Why a difference in date for Orthodox and Catholic Pascha?

"Why Do the Orthodox Sometimes Celebrate Pascha (Easter) on a Different Day from Roman Catholics?" by Priest Basil Biberdorf

Sigh. It's time for that annual round of ABSOLUTELY WRONG "Why Orthodox Pascha [Easter] doesn't line up with Western Easter every year" articles.

It's very simple. The basic principle is: Pascha happens the first Sunday following the first full moon following the vernal (spring) equinox, which is assumed as the invariant date of March 21. This was established by the First Ecumenical Council, held in Nicaea in AD 325.

The differences arise because:
  1. The Orthodox use March 21 on the Julian (Old) Calendar, which differs by some 13 days from the Gregorian (New) Calendar. If a full moon occurs in this interval, the Paschal dates will be off by quite a bit.
  2. The full moon is determined not by observation but according to tables that say when it is according to the year in a cycle. The Orthodox have a different table than the Roman Catholics (and, consequently, the Western Protestants).
The differences have nothing to do with observing Pascha after Passover. The first Nicaean Council explicitly de-linked Pascha from Passover, which, due to Jewish rabbinical decisions could move from year to year. The Council wanted to free the Christian Church from this variability.

    But it’s not to avoid variability. It’s to avoid dependence upon Jewish authorities.

    The underlying calculation for Pascha is based upon the underlying calculation for Passover.

      ....if you believe the Gregorian is more accurate. Funny thing about the Julian, it's still used for astronomical measurements. The Gregorian is broken and dates that you see are translated. Then there is the 28year cycle in the Julian that is lost in the Gregorian. No, the Julian is a better calendar.

Sr. Vassa: There's no ontological impediment to priestesses

Image
Is the male-only priesthood a discipline or essential to the nature of being a priest? Sr. Vassa (again unflinchingly taking up a contentious topic by climbing up the ladder to the highest platform and then jumping into the deep end head first) dives right in and says there is no reason beyond personal preference to not have female clergy. You know, when people ask me about women in priesthood, they say, 'Sister, why can't women be priests?' And I say, 'Women CAN be priests. We don't WANT them to be priests.' Because you see, God can do anything, and the Church, by divine authority, uh, can do anything, but, the Church doesn't want to - and that's a legitimate reason. What I don't like is when we TRY to pretend that there are other reasons for this, because it's legitimate not to want something, and there are reasons not to want this - right? - but, we shouldn't pretent that there's some... reason, that, for example, the maleness...

OCA takes strong stand for canonical Orthodoxy

( Orthochristian.com ) - The primate of the Orthodox Church in America, His Beatitude Metropolitan Tikhon of Washington and All America and Canada, will concelebrate with the primate of the canonical Ukrainian Orthodox Church, His Beatitude Metropolitan Onuphry of Kiev and All Ukraine, in western Ukraine later this week. The Ukrainian Orthodox Diocese of Chernivtsi and Bukovina “awaits the visit of the primate of the Orthodox Church in America on June 1–2, 2024. Solemn services will be held in the Cathedral of the Descent of the Holy Spirit in Chernivtsi, with the participation of both primates.” The Holy Synod of the Orthodox Church in America formally rejects communion with the schismatics of the “Orthodox Church in Ukraine,” recognizing only the canonical UOC under Met. Onuphry. The Ukrainian primate was the honored guest at the OCA’s 18th All-American Council in July 2015.
