8. The restored Roman Calendar gives particular prominence to the celebrations listed above, but it also includes other kinds of commemorations connected with local devotions and which have acquired a wider popularity and interest (e.g., February 11, Our Lady of Lourdes; August 5, the Dedication of the Basilica of St. Mary Major). Then there are others, originally celebrated by particular religious families but which today, by reason of the popularity they have gained, can truly be considered ecclesial (e.g., July 16, Our Lady of Mount Carmel; October 7, Our Lady of the Rosary). There are still others which, apart from their apocryphal content, present lofty and exemplary values and carry on venerable traditions having their origin especially in the East (e.g., the Immaculate Heart of the Blessed Virgin, celebrated on the Saturday following the second Sunday after Pentecost).

“The Carmelite Scapular’s nobility of origin, its extraordinary spread among Christian peoples for many centuries, the spiritualizing effects produced by it and the outstanding miracles worked in virtue of it render the Scapular of Carmel commendable to a wondrous degree.”  --  Pope Leo XIII

In the year 1251, in the town of Aylesford in England, Our Lady appeared to St. Simon Stock, a Carmelite. She handed him a brown woolen scapular and said, “This shall be a privilege for you and all Carmelites, that anyone dying in this habit shall not suffer eternal fire.” In time, the Church extended this magnificent privilege to all the laity who are willing to be invested in the Brown Scapular of the Carmelites and who perpetually wear it.
