I wonder what the annunciation of Jesus' conception was really like factually, what the angel's message (that is, God's own mediated message) sounded like and how it came to Mary. I imagine the months that would have passed without Mary having a period and her anguish and anxiety about what might be wrong, followed by a subtle sign here, an ambiguous symptom there, and eventually the full realization of the inexplicable fact that she was pregnant! That would have been a shock, of course, but even then, it would have taken some time for the bone deep fear to register: "I have not been intimate with a man! I can be killed or abandoned for this!" Only over more time would come first the even deeper sense that God had overshadowed her, and then, the assurance that she need not be afraid. God was doing something completely new and would stand by Mary just as he promised when he revealed himself originally to Moses as: "I will be who I will be," --- and, "I will be present to you, never leaving you bereft or barren." (Both are good translations of the name sometimes translated, "I am who am".)
In the work I do with people in spiritual direction (and in my own inner work as well), one of the tools I (ask clients to) use sometimes is dialogue. The idea is to externalize and make explicit in writing the disparate voices we carry within us: it may be a conversation between the voice of reason and the voice of fear, or the voice of stubbornness or that of impulsivity and our wiser, more flexible selves who speak to and with one another at these times so that this existence may have a future marked by wholeness, holiness, and new life. As individuals become adept at doing these dialogues, they may even discover themselves echoing or revealing at one moment the very voice of God which dwells in the deepest, most real, parts of their heart as they simultaneously bring their most profound needs and fears to the conversation. Almost invariably these kinds of dialogues bring strength and healing, integration and faith.
When I hear today's Gospel story I hear it as this kind of internal dialogue between the frightened, even bewildered Mary and the deepest, truest, part of herself which is God's own Word and Spirit (breath) calling her to a selfhood of wholeness and fruitfulness beyond all she has known before but also that stands in harmony with her people's covenant traditions and promise.

Annunciations happen to us every day: small moments that signal the advent of a new opportunity to hear, embody Christ, and gift him to others. Perhaps many are missed and fewer are heeded as Mary heeded her own and gave her fiat to the change which would make something entirely new of her life, her tradition, and her world. But Mary's story is very much our own story as well, and the Feast of Christ's nativity is meant to refer to his being born of us as well. The world into which he will be brought will not love him really --- not if he is the Jesus our Scriptures and our creeds proclaim. (We bear this very much in mind during Lent and especially at the approach of Holy Week.) But our own fiat ("Here I am Lord, I come to do your will!") will be accompanied by the reassuring voice of God: "I will overshadow you and accompany you. Our stories are joined now, inextricably wed as I say yes to you and you say yes to me. Together we create the future. Salvation will be born from this union. Be not afraid!"
