There are stages on the road to becoming Orthodox, just as a couple moves through stages in their relationship before meeting at the altar to become married.
Likewise, once you are Orthodox it is a serious commitment, just as marriage is a lifelong commitment, so to is being an Orthodox Christian.
As mentioned above, there is a difference of 13 days between the Gregorian and the Julian calendars.
Eventually, all of the Western Churches adopted this “New” calendar.
The result being that today we celebrate most feast days, like Christmas, Epiphany and the rest, at the same time as Western Christians and only Pascha and the feast days that are connected with it like Pentecost and the Ascension, are dated according to the Julian calendar and celebrated on different dates.
However, becoming Orthodox can be described the same as the sacrament of marriage.
Especially those of us who have families that are not Orthodox wonder why we have to celebrate this important holiday at different times.
In order to better understand why we do, we will take a closer look at how the date of Pascha is calculated and also examine the issue of the calendar.
The Orthodox Church continues to follow this formula exactly as prescribed by the Council of Nicea.
However, in modern times, the Western Church has rejected the part of the Nicene formula that requires that Pascha “always follow the Jewish Passover.” Western theologians (and, unfortunately, a few misguided Orthodox Theologians as well) now claim that this provision was never a part of the council’s intention, saying that it is not necessary for Pascha to follow the Jewish Passover.
