Testimony from Angelina below...
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.
True devotion to the Blessed Virgin Mary consists in three things: VENERATION, CONFIDENCE AND LOVE. By simply wearing the Scapular, we can tell her every moment of the day that we venerate her, love her and trust in her protection.
As Our Lord taught us to say the Our Father, Our Blessed Mother taught us the value of the scapular. When we use it as a prayer, Our Lady draws us to the Sacred Heart of Her Divine Son. It is good, therefore, to hold the scapular in the hand. A prayer offered while holding the Scapular is as perfect as a prayer can be. It is especially in time of temptation that we need the powerful intercession of God’s Mother. The evil spirit is utterly powerless when the wearer of a scapular faces temptation, calling upon the Holy Virgin in this silent devotion. “If you had recommended yourself to me, you would not have run into such danger,” was Our Lady’s gentle reproach to Blessed Alan de la Roche, one of her devoted servants.
