Matthew 1:18
The Annunciation to Joseph and the Birth of Jesus.
Now the birth of Jesus Christ was on this wise,
the evangelist writes. The reference is not so much to the actual process of generation, but expresses the general idea of origin. It was in this way that the Messiah assumed human nature, took upon Himself the form of our sinful flesh. As the Son of God He had no beginning, but is in the bosom of the Father from eternity, John 1:18. As a human being He had a beginning, and this origin the evangelist relates: When as His mother Mary was espoused to Joseph, before they came together, she was found with child of the Holy Ghost.
Mary had entered into a betrothal, into a contract of espousal, with Joseph. She had agreed to a marriage, she had pledged her word to Joseph, just as he was bound to her by is promise of betrothment. While Mary was in this relation to Joseph, and after she had given him her pledge as his promised bride, she still lived at her own or at her father's house. As a rule, some time elapsed before a betrothed virgin was formally given in marriage and taken to her husband's house, Deuteronomy 20:7; Judges 14:7; Judges 15:1. During this time, cohabitation did not take place, though the marriage contract was legal and binding. And it was then, before the celebration of the nuptials, that Mary was found with child. Her situation was not only delicate, but the most distressing and humiliating which could fall to the lot of a pure maiden. Knowing herself to be innocent of even the slightest transgression in deed, and fully convinced of the fact that her condition was due only to the supernatural working of the Holy Ghost, she nevertheless could expect no one to believe her defense, should she attempt one. "Nothing but the fullest consciousness of her own integrity and the strongest confidence in God could have supported her in such circumstances, where her reputation, her honor, and her life were at stake."
The Obligation of a Rightful Betrothal
In view of the fact that the modern conception of the marriage-tie is rapidly sinking to the level of the heathen idea in its most immoral manifestations, and that playing with the sanctity of the marriage-bond has become the order of the day, it is necessary to emphasize the Scriptural view of the obligation of a valid betrothal, as indicated in the text above, vv. 18-20. To maintain that passages of this kind have historical value only, that they therefore concern the Jews alone, and that their commands are not binding upon the Christians of today, is inconsistent with the demand which properly makes the Bible the rule of life as well as the norm of doctrine.
A rightful betrothal is entered upon when one man and one woman, being of marriageable age and not hindered by Scriptural or legal impediments, with the express or implied consent of their parents or guardians, and by their own free mutual consent, promise to be and remain to each other husband and wife in a lifelong union. That is the Scriptural view of a valid betrothal. And such a betrothal, without considering the Jewish police and church regulations, is, according to the Bible, tantamount to a marriage, so far as the insolubility of the marriage tie is concerned. When Lot was urged to make haste out of the doomed city of Sodom, he was sent by the angels to speak to his "sons-in-law that would marry his daughters," who were betrothed to them and intended to consummate the marriage later. Genesis 19:14. When Jacob, with the will and consent of the parents on either side, Genesis 28:2; Genesis 29:18, was betrothed to Rachel, the daughter of Laban, he spoke of her as his "wife" before the nuptials had been celebrated, Genesis 29:21. Both of these events took place before the Jewish church law was in existence. A similar case is that recorded in our passage. When Mary was "espoused to Joseph, before they came together," Joseph is called her "husband," and she is called his "wife. " And in Luke 2:5 Mary is called Joseph's "espoused wife. " See Luke 1:27; Deuteronomy 22:22; Deuteronomy 28:30; Hosea 4:13.
In addition to these clear and unmistakable passages we have another reason for considering a rightful betrothal tantamount to marriage, and that is by analogy from the parts of Holy Scriptures, both of the Old and New Testaments, in which the union of Christ and His Church is spoken of. We find throughout these passages that the terms "espoused" or "bride" (the equivalent, in the original text, of the German "Braut," a betrothed woman) and "wife" are used as synonyms and altogether indiscriminately. The great "mystery" concerning Christ and His Church, Ephesians 5:32, would lose its meaning if betrothal and marriage, as spoken of in the Word of God, were not identical. "For thy Maker is thy husband; the Lord of Hosts is His name," Isaiah 54:5. "Thou shalt no more be termed forsaken; neither shall thy land any more be termed desolate; but thou shalt be called Hephzibah and thy land Beulah; for the Lord delighteth in thee, and thy land shall be married. For as a young man marrieth a virgin, so shall thy sons marry thee; and as the bridegroom rejoiceth over the bride, so shall thy God rejoice over thee," Isaiah 62:4. "I will betroth thee unto Me forever; yea, I will betroth thee unto Me in righteousness, and in judgment, and in loving-kindness, and in mercies," Hosea 2:19. "Come with Me from Lebanon, My spouse," Song of Solomon 4:8. "He that hath the bride is the bridegroom," John 3:29. "And I, John, saw the holy city, new Jerusalem, coming down from God out of heaven, prepared as a bride adorned for her husband... Come hither, I will show thee the bride, the Lamb's wife," Revelation 21:2. Compare with these passages also the following: "The marriage of the Lamb is come, and His wife hath made herself ready," Revelation 19:7. "Husbands, love your wives, even as Christ also loved the Church," Ephesians 5:25, and the many statements in which lack of loyalty and faithfulness in the people of Israel is compared to adultery. A passage which is especially clear is 2 Corinthians 11:2.
In view of these facts there is but one conclusion: "A valid betrothal, the lawful and unconditional mutual consent of a marriageable man and a marriageable woman to be husband and wife, makes the parties to such compact essentially husband and wife before God... The rescission of lawful espousals or valid betrothal is unlawful desertion from the marriage-bond as truly as after the consummation of marriage. " "Apart from the doctrine of Scriptures regarding the obligation of the betrothal, if we only look at the engagement as we have it today and judge according to reason, that is, according to the natural moral understanding, we must consider the engagement as we have it today, with respect to its obligation, as tantamount to the consummated marriage."
