No — not where the Mass is lawfully offered, and that is most places. The faithful who attend the Traditional Latin Mass are Catholics in good standing, at Masses celebrated by validly ordained priests, in settings the Church recognizes: diocesan parishes with permission, the chapels of the priestly societies erected for this work (the FSSP, the Institute of Christ the King), and personal parishes established by Rome. Even after Traditionis Custodes (2021) the older Mass was restricted, not abrogated — and to attend it where it is permitted is to keep the Church’s law, not to break it.

The charge of “disobedience” usually confuses two different things: the canonical status of the Mass and the personal disposition of those who love it. A Catholic can prefer the older rite, find it more reverent, raise his children on it — and remain perfectly obedient. Preference is not defiance. Wanting something the Church herself called “sacred and great” is not rebellion.

Be fair to the critics, though, because there is a real case underneath the unfair version. Some who fly the banner of the old Mass do reject the Pope’s authority, or the Council, or the validity of the Novus Ordo — and the canonically irregular situation of the Society of St. Pius X (SSPX) is genuinely unsettled. Those are real problems. The mistake is to take the hard case and smear the ordinary, faithful majority with it.

So the honest line is this: attachment to the old Mass is not disobedience, and we will not pretend the disciplinary tension of 2021 does not exist either. A Catholic in communion with his bishop and the Pope, praying a Mass the Church has called venerable, is exactly where he should be — an heir, not a rebel.
