I'd like to hear someone explain why the Holy Fire happens on this Julian date of Pascha. I have no faith in it. Since it still relies on the Old Calendar, it doesn't line up with any astronomical or theological date of Pascha. Why would God say one thing about the stars, but then another completely opposite thing supposedly at the Holy Sepulchre? Why does it happen at this late Julian date, when even the full moon of Passover was clearly lastly week (the pink moon)? Or when the Spring equinox, ushing in the first month as described in the Bible, clearly happened with a new moon showing up last month? These are all directives on when to mark Spring and Passover in the scriptures, yet somehow the Orthodox want to insist that Julius Caesar has more authority?
This year in particular was interesting for the Gregorian Pascha as well: It lined up closer than usual, where Good Friday came after the first night of Jewish Passover (Wednesday..originally a Thursday). Sometimes there isn't as near a reflection of Holy Week as it was in the original Holy Week in the gospels.
The worst defense I've ever seen from Orthodox is that "astronomy" doesn't matter and that the Church calendar only reflects unseen, heavenly realities and doesn't necessarily have anything to do with earth or observances. We're all apparently supposedly to be living in our own world and not consider material reality. I hope someone can defend themselves better than this. It's not only asinine on it's own accord, but it goes against the scripture itself. God himself prescribed this: "Let there be lights in the vault of the sky to separate the day from the night, and let them serve as signs to mark sacred times, and days and years, and let them be lights in the vault of the sky to give light on the earth.” And it was so." - Genesis 1:15. Saying that even the sky doesn't matter reeks of Gnosticism, which stupidly spiritualizes all of life to the nth degree and negates material reality. This is the same reason why they didn't believe Christ was an actual man.
