I think the above could be considered, like I said above, "fighting words". It does seem to imply at least that this is not possible without the TLM.
Seems to me like they should be advocating to celebrate the Mass according to the Liturgy of St John Chrysostom, since that is far more the timeless, sacred tradition (being about 1,000 years older than the Liturgy of St Pius V).
Note: I say that as somebody who loves both the TLM and the Eastern Rite and think that both are far superior to the N.O. But to say that the E.F. Mass is truly ancient (in terms of the timeline of the Church) is laughable.
Wouldn't that make them guilty of disputing the primacy of a canonized pope?
