I had never heard of this before today. It was revealed Marie Juli Jahenny. It is supposed to preserve you through the Chastisement according to a Revelation of Jesus. I think in the USA they call it the , 'Purple Scapular'. Though here is is called, 'Violet'. Fascinating. I believe in Marie Julie though she has no Church recognition as yet. I think I'll get one. I love finding new things like this out.
