Christians venerated the Holy Milk of the Blessed Virgin Mary from the first century on. They held as sacred a white powder that was scraped from the walls of the shelter in Bethlehem where Jesus was born. Later that white powder from the stable of the Nativity was thought to be Mary’s dried milk. Three “drops of this milk” eventually made it into a medallion that emperor Charlemagne (†814) used to carry into battle. The Vatican claims that the breast milk of Mary was first contained in “Milk Grotto in Bethlehem”. The milk made the rock white, and the powder of the rock was collected and venerated as it was believed to have healing powers.

Saint Frances of Rome Obl. S. B. (†1440) is an Italian saint who founded a religious community of oblates, who share a common life without religious vows. She was canonized in 1608 by Pope Paul V and her feast is celebrated on March 9. In 1925, Pope Pius XI declared her the patron saint of automobile drivers because of a legend that an angel used to light the road before her with a lantern when she traveled, keeping her safe from hazards.
