"Indeed the blessed Mary certainly did the Father's will, and so it was for her a greater thing to have been Christ's disciple than to have been his mother, and she was more blessed in her discipleship than in her motherhood. Hers was the happiness of first bearing in  her womb him whom she would obey as her master."(St. Augustine) He is reflecting on these words of Jesus: "Here are my mother and my brothers; anyone who does the will of my Father who sent me, is my brother and sister and my mother." The great grace of being the Mother of the Savior is enhanced by Mary's obedience to the Father's will in all things. Her first "fiat" at the Annunciation culminated with her silent "fiat" under the cross. In a similar way, the grace that enabled us to become sons and daughters of God is enhanced by the grace that transforms us into disciples of the Lord. Our daily "fiat", our daily "yes", to the will of God is the way we embrace this grace of discipleship. We are sons and daughters by grace and we are disciples by grace and response.
