I think you don’t really understand that a scapular is simply an aid to a goal, as exercise equipment is an aid to becoming stronger. The scapular comes from the habits those dedicated to the religious life used to wear as a sign of their dedication, just as a wedding ring is a sign of dedication to one’s spouse. It is not at all magic, any more than exercise equipment is.
Evidently you've not READ what is WRITTEN on the Brown Scapula!
Say what??
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.
A little piece of man-made cloth makes a prayer perfect??
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.
That's some aid!
