25 on the Julian calendar corresponds to today on the Gregorian calendar.
(Although the Russian Orthodox Church still uses the Julian calendar, the Russian government uses the Gregorian calendar just like the rest of the world, so for secular purposes, today is Jan. 25.) Because the Julian calendar has a leap year in all years divisible by four—without excepting centurial years not divisible by 400, the way the Gregorian calendar does—the discrepancy between the Julian and Gregorian calendar changes periodically. The Russian Orthodox Church is one of 15 mostly independent national churches that comprise the Eastern Orthodox Church.
The Eastern Church sets the date of Easter according to the actual, astronomical full moon and the actual equinox as observed along the meridian of Jerusalem, site of the Crucifixion and Resurrection.
The Eastern Orthodox Church also applies the formula so that Easter always falls after Passover, since the Crucifixion and Resurrection of Christ took place after he entered Jerusalem to celebrate Passover.
Essentially the Orthodox Church shares much with the other Christian Churches in the belief that God revealed himself in Jesus Christ, and a belief in the incarnation of Christ, his crucifixion and resurrection.
The Orthodox Church differs substantially in the way of life and worship.
In the UK, it is simply a matter of demographics that there are going to be problems if Orthodox believers limit their social interactions when thinking about suitable Orthodox marriage partners.
It is estimated that there are perhaps 300,000 Orthodox believers in the UK.
The Serbian, Macedonian, Georgian, and Ukrainian Orthodox Churches, like the Russian Orthodox Church, are celebrating Christmas today.is one of the autocephalous Eastern Orthodox churches, in full communion with other Eastern Orthodox patriarchates.The Primate of the ROC is the Patriarch of Moscow and all Rus'.In order to help our readers navigate this difficult terrain, we have asked five experienced Orthodox priests to share their pastoral wisdom with regard to this issue.In the secular west coast of Canada, Christians of any description are a distinct (and to some degree an embattled) minority, which makes devout Orthodox Christians even scarcer here.I consider that my priestly and pastoral task involves not so much offering available spouses to my single parishioners as offering them sound advice.If a single person in my flock were hoping to build an Orthodox marriage, I would counsel the following."It has long been recognized that to celebrate this fundamental aspect of the Christian faith on different dates," states the World Council of Churches, "gives a divided witness and compromises the churches' credibility and effectiveness in bringing the Gospel to the world." The formula for Easter—"The first Sunday after the first full moon on or after the vernal equinox"—is identical for both Western and Orthodox Easters, but the churches base the dates on different calendars: Western churches use the Gregorian calendar, the standard calendar for much of the world, and Orthodox churches use the older, Julian calendar. But actually calculating these dates involves a bewildering array of ecclesiastical moons and paschal full moons, the astronomical equinox, and the fixed equinox— and that's in addition to the two different calendar systems.The two churches vary on the definition of the vernal equinox and the full moon.Easter is not only a movable holiday but a multiple one: in most years Western Christian churches and Eastern Orthodox churches celebrate Easter on different dates.In 2015, for example, Easter will be celebrated on April 5 by Western churches and April 12 by Orthodox churches.The ROC currently claims its exclusive jurisdiction over the Orthodox Christians, irrespective of their ethnic background, who reside in the former member republics of the USSR, excluding Georgia and Armenia, although this claim is disputed in such countries as Estonia, Moldova and Ukraine and consequently parallel canonical Orthodox jurisdictions exist in those: Estonian Apostolic Orthodox Church and Metropolis of Bessarabia, respectively.It also exercises ecclesiastical jurisdiction over the autonomous Church of Japan and the Orthodox Christians resident in the People's Republic of China.But in 2014, the two celebrations occurred on the same date, April 20.
