Below is a link to a good article on the subject of the Apostles Fast by Elder Epiphanios Theodoropoulos. The article is written in response to criticism of those on the New Calendar by the sectarian Old Calendarists. Elder Epiphanios points out that the Apostles Fast used to be much longer than it is today even when following the Old Calendar. He points out that if the Old Calendarists condemn those on the New Calendar because this fast is sometimes reduced or eliminated altogether, they should also condemn all of the bishops and patriarchs of the previous centuries who accepted the shortening of this fast long ago.
That being said, I agree that the results of the calendar change on this and other aspects of Church life have been regrettable.
I'm very, very surprised by this article. I've never heard that in fact the fast of the Holy Apostles and the Dormition Fast used to be one, so long fasting period! So how to explain today's practice of Oriental Orthodox, who begins the Apostles' Fast on the the next day after Pentecost? When I read your post about shorting this fast, I thought you meant this OO practice. But, actually, the history of this fast is much longer and complicated. So I wonder, why is this fast not marked in the liturgical practice at all (Copts are an exception).
I think it would be better if all Orthodox (of course including Orientals) celebrated Pascha counted by old Paschalias. The feast of Pascha is one of the greatest signs of Orthodox unity, so I would like to see Malankara (actually I think some of them celebrate by Old Style), Armenians, Finland celebrating Pascha together with us. And not by Gregorian calendar, because it's against Orthodoxy (the councils, Holy Fire etc.).
But as for the lack of Apostles' Fast this year, I don't find it something completely against to Orthodoxy, because the proper date of the greatest and most important liturgical period is maintained. However, if somebody thinks it's very negative, maybe New Calendars in the years when there is no the fast of Apostles should follow OO practice?... That's just my thinking aloud
