1) If it’s not obvious, I want to clarify that most of my blogging is all part of that fides quaerens intellectum thing.
2) My problem is that the oneness of the Church seems eviscerated by a lot of ecumenical discourse, and while “Church” is a term that admits of analogical meanings, oneness is not. The existence of multiple Catholic rites–i.e. distinct Churches within the Catholic Church–is not problematic. Separation from communion with the Roman See is the problem. The One True Church includes within itself multiple Churches, but does not admit of any substantial plurality, since all those Churches are ONE by virtue of their communion with Rome. Just as the ONE God is a communion of plural persons, so the ONE Church is a communion of plural Churches.
So, to recall a key passage from Praeclara gratulationis publicae:
“We advise the reconciliation and union with the Church of Rome [implying that there is no union as things stand]; and [by union] We mean a perfect and complete union, such as could not subsist in any way if nothing else was brought about but a certain kind of agreement in the Tenets of Belief and an intercourse of Fraternal love [i.e. union can only subsist in something more than common doctrinal pledges and signs of fraternity, the latter which do not in any way comprise true union]. The True Union between Christians is that which Jesus Christ, the Author of the Church, instituted and desired, and which consists in [!] a Unity of Faith and Unity of Government.”
The Eastern Churches are indeed Churches, albeit schismatic Churches, which is Leo’s point. They have amputated themselves, so how the Church can breathe with an amputated lung, is left unexplained. Protestants are in an even more perilous place as prodigal sons. Of course LG didn’t come from nowhere, but I’m grappling with its many strands, not dogmatizing. I’m trying to resolve important tensions without resorting to the usual memory-hole tactics that so often grease the wheels of a zombified aggiornamento.
3) I agree that JPII had the Eastern Churches in mind, but a very common acceptation of the “two lungs” metaphor is meant to include the schismatic Eastern Churches. The thing I liked about Leo XIII’s quotation in my previous post, is how it showed that the idea of drawing upon the light of the East was not a new idea with JPII. On my way into the Church, I seriously grappled with becoming Eastern Orthodox, so I really do treasure the light of the East. I think I should re-read Orientale Lumen.
