperfection of the female power, it has not been possible to bring to complete seminal perfection. Consequently this semen is not the necessary matter of conception; as the Philosopher says (De Gener. Animal. i): wherefore there was none such in Christ's conception: all the more since, though it is imperfect in the seminal order, a certain concupiscence accompanies its emission, as also that of the male semen: whereas in that virginal conception there could be no concupiscence. Wherefore Damascene says (De Fide Orth. iii) that Christ's body was not conceived "seminally." But the menstrual blood, the flow of which is subject to monthly periods, has a certain natural impurity of corruption: like other superfluities, which nature does not heed, and therefore expels. Of such menstrual blood infected with corruption and repudiated by nature, the conception is not formed; but from a certain secretion of the pure blood which by a process of elimination is prepared for conception, being, as it were, more pure and more perfect than the rest of the blood. Nevertheless, it is tainted with the impurity of lust in the conception of other men: inasmuch as by sexual intercourse this blood is drawn to a place apt for conception. This, however, did not take place in Christ's conception: because this blood was brought together in the Virgin's womb and fashioned into a child by the operation of the Holy Ghost. Therefore is Christ's body said to be "formed of the most chaste and purest blood of the Virgin."

The expression "Christ was in Adam according to bodily substance," does not mean that Christ's body was a bodily substance in Adam: but that the bodily substance of Christ's body, i.e. the matter which He took from the Virgin, was in Adam as in its active principle, but not as in its material principle: in other words, by the generative power of Adam and his descendants down to the Blessed Virgin, this matter was prepared for Christ's conception. But this matter was not fashioned into Christ's body by the seminal power derived from Adam. Therefore Christ is said to have been in Adam by way of origin, according to bodily substance: but not according to seminal virtue.

Although Christ's body was not in Adam and the other patriarchs, according to seminal virtue, yet the Blessed Virgin's body was thus in them, through her being conceived from the seed of a man. For this reason, through the medium of the Blessed Virgin, Christ is said to be of the seed of David, according to the flesh, by way of origin.

Christ and the human race are kindred, through the likeness of species. Now, specific likeness results not from remote but from proximate matter, and from the active principle which begets its like in species. Thus, then, the kinship of Christ and the human race is sufficiently preserved by His body being formed from the Virgin's blood, derived in its origin from Adam and the other patriarchs. Nor is this kinship affected by the matter whence this blood is taken, as neither is it in the generation of other men, as stated in the First Part (Q. 119, A. 2, ad 3).

Christ did not assume the flesh of the human race subject to sin, but cleansed from all infection of sin. Thus it is that "no defiled thing cometh into the Wisdom of God."

Christ is said to have assumed the first-fruits of our nature, as to the likeness of condition; forasmuch as He assumed flesh not infected by sin, like unto the flesh of man before sin. But this is not to be understood to imply a continuation of that primitive purity, as though the flesh of innocent man was preserved in its freedom from sin until the formation of Christ's body.

Before Christ, there was actually in human nature a wound, i.e. the infection of original sin. But the balm to heal the wound was not there actually, but only by a certain virtue of origin, forasmuch as from those patriarchs the flesh of Christ was to be propagated.

—

Because the Blessed Virgin was conceived in original sin, she was in Abraham as needing to be healed. Therefore she paid tithes in him, as descending from him according to seminal virtue. But this is not true of Christ's body, as stated above.

Christ's flesh is said to have been subject to sin, according as it was in the patriarchs, by reason of the condition in which it was in His forefathers, who paid the tithes: but not by reason of its condition as actually in Christ, who did not pay the tithes.

The levitical priesthood was handed down through carnal origin: wherefore it was not less in Abraham than in Levi. Consequently, since Abraham paid tithes to Melchisedech as to one greater than he, it follows that the priesthood of Melchisedech, inasmuch as he was a figure of Christ, was greater than that of Levi. But the priesthood of Christ does not result from carnal origin, but from spiritual grace. Therefore it is possible that a father pay tithes to a priest, as the less to the greater, and yet his son, if he be a bishop, is greater than that priest, not through carnal origin, but through the spiritual grace which he has received from Christ.

Thus the answer to the first objection is made manifest.
