Here is the link to a lovely conversation with Dr Danielle Peters, who is a member of the Secular Institute of the Schoenstatt Sisters of Mary, and a research fellow at the Institute for Church Life at Notre Dame University, IN. She obtained her MA in theology from Sacred Heart Seminary in Wisconsin and her STL and STD from the International Marian Research Institute (IMRI) in Dayton OH. Her former assignments include professor and coordinator of academic programs at the Pontifical International Marian Research Institute (IMRI) in Dayton, OH, the Athenaeum in Cincinnati, OH, and employment at the Congregation for the Doctrine of the Faith in the Vatican.
The Schoenstatt prayer to the Blessed Mother that she recited is as follows:
Let us walk like you through life
Let us mirror you forever
Strong and noble; meek and mild
Peace and love be our endeavor
Walk in us through our world
Make it ready for the Lord
She is the author of Ecce educatrix tua: the role of the Blessed Virgin Mary for a pedagogy of holiness in the thought of John Paul II and Father Joseph Kentenich, numerous articles, and is a regular contributor to the Church Life Journal. She currently serves as the vice president of the Mariological Society of America (2014-16). Or after May 20: She serves as president of the Mariological Society of America (2016-18).
I referred to the following resources:
As for the Protoevangelium of James, she explains:
writings such as the Protoevangelium of St. James are non-canonical writings from the early church. From this piece the Catholic tradition accepts the names of Mary's parents and her Presentation in the Temple (celebrated on November 21). It also includes stories about the person of St. Joseph and of Mary's midwife, Salome, who doubted her virginity after birth (and when she wanted to have a physical examination her right hand withered .... Some of these episodes (including the two step Annunciation at the well and then in Mary's house) made it into iconography. I guess, as with everything we love, we want to know more details and this writing wanted to fill the gap.
