Those who die wearing the brown scapular as a faithful child of Mary shall not suffer eternal fire.
Taken from “The Litugical Year”:
“In the night between the 15th and 16th of July of the year 1251, the gracious Queen of Carmel confirmed to her sons by a mysterious sign the right of citizenship she had obtained for them in their newly adopted countries; as mistress and mother of the entire religious state she conferred upon them with her queenly hands the scapular hitherto the distinctive garb of the greatest and most ancient religious family of the West. On giving St. Simon Stock this badge, ennobled by contact with her sacred fingers, the Mother of God said to him: ‘Whosoever shall die in this habit shall not suffer eternal flames.’ But not against hell fire alone was the all-powerful intercession of the Blessed Mother to be felt by those who should wear her scapular. In 1316, when every holy soul was imploring heaven to put a period to that long and disastrous widowhood of the Church which followed on the death of Clement V, the Queen of Saints appeared to James d’Euse, whom the world was soon to hail as John XXII; she foretold to him his approaching elevation to the Sovereign Pontificate, and at the same time recommended him to publish the privilege she had obtained from her Divine Son for her children of Carmel – viz., a speedy deliverance from purgatory. ‘I, their Mother will graciously go down to them on the Saturday after their death, and all whom I find in purgatory I will deliver and will bring to the fountain of life eternal.’ These are the words of our Lady herself, quoted by John XXII in the Bull which he published for the purpose of making known the privilege, and which was called the Sabbatine Bull on account of the day chosen by the glorious benefactress for the exercise of her mercy. We are aware of the attempts made to nullify the authenticity of these heavenly concessions; but our extremely limited time will not allow us to follow up these worthless struggles in all their endless details. The attack of the chief assailant, the too famous Launoy, was condemned by the Apostolic See; and after, as well as before, these contradictions, the Roman Pontiffs confirmed, as much as need be, by their supreme authority, the substance and even the letter of the precious promises. The reader may find in special works the enumeration of the many indulgences with which the Popes have, time after time, enriched the Carmelite family, as if earth would vie with heaven in favoring it. The munificence of Mary, the pious gratitude of her sons for the hospitality given them by the West, and lastly, the authority of St. Peter’s successors, soon made these supernatural riches accessible to all Christians, by the institution of the Confraternity of the holy Scapular, the members whereof participate in the merits and privileges of the whole Carmelite Order. Who shall tell the graces, often miraculous, obtained through this humble garb? Who could count the faithful now enrolled in the holy militia?”
