“As for Mary, she treasured all these things and pondered them in her heart.” Luke 2:19
It was the pattern of Mary’s warm relationship with Jesus and her contemplation of his “virtues and example” that would be the model for the Missionary:

1818 Rule, Part Two, Chapter One. §5 On prayer and exercises of piety
With Mary Immaculate, the faithful handmaid of the Lord, and under the guidance of the Spirit, we enter into closer union with Jesus Christ. We will contemplate with her the mysteries of the Incarnate Word, especially in praying the rosary.
CC&RR, Constitution 36
“When we have spiritual reading at meals, when we have the rosary at night, when we have study groups, forums, when we go out to distribute literature at meetings, or sell it on the street corners, Christ is there with us.” Dorothy Day
