In the past I think I’ve mentioned Scapulars, the brown one is the most common. The scapular comes from the monastic scapular which started as like an apron and is mentioned in the Rule of Benedict, as time has progressed the scapular has become a part of the habit of many monks and nuns. It is typically the outer most layer and goes from shoulder to shoulder and often covers the front and back. This is often described as the yoke of Christ and shows obedience. In the Middle Ages this was made smaller and the oblates (monks and nuns in society wore them), this lead to the development of the third orders where lay faithful would follow the Rule of the order and support them. These individuals would sometimes wear a tertiary habit like a scapular and overtime it became a high honor and great privilege to be granted a small cloth attached by bands which one wore over the torso. This is the basic devotional article which we have today.
The most common of the scapulars is the Brown one of Our Lady of Mount Carmel, it is worn by the Carmelites and by a great many of people around the world. The Vatican recognizes many different color scapulars, Brown, White, Blue, Red, Black and there are even some scapulars that combine the other scapulars together into one. As Our Lady of Fatima told the Children “The Rosary and the Scapular are inseparable.” This is why it is important, if you don’t wear a scapular it isn’t that bad it is just another devotional aid that people use. If it is at all possible make an effort to try to lead a more spirit filled life, by adding praying the Rosary or wearing a scapular.
