"The Tridentine rite is used only in the liturgy celebrated according to the 1962 Roman Missal."
I mean, it's not wrong.... that ritual does indeed occur only during, well..... during ITSELF.
It's just an oddly obvious thing for a Catholic journalist to say.
Like, the Holy Father appears only at events at which the Pope is present.
Or, Sunday Mass is only held in Eucharistic Liturgies on the first day of the week.
