Let me, once again, confirm that I not passing judgment on anyone's soul, God forbid!
But there is a much deeper over-arching dynamic at work here. We are discussing the calendar issue as if this is as deep as our issue with the World Orthodox extends. The change of the calendar is merely a symptom of an underlying disease among the world religious leadership. Macrina, you are arguing that Christians need not be bound by an earthly calendar, and that such an issue is "secondary," however to tease out aspects of our faith and practice is NOT Orthodox. The Holy Fathers are clear that we take the Christian faith, the Orthodox faith, as a complete therapeutic system; we are not to alter any of it. When we begin to label and categorize things as essential and non-essential where do we draw the line? It is very seductive to begin to reconfigure "secondary" aspects of the faith and fracture the totality of Orthodoxy. What we are supposed to do is receive our faith and practice from our spiritual parents with gladness and obedience. Our teachers deliver that faith to us saying, "Here, this is the known and sure path to salvation. There is nothing you need to figure out or reform. Just do what we tell you and be faithful. That's what we did." How can a bishop say to his predecessors, "I know this has been the path that the Church has walked for nearly two millennium but I want to change it now to suit my wants." We are to take the faith and let it correct our lives from top to bottom. We are not to come to the faith to correct it. How can we assert that the Holy Spirit revealed the truth the Ecumenical Councils and the Holy Fathers who settled our calendar and now say that such a matter is secondary and open for debate?
There are some interesting questions that should be asked:
Q: Can the Church change the calendar?
A: Theoretically, yes. For instance, if something happened to the earth that slowed(or sped up) its revolution or rotation, thus changing the passage of earthly time, the Church would have the ability to address such a problem and alter the calendar as necessary.
Q: What problem does the New Calendar solve?
A: There were no issues such as my above example that we threatening the Church in 1922-23. So what was the motivation behind the parties that wanted to adopt the New Calendar? Understand, this move was coupled with much more "renovation" that was proposed to "modernize" Christ's timeless Church. In fact, as we can clearly see now, this change didn't solve problems-- it created them. It didn't heal schism it created it. It didn't combat heresy it aligned it. It didn't confirm the Orthodox Faith it betrayed it.
Even most of the clergy I come across in the New Calendar churches privately tell me that they think it was a bad idea. It's like putting highly flammable wallpaper in your home. Then you step back and say, "Wow! That was a bad idea." Then you just stand there and do nothing about it.
Q: What other changes coincided with the calendar change?
A: The calendar was changed to more closely conform to heretics! The Patriarch admitted such in his encyclical explaining to his irate faithful why he made such a move. And as thanks they ran him out of Constantinople. Furthermore, the "pan-Orthodox Congress" was not attended by representatives of the whole Church, no one from the Patriarchates of Jerusalem, Alexandria, Antioch, or Moscow was present. This was a movement by the EP to consolidate power and begin to set itself up as the equivalent of the Roman Pontiff of Orthodoxy, i.e., able to make unilateral decisions for the whole Orthodox Church. This was so successful that today there are tons of people who think that you must be in communion with the EP or you can't possibly be Orthodox.
However, in a certain way Macrina is correct: the calendar issue is secondary. The primary motivation behind it is not to change a calendar around, but to provide a template for altering the Orthodox faith. Once the precedent is set, then it becomes that much easier to slowly shift things until we have today people who have absolutely no issues with Patriarch Bartholomew standing and praying with the Pope and saying that we are "sister churches," which I have heard him say with my own ears in person. The calendar change is simply one prototype movement in a much deeper subversion of the True Faith.
