In the sixth month, the angel Gabriel was sent from God to a town of Galilee called Nazareth, to a virgin betrothed to a man named Joseph, of the house of David, and the virgin's name was Mary. And coming to her, he said, "Hail, favored one! The Lord is with you." But she was greatly troubled at what was said and pondered what sort of greeting this might be. Then the angel said to her, "Do not be afraid, Mary, for you have found favor with God. Behold, you will conceive in your womb and bear a son, and you shall name him Jesus. He will be great and will be called Son of the Most High, and the Lord God will give him the throne of David his father, and he will rule over the house of Jacob forever, and of his kingdom there will be no end." But Mary said to the angel, "How can this be, since I have no relations with a man?" And the angel said to her in reply, "The holy Spirit will come upon you, and the power of the Most High will overshadow you. Therefore the child to be born will be called holy, the Son of God. And behold, Elizabeth, your relative, has also conceived a son in her old age, and this is the sixth month for her who was called barren; for nothing will be impossible for God." Mary said, "Behold, I am the handmaid of the Lord. May it be done to me according to your word." (Lk 1:26-38)
Mary is presented as a historical person. Her human context is given first. She is from Nazareth in Galilee; she was a virgin but betrothed to a man named Joseph; she was from the house of David and it was the sixth month. She is presented with geographical, social, chronological and family context. It will, in way be difficult for anyone to find out her situation.
In the second place she is given the divine context. She is the favoured one and God was with her. So she had nothing to fear. The Holy Spirit also will come upon her and the power of the most high will overshadow her. So she is totally on divine context.
The result of these contexts: she becomes the mother of Jesus. He is the son of God and he will also sit on the throne of David. Again, an interplay of both divine and human contexts. Yes Jesus is both son of god and son of man. Mary’s FIAT has made this interplay possible.
