In the liturgy this morning we heard the Gospel from Luke 1, "...because no word shall be impossible with God. And Mary said: Behold the handmaid of the Lord, be it done to me according to thy word." In the Lutheran tradition today is Reformation Day. Although Luke is not the Gospel reading for Reformation this Gospel is certainly appropriate with its emphasis on the word, the humility and faithfulness of Mary and the blessed Incarnation. In these few words is much ecclesiological fodder.
The blessed Incarnation is as historical as the Reformation and its effects, arguably, of greater value and impact on the Church. Being more recent in history, it is easier to wrap ourselves around the Reformation.
Mary's approach to God's word is that of the holy Church's approach before the Incarnation and the ongoing work of the Word, bringing sinners to repentance and giving them forgiveness and salvation ("no word shall be impossible with God"). In a happy circumstance on Reformation Day we hear the word that leads us back to where it all began. With Mary and the one holy Church we pray, "Be it done to me according to thy word."
