Matthew 1:18

(non occ.) She was indeed espoused to Joseph, but not united in wedlock; that is to say, His mother immaculate, His mother incorrupt, His mother pure. His mother! Whose mother? The mother of God, of the Only-begotten, of the Lord, of the King, of the Maker of all things, and the Redeemer of all.

(De Spir. Sanct. ii. 5.) That which is of any thing is either of the substance or the power of that thing; of the substance, as the Son who is of the Father; of the power, as all things are of God, even as Mary was with child of the Holy Spirit.

"The birth of Jesus Christ was on this wise." "Of what kind of birth art thou telling me, I pray thee, since thou hast already mentioned His ancestors?" "I still wish to tell thee the manner also of His birth." Seest thou, how he wakens up the hearer? For as though he were about to speak of something unusual, he promises to tell also the manner thereof. And observe a most admirable order in the things he hath mentioned. For he did not proceed directly to the birth, but puts us in mind first, how many generations he was from Abraham, how many from David, and from the captivity of Babylon; and thus he sets the careful hearer upon considering the times, to show that this is the Christ who was preached by the prophets. For when thou hast numbered the generations, and hast learnt by the time that this is He, thou wilt readily receive likewise the miracle which took place in His birth. Thus, being about to tell of a certain great thing, His birth of a virgin, he first shadows over the statement, until he hath numbered the generations, by speaking of "an husband of Mary;" or rather he doth even put in short space the narration of the birth itself, and then proceeds to number also the years, reminding the hearer, that this is He, of whom the patriarch Jacob had said, He should then at length come, when the Jewish rulers had come to an end; of whom the prophet Daniel had proclaimed beforehand, that He should come after those many weeks. How then was He born, I pray thee? "When as His mother Mary was espoused:" He saith not "virgin," but merely "mother;" so that his account is easy to be received. And so having beforehand prepared the hearer to look for some ordinary piece of information, and by this laying hold of him, after all he amazes him by adding the marvellous fact, saying, "Before they came together, she was found with child of the Holy Ghost." He saith not, "before she was brought to the bridegroom's house;" for indeed she was therein. It being the way of the ancients for the most part to keep their espoused wives in their house: in those parts, at least, where one may see the same practised even now. Thus also Lot's sons-in-law were in his house with him. Mary then herself likewise was in the house with Joseph. And wherefore did she not conceive before her espousal? It was, as I said at first, that what had been done might be concealed awhile, and that the Virgin might escape every evil suspicion. For when he, who had most right of all to feel jealousy, so far from making her a show, or degrading her, is found even receiving and cherishing her after her conception; it was quite clear that, unless he had fully persuaded himself that what was done was of the operation of the Holy Spirit, he would not have kept her with him, and ministered to her in all other things. And most properly hath he said, that "she was 'found' with child," the sort of expression that is wont to be used with respect to things strange, and such as happen beyond all expectation, and are unlooked for. Proceed therefore no further, neither require anything more than what hath been said; neither say thou, "But how was it that the Spirit wrought this of a virgin?" For if, when nature is at work, it is impossible to explain the manner of the formation; how, when the Spirit is working miracles, shall we be able to express these? And lest thou shouldest weary the evangelist, or disturb him by continually asking these things, he hath said who it was that wrought the miracle, and so withdrawn himself. "For I know," saith he, "nothing more, but that what was done was the work of the Holy Ghost." Shame on them who busy themselves touching the generation on high. For if this birth, which hath witnesses without number, and had been proclaimed so long a time before, and was manifested and handled with hands, can by no man be explained; of what excess of madness do they come short who make themselves busy and curious touching that unutterable generation? For neither Gab

But why is He conceived not of a Virgin merely, but of a Virgin espoused? First, that by the descent of Joseph, Mary's family might be made known; secondly, that she might not be stoned by the Jews as an adulteress; thirdly, that in her flight into Egypt she might have the comfort of a husband. The Martyr Ignatius (vid. Ign. ad Eph. 19.) adds yet a fourth reason, namely, that his birth might be hid from the Devil, looking for Him to be born of a wife and not of a virgin. (cont. Helvid. in princ.) It is to be known, that Helvidius, a certain turbulent man, having got matter of disputation, takes in hand to blaspheme against the Mother of God. His first proposition was, Matthew begins thus, When she was espoused. Behold, he says, you have her espoused, but, as ye say, not yet committed; but surely not espoused for any other reason than as being to be married. And found by none other than by Joseph, who knew all, as being her espoused husband. (Cont. Helvid. in princip.) But says Helvidius; Neither would the Evangelist have said Before they came together, if they were not to come together afterwards; as none would say, Before dinner, where there was to be no dinner. As if one should say, Before I dined in harbour, I set sail for Africa, would this have no meaning in it, unless he were at some time or other to dine in the harbour? Surely we must either understand it thus,—that before, though it often implies something to follow, yet often is said of things that follow only in thought; and it is not necessary that the things so thought of should take place, for that something else has happened to prevent them from taking place. Therefore it by no means follows that they did come together afterwards; Scripture however shows not what did happen.

(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 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.)
