Ten years after Christ's resurrection, Full of Grace sheds light on a critical moment in the history of Christianity. Fraught with heresies and conflict, the early followers of Christ seek to live in a way that respects Jewish law, but with the boldness they experienced when they met Jesus of Nazareth. Mary, the mother of Jesus, quietly awaits the return of Peter, the "rock" whom Jesus asked to lead the Christian people. Arriving at Mary's home after years of traveling, preaching and narrowly escaping death, Peter expresses the overwhelming responsibility of the task set before him and his own helplessness. As Mary recalls the incredible mystery of her life with Christ, Peter re-discovers the truth: he is not leading, he is following.
