I am a Muggle.
I had a visitor the other day who was very concerned about a worrying trend amongst those who are attached to to the Traditional Latin Mass. His claim was that there is an increasing trend for certain leading traddies to make a point of never attending Masses in the Usus Antiquor of priests who celebrate the Ordinary Form of the Mass. Not only that but they even refuse to attend churches where it is celebrated. He described it terms of "Purebloods" and "Muggles", the "Purebloods" refusing to mix with a Usus Utroque "Muggle" like me.
If this is so, it seems a direct contradiction of the Holy Father's thinking that is put forward in Summorum Pontificum. The Roman Rite now has two Forms, which are supposed to be mutually enriching.
Personally, I just love The Mass, I am growing increasingly attached to the usus antiquor but it is The Mass that matters. I am quite ignorant of the politics that surround the TLM but I am interested in the opinions of those who are more familiar with the byzantine politicking that surrounds it.
To be truly Catholic, in the Roman Rite means to be at home and comfortable in both forms of the Roman Rite. We are now in the third year since the publication of Summorum Pontificum at the end of this year the bishops of the world are supposed to report on the effects of the Motu Proprio to Rome, it would be sad if the had to report that this work of the Pope for unity and continuity within the Church was divisive.
All that being, said the "Pureblood" and "Muggle" thing works both ways, how many Catholics including priests and bishops refuse to have anything to do with Extraordinary Form of the Roman Rite? Of the French bishops 25% of them have celebrated or presided at the Usus Antiquior, I suspect elsewhere in the world the figure would be considerably less. No bishop or priest should categorically refuse to celebrate, let alone attend, Mass in the Extraordinary Form.
Today in the Latin Church there is no room for "Purebloods" we are all "Muggles" now.
