What is the Carmelite Scapular?

The Scapular of Our Lady of Mount Carmel (also known as the Brown Scapular) is the habit of the Carmelite Order. According to the Vatican's Congregation for Divine Worship, the Brown Scapular is "an external sign of the filial relationship established between the Blessed Virgin Mary, Mother and Queen of Mount Carmel, and the faithful who entrust themselves totally to her protection, who have recourse to her maternal intercession, who are mindful of the primacy of the spiritual life and the need for prayer.
