Quick reply:
3. The “ring” is the Tridentine Mass, codified by St. Pope Pius V to insure our Catholic unity for the highest form of Worship taught by the Our Lord, Jesus Christ
Even the Tridentine Mass itself is the source of some of the DEEPEST divisions among Traditional Catholics. Should the Mass be offered
una cuм the current Pontiff? Which Missale should be used? 1962, 1955, or earlier? and if we're in Holy Week, which version of Holy Week should be used? How many hours should we fast before Communion? Which version of the Good Friday prayers should be used? There are several. And heaven help us -- should the Faithful give any responses during the Mass (a la the Dialogue Mass)
These are divisions specifically among
Traditional Catholics -- 100% of whom claim allegiance and devotion to the Tridentine Mass.
So no, the Tridentine Mass is
most certainly not the Ring of my analogy. Or there would be zero division among Traditional Catholics today! Is that truly what you observe?
