From Blessings of the Daily: A Monastic Book of Days by Brother Victor-Antoine d'Avila-Latourrette:
"Though only a memorial on the calendar, it is Our Lady's only feast in July. In addition, it is a solemn feast for the Carmelite family, who honors Mary today as their special patroness. The origins of the order goes back to the twelfth century, to Mount Carmel in Palestine, where Our Lady and the prophet Elias inspired the lifestyle of their first hermits. These hermits, following Mary's example, applied themselves to the cultivation of inner prayer and contemplation. She was their model, their protector, and their mother. Later on, when she appeared to Saint Simon Stock, she promised her special blessing to all those who would wear the habit of the order. It is not surprising, therefore, that an order singularly blessed by Our Lady has rendered great fruits of holiness throughout the centuries. One has only to think of the great Teresa of Avila, John of the Cross, Therese of Lisieux, or Edith Stein.
