Oh?
It SURE makes some mighty fine CLAIMS!!
"Take this Scapular.
Whosoever dies wearing it shall not suffer eternal fire.
It shall be a sign of salvation, a protection in danger and pledge of peace."
You make a common error here. A devotion is not necessary for salvation and the Church teaches that we are not to be superstitious.
If other Catholics believe that this devotion helps them, so be it. It ain’t necessary.
