I used to see Fr. Z as a sort of balanced traditionalist, at least until this particular rant.
He plays to the conspiracy theorists:
We arrive at a major problem driving various policies right now during this coronavirus challenge, now more and more it seems a “planned-demic”.
He judges millions to be in mortal sin:
Another result of this “Communion by all at every Mass” phenomenon is that, Sunday after Sunday, the Body of Christ the Church must absorb millions of body blows:
He engages in sarcasm toward faithful:
BISHOP: I want to forbid Communion on the tongue. Figure out a way.
YOUNG, GAINFULLY EMPLOYED CANONIST: My feet are like wings, Sahib!
I accept his usual agenda that everyone should receive communion his way, as it is the right way. I do not doubt that he is a good priest, though he might have been more suited to the Catholic Church of the Middle Ages. But that is no crime. A lot of people are enamored of the past.
But as to his main point, Redeptionis Sacrametuum is discipline, from Saint John Paul II. It is absurd to think that the late pontiff foresaw this development. He was addressing priest that were, for the sake of innovation, and their own personal preference (just like Fr. Z has), not giving communion in the hand. Would he be happier if these priests, or bishops, that do not trust the transmission of the virus by communion in the hand simply did not have public Mass? It seems so, and that floors me.
Then there is the issue of whether they are being obedient to the current pontiff, which he cannot possible know. Yes, there is email. But there is also the immediacy that Pope Francis could intervene if he saw the need. I see this whole issue as above his priestly pay grade.
