The solemnity is observed even when July 16 falls on a Sunday. The sacred scriptures speak of the beauty of Mount Carmel where the prophet Elijah defended the faith of Israel in the living God. There, at the beginning of the thirteenth century, under the title of Saint Mary of Mount Carmel, the Order of Carmelites had its formal beginning.
From the fourteenth century this title, recalling the countless blessings of its patroness, began to be celebrated solemnly, first in England and then gradually throughout the whole Order. It attained its supreme place from the beginning of the seventeenth century, when the General Chapter declared it to be the principal feast of the Order, and Paul V recognized it as the feast of the Scapular Confraternity.
