Nah! I call faulty only that which YOU have artificially constructed and put forth to be the "unanimous witness of the pleroma of the Church".
At least you're honest. Your faulty logic does absolutely nothing to prove (to anyone but yourself) your original claim that the New Calendar is not in error, but at least you're honest.
What I'm driving at is that you ignore the witness of those who disagree with you (i.e., those who condemn the New Calendar) and cite as authoritative the unanimous witness of those who agree with you. By definition, this is the logical fallacy known as "stacking the deck".
The only witness I will admit as meaningful is that of the Orthodox Church, and I define that as the Patriarchies, the autocephalies and the autonomies which maintain communion with one another. If that is "stacking the deck" so be it. My "deck" cannot but lie with the canonical bishops of the Orthodox Church. Other witness and opinions, whether from the Celtic Orthodox Church or the Russian Zarist Church, have little relevance.
I find it hard to believe that you reject the unanimous witness of the pleroma of the Church as "faulty logic."
Don't ask me to define my meaning again, for I already have.
Well, I am not sure if I have seen your definition. But I am happy to provide my definitive list for the pleroma of the Church. Here is a list (hope it is complete.)

1. Patriarchate of Constantinople
2. Patriarchate of Alexandria
3. Patriarchate of Antioch
4. Patriarchate of Jerusalem
5. Patriarchate of Moscow
6. Patriarchate of Serbia
7. Patriarchate of Romania
8. Patriarchate of Bulgaria
9. Patriarchate of Georgia
10. Church of Cyprus
11. Church of Greece
12. Church of Poland
13. Church of Albania
14. Church of the Czech Lands and Slovakia
15. Orthodox Church in America
16. Church of Sinai
17. Church of Finland
18. Church of Estonia
19. Church of Japan
20. Church of Ukraine
