1. beards, long hair, etc., on Orthodox Bishops . . .
according to tradition, and I beleive there are also canonical rules, CLERGY are not supposed to cut thier hair or beard. This applies to ALL CLERGY, not only monks or Hierarchs. Of course, most of the anti-traditioanl anti-monastic modernist Orthodox Churches pay absolutely no attention to this whatsoever. And, of course, there are exceptions-ROCOR priests can cut their hair, shave, for secular employment if necessary. A rathr funny story-Metropolitan Philip of the Antiochian Archdiocese usually is clean shaven-but, I was told he always grows a little goatee before he goes to Synod meetings in the "Old Country," as a clean shaven face is the sign of a cuckold. Of course, since he is an unmerried clergyman, I dont know how that all fits, but, thats what I was told!
questions 2 & 3 have been answered very satisfactorily.
Since the beginning of the 20th century, the Patriarchate of Constantinople has become more and more ecumenical it seems, in each and every year. Meletios Metaxakis of Sorry Memory attempted to do away with the long hair and beards, clerical dress, and other items, and did see to the adoption of the Papal Calendar, beginning a long series of trials and sorrows for the Orthodox Church. Patriarch Athenagoras was a super ecumenicist, and his "lifting" of the anathemas do not amount to anything at all, since,not being the Eastern Pope, he had no authority to do so. This was another action that brought tribulations, and if you think the letter from Mount Athos concerning the Pope's recent visit to the Phanar was "something," you should see the letter they wrote when the anathemas were lifted!
All that these "ecumenical patriarchs" (ha-ha) have achieved is a lot of troubles, as they institute these innovations without the authority to do so, as well as ignoring the wishes of the faithful, and coming very close to heresy on many occasions. One reason for the "ecumania" of Constantinople is so they can get a lot of press in the West, and thereby soften their positon in Turkey. If the Turks think the Patriarch is as "important" as the Pope, why, they wouldn't DARE, now would they? The bottom line is that Traditional Orthodoxy is being rejected by the hierarchs of Constantinople, as well as many of their allies in the ecumenical movement. Sooner or later, this will all blow up in their faces, as a westernized, weakened, watered down Orthodoxy is wanted by no one.
