None of our Missals (Steadman, St. Andrew, St. Joseph) describe "1-3-1" rubrics. They all describe "3."
So where did the 5/1-3-1 come from? Is it legitimate or a novelty?
Since grammar school WE, maybe not you of the 1980's, were taught that the 3's (3 Hail Mary's, 3 bells @ consecration, sets of 3 ejaculatory prayers, 3 Agnus Dei's. 3 Domine non sum dignus's, etc.) serve as a reminder of the Holy Trinity.
No 5 anywhere… ever. Even the 5 decades of the Rosary are PART of 3 x 5 decades of the full Rosary.
Yes, the "Quinity" was a wry jab, but really… what is the 5 about? Where is there a 1-3-1 in any Missal?
If this required such a low threshhold of intelligence to grasp, why did you resort to name-calling? Can you defend the 5/1-3-1 rubric from authority (not some independent priest) or not?
Perhaps it is some sort of local aberration, however its legitimacy is certainly NOT reflected in ANY Missal I have ever seen.
Do you have an authoritative defense of the aberration or not?
