Anyone who knew no better than that about scapulars would certainly not be considered a competent religion teacher in any Catholic parish. That is superstition, a sin.
As is 99% of what the church teaches..
If my 1st communion teacher that taught me that and the Priest that enrolled me in the scapula, a "sacramental " at my first communion I would let them know Judith says they were not competent
"The Sabbatine Privilege is a special promise extended to all who wear the scapular and are enrolled in the scapular. The privilege was approved by Pope John XXII, and was later confirmed by Pope Gregory XIII, Pope Clement VII, and Pope St. Pius V. The privilege states that those souls who keep the necessary requirements of the privilege will be released from purgatory by Our Lady the Saturday after they die. The requirements are: 1.The scapular must be worn and the wearer must be enrolled in the scapular. 2. Chastity to one's state in life must be observed. 3. One must fast from meat on Wednesdays and Saturdays. 4. You must recite the Little Office of the Blessed Virgin or the rosary everyday.
Amazing....... superstitious popes..who would have guessed ??? "
Scapulars ARE superstition.
There’s zero Scriptural support for them.
