Mark 16:19

So then after the Lord had spoken unto them, he was received up into heaven, and sat on the right hand of God.

(Con. Evang. iii. 25) By which words He seems to show clearly enough that the foregoing discourse was the last that He spake to them upon earth, though it does not appear to bind us down altogether to this opinion. For He does not say, After He had thus spoken unto them, wherefore it admits of being understood not as if that was the last discourse, but that the words which are here used, After the Lord had spoken unto them, he was received into heaven, might belong to all His other discourses. But since the arguments which we have used above make us rather suppose that this was the last time, therefore we ought to believe that after these words, together with those which are recorded in the Acts of the Apostles, our Lord ascended into heaven. (de Symbolo, 4) Let us not therefore understand this sitting as though He were placed there in human limbs, as if the Father sat on the left, the Son on the right, but by the right hand itself we understand the power which He as man received from God, that He should come to judge, who first had come to be judged. For by sitting we express habit…

For by sitting we express habitation, as we say of a person, he sat himself down in that country for many years; in this way then believe that Christ dwells at the right hand of God the Father. For He is blessed and dwells in blessedness, which is called the right hand of the Father; for all is right hand there, since there is no misery.
Mark 16:20

And they went forth, and preached every where, the Lord working with them, and confirming the word with signs following. Amen.

It goes on: And they went forth and preached every where, the Lord working with than, and confirming the word with signs and wonders.

(Epist. cxcix. 12.) (Acts 1:8) But how was this preaching fulfilled by the Apostles, since there are many nations in which it has just begun, and others in which it has not yet begun to be fulfilled? Truly then this precept was not so laid upon the Apostles by our Lord, as though they alone to whom He then spoke were to fulfil so great a charge; in the same way as He says, Behold, I am with you always, even unto the end of the world, apparently to them alone; but who does not understand that the promise is made to the Catholic Church, which though some are dying, others are born, shall be here unto the end of the world?
Matthew 1:1 · 2 passages

The book of the generation of Jesus Christ, the son of David, the son of Abraham.

Some might be perplexed by the fact that Matthew enumerates one series of ancestors, descending through David to Joseph, while Luke specifies a different succession, tracing the ancestry from Joseph backwards through David. It was easy for them to perceive that Joseph was able to have two fathers, one blood father by whom he was born and another adoptive father by whom he was adopted. Indeed, this was the custom of adoption even among that people of God. In this way they could endow sonship upon those whom they had not given birth. Recall how Pharaoh’s daughter adopted Moses (and she was a foreigner). And Jacob himself adopted his own grandsons, the sons of Joseph: “And now your two sons, who were born to you in the land of Egypt, before I came to you in Egypt, are mine; Ephraim and Manasseh shall be mine, as Reuben and Simeon are. And the offspring born to you after them shall be yours.” In this way, too, it came about that there were twelve tribes of Israel, with the tribe of Levi being given the special task of tending the temple.

Along with this one there were thirteen tribes, although there had been twelve sons of Jacob. In this way it is understood that Luke included Joseph’s father in his Gospel, not by whom he was begotten but by whom he was adopted. He recounted his ancestors upwards until he came to David.

HARMONY OF THE GOSPELS 2.3.5

(de Hær. 8, et 10.) Cerinthus then and Ebion made Jesus Christ only man; Paul of Samosata, following them, asserted Christ not to have had an existence from eternity, but to have begun to be from His birth of the Virgin Mary; he also thought Him nothing more than man. This heresy was afterwards confirmed by Photinus. (de Hæres. 19.) The error of Nestorius was, that he taught that a man only was born of the Blessed Virgin Mary, whom the Word of God received not into Unity of person and inseparable fellowship; a doctrine which Catholic ears could not endure. (de Hæres. 41.) Sabellius they say was a disciple of Noetus, who taught that the same Christ was one and the same Father and Holy Spirit. (cont. Faust. ii. 1.) Faustus affirms, that "the Gospel both begins, and begins to be so called, from the preaching of Christc, in which He no where affirms Himself to have been born of men. Nay, so far is this genealogy from being part of the Gospel, that the writer does not venture so to entitle it; beginning, 'The book of the generation,' not 'The book of the Gospel.'

(de Hæres. 41.) Sabellius they say was a disciple of Noetus, who taught that the same Christ was one and the same Father and Holy Spirit.

(cont. Faust. ii. 1.) Faustus affirms, that "the Gospel both begins, and begins to be so called, from the preaching of Christc, in which He no where affirms Himself to have been born of men. Nay, so far is this genealogy from being part of the Gospel, that the writer does not venture so to entitle it; beginning, 'The book of the generation,' not 'The book of the Gospel.' Mark again, who cared not to write of the generation, but only of the preaching of the Son of God, which is properly The Gospel, begins thus accordingly, The Gospel of Jesus Christ the Son of God. Thus then, all that we read in Matthew before the words, Jesus began to preach the Gospel of the kingdom, (Matt. 4:17.) is a part of the genealogy, not of the Gospel. I therefore betook myself to Mark and John, with whose prefaces I had good reason to be satisfied, as they introduce neither David, nor Mary, nor Joseph." To which Augustine replies, What will he say then to the Apostle's words, Remember the resurrection of Jesus Christ of the seed of David according to my Gospel. (2 Tim. 2:8.) But the Gospel of the Apostle Paul was likewise that of the other Apostles, and of all the faithful, as he says, Whether I, or they, thus have we preached the Gospel.

(de Hær. 49.) The Arians will not have the Father, Son, and Holy Spirit, to be of one and the same substance, nature, and existence; but that the Son is a creature of the Father, and the Holy Spirit a creature of a creature, i. e. created by the Son; further, they think that Christ took the flesh without a soul.

(de Trin. i. 6.) But John declares the Son to be not only God, but even of the same substance as the Father; for when he had said, The Word was God, he added, all things were made by Him; whence it is clear that He was not made by Whom all things were made; and if not made, then not created; and therefore of one substance with the Father, for all that is not of one substance with the Father is creature.

(cont. Fel. 13.) I know not what benefit the person of the Mediator has conferred upon us, if He redeemed not our better part, but took upon Him our flesh only, which without the soul cannot have consciousness of the benefit. But if Christ came to save that which had perished, the whole man had perished, and therefore needs a Saviour; Christ then in coming saves the whole man, taking on Him both soul and body.

(Lib. 83. Quæst. q. 80.) How too do they answer innumerable objections from the Gospel Scriptures, in which the Lord speaks so many things manifestly contrary to them? as is that, My soul is sorrowful even unto death, (Matt. 26:38.) and, I have power to lay down My life; (John 10:18.) and many more things of the like kind. Should they say that He spoke thus in parables, we have at hand proofs from the Evangelists themselves, who in relating His actions, bear witness as to the reality of His body, so of His soul, by mention of passions which cannot be without a soul; as when they say, Jesus wondered, was angry, and others of like kind.

(de Hæres. 55.) The Apollinarians also as the Arians affirmed that Christ had taken the human flesh without the soul. But overthrown on this point by the weight of Scripture proof, they then said that that part which is the rational soul of man was wanting to the soul of Christ, and that its place was filled by the Word itself. But if it be so, then we must believe that the Word of God took on Him the nature of some brute with a human shape and appearance. But even concerning the nature of Christ's body, there are some who have so far swerved from the right faith, as to say, that the flesh and the Word were of one and the same substance, most perversely insisting on that expression, The Word was made flesh; which they interpret that some portion of the Word was changed into flesh, not that He took to Him flesh of the flesh of the Virgind.
Matthew 1:2

Abraham begat Isaac; and Isaac begat Jacob; and Jacob begat Judas and his brethren;

(De Cons. Evan. ii. 1.) Matthew, by beginning with Christ's genealogy, shows that he has undertaken to relate Christ's birth according to the flesh. But Luke, as rather describing Him as a Priest for the atonement of sin, gives Christ's genealogy not in the beginning of his Gospel, but at His baptism, when John bare that testimony, Lo, He that taketh away the sins of the world. (John 1:29.) In the genealogy of Matthew is figured to us the taking on Him of our sins by the Lord Christ; in the genealogy of Luke, the taking away of our sins by the same; hence Matthew gives them in a descending, Luke in an ascending, series. But Matthew, describing Christ's human generation in descending order, begins his enumeration with Abraham.
Matthew 1:3

And Judas begat Phares and Zara of Thamar; and Phares begat Esrom; and Esrom begat Aram;

(de Civ. Dei, xv. 15.) Neither was Judah himself a first-born, nor of these two sons was either his first-born; he had already had three before them. So that he keeps in that line of descent, by which he shall arrive at David, and from him whither he purposed.
Matthew 1:6

And Jesse begat David the king; and David the king begat Solomon of her that had been the wife of Urias;

(De Cons. Ev. ii. 4.) Since in Matthew's genealogy is showed forth the taking on Him by Christ of our sins, therefore he descends from David to Solomon, in whose mother David had sinned. Luke ascends to David through Nathan, for through Nathan the prophet God punished David's sin; because Luke's genealogy is to show the putting away of our sins.

(Lib. Retract. ii. 16.) That is it, must be said, through a prophet of the same name, for it was not Nathan the son of David who reproved him, but a prophet of the same name.
Matthew 1:8

And Asa begat Josaphat; and Josaphat begat Joram; and Joram begat Ozias;

(Hilar. Amast. V. et N. Test. q. 85.) Or, Ochozias, Joash, and Amasias, were excluded from the number, because their wickedness was continuous and without interval. For Solomon was suffered to hold the kingdom for his father's deserts, Roboam for his son's. But these three doing evil successively were excluded. This then is an example how a race is cut off when wickedness is shown therein in perpetual succession. And Ozias begat Joatham; and Joatham begat Achaz; and Achaz begat Ezekias.
Matthew 1:16 · 3 passages

And Jacob begat Joseph the husband of Mary, of whom was born Jesus, who is called Christ.

(De Cons. Evang. ii. 2.) He is more properly called his son, by whom he was adopted, than had he been said to have been begotten of him of whose flesh he was not born. Wherefore Matthew, in saying Abraham begot Isaac, and continuing the same phrase throughout down to Jacob begot Joseph, sufficiently declares that he gives the father according to the order of nature, so as that we must hold Joseph to have been begotten, not adopted, by Jacob. Though even if Luke had used the word begotten, we need not have thought it any serious objection; for it is not absurd to say of an adopted son that he is begotten, not after the flesh, but by affection. (De Cons. Evang. ii. 4.) And suitably does Luke, who relates Christ's ancestry not in the opening of his Gospel, but at his baptism, follow the line of adoption, as thus more clearly pointing Him out as the Priest that should make atonement for sin. For by adoption we are made the sons of God, by believing in the Son of God. But by the descent according to the flesh which Matthew follows, we rather see that the Son of God was for us made man. L…

For by adoption we are made the sons of God, by believing in the Son of God. But by the descent according to the flesh which Matthew follows, we rather see that the Son of God was for us made man. Luke sufficiently shows that he called Joseph the son of Heli, because he was adopted by Heli, by his calling Adam the son of God, which he was by grace, as he was set in Paradise, though he lost it afterwards by sinning.

(De Hæres. ii.) This is said against Valentinus, who taught that Christ took nothing of the Virgin Mary, but passed through her as through a channel or pipe.

Wherefore it pleased Him to take flesh of the womb of a woman, is known in His own secret counsels; whether that He might confer honour on both sexes alike, by taking the form of a man, and being born of a woman, or from some other reason which I would not hastily pronounce on.

(De Cons. Evang. ii. 1.) It was not lawful that he should think to separate himself from Mary for this, that she brought forth Christ as yet a Virgin. And herein may the faithful gather, that if they be married, and preserve strict continence on both sides, yet may their wedlock hold with union of love only, without carnal; for here they see that it is possible that a son be born without carnal embrace.

(De Nupt. et Concup. i. 11.) In Christ's parents was accomplished every good benefit of marriage, fidelity, progeny, and a sacrament. The progeny we see in the Lord Himself; fidelity, for there was no adultery; sacrament, for there was no divorce.

(ubi sup.) Also, the line of descent ought to be brought down to Joseph, that in wedlock no wrong might be done to the male sex, as the more worthy, provided only nothing was taken away from the truth; because Mary was of the seed of David.

(Id. non occ.) Hence then we believe that Mary was in the line of David; namely, because we believe the Scripture which affirms two things, both that Christ was of the seed of David according to the flesh, and that He should be conceived of Mary not by knowledge of man, but as yet a virgin.
Since he thus related that Christ was born from Mary as a virgin and not as a result of intercourse with Joseph, for what reason does Matthew call him his father, if not because we understand Joseph to be truly the husband of Mary, not through intercourse of the flesh but in virtue of the genuine spiritual union of marriage?… All this suggests that Luke’s phrase, “as was supposed,” was inserted with a view of correcting those of the opinion that he was born from Joseph in the same way that others are born.

HARMONY OF THE GOSPELS 2.1.3

Matthew relates the human lineage of Christ in this way: After recounting the fathers from Abraham, he continues to Joseph, the husband of Mary, from whom Jesus was born. It is not fitting to think of Joseph apart from his marriage to Mary, who bore Christ as a virgin and not from intercourse with him. For by his example an incomparable commendation is made to faithful married persons of the principle that even when by common consent they maintain their continence, the marital relation can still remain steadfast and still be rightly called one of wedlock, not by virtue of physical intercourse but by the heart’s affection. This is especially so because it was possible for a son to be born to them without bodily embrace, which is intended within the purpose of procreation. Furthermore, Joseph should not have been denied being called Christ’s father on the basis that he did not beget him through intercourse. For if he had adopted a child from another, he would have rightly been the father of one who was not even born from his own wife.Indeed, Christ was even considered by some to be the…

But this was believed by those who did not know of Mary’s virginity. Luke says, “Jesus, when he began his ministry, was about thirty years of age, being the son (as was supposed) of Joseph.” Instead of naming Mary his only parent, he had not the slightest hesitation in also speaking of both parties as his parents when he says, “And the child grew and became strong, filled with wisdom; and the favor of God was upon him. Now his parents went to Jerusalem every year at the feast of the Passover.” Lest any imagine that by the “parents” here was meant only Mary and her blood relations, we do well to recall that preceding word of Luke: “And his father and mother marveled at what was said about him.”

Matthew 1:17 · 2 passages

So all the generations from Abraham to David are fourteen generations; and from David until the carrying away into Babylon are fourteen generations; and from the carrying away into Babylon unto Christ are fourteen generations.

This particular number of generations, totaling forty, is a sign of that laborious period in which, under the discipline of Christ the King, we will continue to fight against the devil. The same number was foreshadowed in both the law and the prophets, who had already solemnized a fast of forty days for the humbling of the soul (this pattern was firmly set in the narratives of Moses and Elijah, each of whom fasted for forty days). The Gospel narrative itself then again foreshadowed this same number in the fast of the Lord himself, during his forty days of temptation by the devil. What else does this narrative show than that condition of temptation which pertains to us through all the space of this age? Christ bore this temptation in the flesh when he condescended to take upon himself our own mortality.Add to this also that after his resurrection, it was his will to remain with his disciples on the earth not longer than forty days. During this time he continued to mingle his resurrected life with theirs in the form of human intercourse. He shared with them food, which mortals need for…

During this time he continued to mingle his resurrected life with theirs in the form of human intercourse. He shared with them food, which mortals need for life, even though he himself would never die. All this was done with the view of signifying to them through these forty days that although his presence would be later hidden from their eyes, he would yet fulfill what he promised when he said, “I am with you, even to the end of the world.”67
There may be other and subtler methods of accounting for the length of this age, but the most apparent anticipations within the natural order of this number are the seasons of the years, which revolve in four successive alternations. Note also the fact that the world itself has its bounds determined by four divisions (which Scripture sometimes designates by the names of the winds, east and west, north or south). The number forty then is four times the cycle-completing number ten. The number ten, of course, is itself made up by adding one, two, three and four together.

HARMONY OF THE GOSPELS 2.4.9

(De Cons. Ev. ii. 4.) Or, one of Christ's forefathers is counted twice, because in him, Jeconiah to wit, there was made a passing off to strange nations since he was carried to Babylon. Wherever a series turns out of the right line to go in any other direction there is an angle made, and that part that is in the angle is reckoned twice. Thus here is a figure of Christ, who passes from the circumcision to the uncircumcision, and is made a cornerstone. (ubi sup.) After having divided the whole into three periods of fourteen generations, he does not sum them all up and say, The sum of the whole is forty and two; because one of those fathers, that is Jeconiah, is reckoned twice; so that they do not amount to forty-two, as three times fourteen does, but because one is reckoned twice over, there are only forty-one generations. Matthew therefore, whose purpose was to draw out Christ's kingly character, counts forty successions in the genealogy exclusive of Christ.

This number denotes the time for which we must be governed by Christ in this world, according to that painful discipline which is signified by the iron rod of which it is written in the Psalms, Thou shall rule them with a rod of iron. That this number should denote this our temporal life, a reason offers at hand, in this, that the seasons of the year are four, and that the world itself is bounded by four sides, the east, and west, the north, and the south. But forty contains ten four times. Moreover, ten itself is made up by a number proceeding from one to four.
Matthew 1:18

Now the birth of Jesus Christ was on this wise: When as his mother Mary was espoused to Joseph, before they came together, she was found with child of the Holy Ghost.

(De Nupt. et Concup. i. 12.) There was no carnal knowledge in this wedlock, because in sinful flesh this could not be without carnal desire which came of sin, and which He would be without, who was to be without sin; and that hence He might teach us that all flesh which is born of sexual union is sinful flesh, seeing that Flesh alone was without sin, which was not so born. (Enchir c. 40.) Furthermore, this manner in which Christ was born of the Holy Spirit suggests to us the grace of God, by which man without any previous merits, in the very beginning of his nature, was united with the Word of God into so great unity of person, that he was also made son of God. (c. 38.). But inasmuch as the whole Trinity wrought to make this creature which was conceived of the Virgin, though pertaining only to the person of the Son, (for the works of the Trinity are indivisible,) why is the Holy Spirit only named in this work? Must we always, when one of the Three is named in any work, understand that the whole Trinity worked in that? (De Cons. Evang. ii. 5.) How this was done Matthew omits to writ…

(De Cons. Evang. ii. 5.) How this was done Matthew omits to write, but Luke relates after the conception of John, In the sixth month the Angel was sent; and again, The Holy Ghost shall come upon thee. This is what Matthew relates in these words, She was found with child of the Holy Ghost. And it is no contradiction that Luke has described what Matthew omits; or again that Matthew relates what Luke has omitted; that namely which follows, from Now Joseph her husband being a just man, to that place where it is said of the Magi, that They returned into their own country another way. If one desired to digest into one narrative the two accounts of Christ's birth, he would arrange thus; beginning with Matthew's words, Now the birth of Christ was on this wise; (Luke 1:5.) then taking up with Luke, from There was in the days of Herod, to, Mary abode with her three months, and returned to her house; then taking up again Matthew, add, She was found with child of the Holy Ghost. (Mat. 1:10.)
Matthew 1:19

Then Joseph her husband, being a just man, and not willing to make her a publick example, was minded to put her away privily.

(De Cons. Evang. ii. 5.)

(Mat. 1:10.)

Otherwise; if you alone have knowledge of a sin that any has committed against you, and desire to accuse him thereof before men, you do not herein correct, but rather betray him. But Joseph, being a just man, with great mercy spared his wife, in this great crime of which he suspected her. The seeming certainty of her unchastity tormented him, and yet because he alone knew of it, he was willing not to publish it, but to send her away privily; seeking rather the benefit than the punishment of the sinner.
Matthew 1:20

But while he thought on these things, behold, the angel of the Lord appeared unto him in a dream, saying, Joseph, thou son of David, fear not to take unto thee Mary thy wife: for that which is conceived in her is of the Holy Ghost.

(Enchir. 38.) But shall we therefore say that the Holy Spirit is the Father of the man Christ, that as God the Father begot the Word, so the Holy Spirit begot the man? This is such an absurdity, that the ears of the faithful cannot bear it. How then do we say that Christ was born by the Holy Spirit, if the Holy Spirit did not beget Him? Did He create Him? For so far as He is man He was created, as the Apostle speaks; He was made of the seed of David according to the flesh. (Rom. 1:3.) For though God made the world, yet is it not right to say that it is the Son of God, or born by Him, but that it was made, or created, or formed by Him. But seeing that we confess Christ to have been born by the Holy Spirit, and of the Virgin Mary, how is He not the Son of the Holy Spirit, and is the Son of the Virgin? It does not follow, that whatever is born by any thing, is therefore to be called the son of that thing; for, not to say that of man is born in one sense a son, in another a hair, or vermin, or a worm, none of which are his son, certainly those that are born of water and the Spirit none w…

Thus Christ was born of the Holy Spirit, and yet is the Son of God the Father, not of the Holy Spirit.
Matthew 1:21

And she shall bring forth a son, and thou shalt call his name JESUS: for he shall save his people from their sins.

Matthew 1:22-23

Now all this was done, that it might be fulfilled which was spoken of the Lord by the prophet, saying,

(Cont. Faust. 12. 45, and 13. 7.) Who so mad as to say with Manichæus, that it is a weak faith not to believe in Christ without a witness; whereas the Apostle says, How shall they believe on Him of whom they have not heard? Or how shall they hear without a preacher? (Rom. 10:14.) That those things which were preached by the Apostles might not be contemned, nor thought to be fables, they are proved to have been foretold by the Prophets. For though attested by miracles, yet there would not have been wanting men to ascribe them all to magical power, had not such suggestions been overcome by the additional testimony of prophecy. For none could suppose that long before He was born, He had raised up by magic prophets to prophesy of Him. For if we say to a Gentile, Believe on Christ that He is God, and he should answer, Whence is it that I should believe on Him? we might allege the authority of the Prophets. Should he refuse assent to this, we establish their credit from their having foretold things to come, and those things having truly come to pass. I suppose he could not but know how gre…

I suppose he could not but know how great persecutions the Christian religion has formerly suffered from the Kings of this world; let him now behold those very Kings submitting to the kingdom of Christ, and all nations serving the same; all which things the Prophets foretold. He then hearing these things out of the Scriptures of the Prophets, and beholding them accomplished throughout the whole earth, would be moved to faith.
Matthew 1:25 · 2 passages

And knew her not till she had brought forth her firstborn son: and he called his name JESUS.

It was not the visible sun, but its invisible Creator who consecrated this day for us, when the Virgin Mother, fertile of womb and integral in her virginity, brought him forth, made visible for us, by whom, when he was invisible, she too was created. A Virgin conceiving, a Virgin bearing, a Virgin pregnant, a Virgin bringing forth, a Virgin perpetual. Why do you wonder at this, O man?
Those heretics were called Antidicomarites who denied the virginity of Mary to the point that they claim that after the birth of Christ she had intercourse with her husband.
