OK then, searn77, here's more:
My five-decade experience of Orthodoxy includes both Russian and Greek versions, old-calendar and new-calendar jurisdictions, including direct family involvement (and its consequences) in Orthodox parishes of irregular canonical status. My extended family can count Roman Catholics, Lutherans and Anglicans among its ranks, as well as Orthodox.
Being exposed to all these influences has eliminated any chance of insularity. It has forced me to be dispassionate and objective. I have no personal animosity towards those not of the Orthodox faith. I have directly experienced the consequences of even innocent sacramental association with irregular Orthodox groups. I have seen for myself the ugliness and rancor that sectarianism and schism brings, be it from old-calendarist zealots, or the more recent Russian raskolniki
, who have gone their own way following the reconciliation of ROCOR and the MP in 2007.This spirit of schism can, indeed, bring with it the danger of error and, sometimes, heresy, due to the lack of proper episcopal oversight.
A single-bishop sect, or one with two or three bishops, and not in communion with anybody else is not only against the apostolic conciliar tradition (surely a cornerstone of Orthodoxy), but is downright dangerous. The image of the “ark of salvation”, which I analyzed in the "here's an icon with something for everyone" thread is a case in point. (Here's the link: http://www.orthodoxchristianity.net/forum/index.php/topic,11209.msg297730.html#msg297730
Another example of this is the promotion of the “New Testament Trinity” image as the proper and correct icon of the Holy Trinity, and the denigration of the icon originally painted by St Andrei Rublyev as uncanonical. Another is the oft-repeated claim that the adoption of the new calendar is heresy. Not so. An anomaly, and irregularity, yes. Heresy, no. If it were heresy, then, as I and others have reiterated many times before, there could be no mutual communion between the canonical Churches of Russia, of Greece, Romania, Serbia, Bulgaria, Cyprus, Antioch, Jerusalem, etc.
