Someone on Facebook reacted the way I would to this ubiquitous meme:
PLEASE stop referring to the Incarnation of Our Lord as an "unplanned pregnancy." It is simply not true. In fact, this was the most "planned" pregnancy in all of human history!
In Genesis, God prophesies that "I will establish a feud between thee and the woman, between thy offspring and hers; she is to crush thy head, while thou dost lie in ambush at her heels." By referring to "Her seed," God has already spoken of the Virgin Birth because a woman, properly speaking, does not have "seed." The plan was established in the very beginning.
In the seventh chapter of Isaiah, hundreds of years before the Incarnation, we are given this prophecy: "Therefore the Lord himself shall give you a sign: Behold, a virgin shall conceive, and bear a son, and shall call his name Immanuel." Again ... the prophecy recalls the plan established in the protoevangelium. This was not an "unplanned" pregnancy!
Even in the text of the Annunciation, we see completely that the plan was explained to the Blessed Virgin, who consented to the plan.
From Luke 1:26-38
When the sixth month came, God sent the angel Gabriel to a city of Galilee called Nazareth, 27 where a virgin dwelt, betrothed to a man of David’s lineage; his name was Joseph, and the virgin’s name was Mary. 28 Into her presence the angel came, and said, Hail, thou who art full of grace; the Lord is with thee; blessed art thou among women.[4] 29 She was much perplexed at hearing him speak so, and cast about in her mind, what she was to make of such a greeting. 30 Then the angel said to her, Mary, do not be afraid; thou hast found favour in the sight of God. 31 And behold, thou shalt conceive in thy womb, and shalt bear a son, and shalt call him Jesus. 32 He shall be great, and men will know him for the Son of the most High; the Lord God will give him the throne of his father David, and he shall reign over the house of Jacob eternally; 33 his kingdom shall never have an end. 34 But Mary said to the angel, How can that be, since I have no knowledge of man? 35 And the angel answered her, The Holy Spirit will come upon thee, and the power of the most High will overshadow thee. Thus this holy offspring of thine shall be known for the Son of God. 36 See, moreover, how it fares with thy cousin Elizabeth; she is old, yet she too has conceived a son; she who was reproached with barrenness is now in her sixth month, 37 to prove that nothing can be impossible with God. 38 And Mary said, Behold the handmaid of the Lord; let it be unto me according to thy word. And with that the angel left her.
It is completely wrong to refer to the Incarnation as an "unplanned pregnancy". It is untrue, it is bad theology, and it reduces the pinnacle of all salvation history to a suggested "mistake." Please, stop referring to the Virgin Birth in this manner.
May you have a blessed and grace-filled Advent!
