One of the signs in the tradition of the Church from many centuries ago is the Brown Scapular of Our Lady of Mount Carmel. It is a sign approved by the Church and accepted by the Carmelite Order as an external sign of love for Mary, of the trust her children have in her, and of commitment to live like her.
The word scapular indicates a form of clothing, which monks wore when they were working. With the passage of time, people began to give symbolic meaning to it: the cross to be borne every day as disciples and followers of Christ. In some religious orders, such as the Carmelites, the Scapular turned into a sign of their way of life. The Scapular came to symbolize the special dedication of Carmelites to Mary, the Mother of God, and to express trust in her motherly protection as well as the desire to be like her in her commitment to Christ and to others. Thus it became a sign of Mary.
In the Middle Ages many Christians wanted to be associated with the orders founded at that time: Franciscans, Dominicans, Augustinians, and Carmelites. Groups of lay people began to emerge in associations such as confraternities and sodalities.
All the religious orders wanted to give these lay people a sign of affiliation and of participation in their spirit and apostolate. That sign was often a part of their habit: a cloak, a cord, a scapular.
Among the Carmelites, the stage came when a smaller version of the Scapular was accepted as the sign of belonging to the Order and an expression of its spirituality.
