While it is laughable that the Sister involved is appealing to a tradition of 40 years, it is not surprising.
She and those like her have become separated (re schism or rupture) from the Liturgical Tradition that existed prior to the Council.
As such, the novelty that she is defending is all that she 'knows' per se.
Following the Be Brief, Be Blunt and Be Gone guideline applied to the Sacrament of Confession, the answer that should be given is simple:
- For the past 40 years this liturgical abuse has been tolerated.
- It will be tolerated no longer
- If you want to be a protestant, then go to the protestant 'church' down the street.
