Actually, it is merely
Actually, it is merely coincidence that the Orthodox Pascha always follows Passover. The current formula for calculating Easter was imposed after the early Church debate over Quartodecimenism, which celebrated the Pascha according to the Hebrew calendar. The basic problem was that with Quartodecimenism Easter could fall on any day of the week. Outside the Middle East, (as in Rome and North Africa)people were more disposed to keep Easter on Sunday because the original event was on Sunday. So a Council decreed the current formula. However, when Pope Gregory revised the calendar, the Orthodox churches refused to change their church kalendars, hence, their continued use of the Julian calendar. It is merely coincidence that for the last few centuries Orthodx Pashca always follows Passover; it was not so when the rule was first implemented. Another complication is the use of church kalendar data instead of accurate astronomical calendar data. The rule says that Easter falls on the first Sunday following the first full moon following the vernal equinox, but when I was a young man I was surprised one year to discover that Western Easter was celebrated a week later than the full moon as noted in the OFA. This, it turns out, was because of the calculations for the date of the full moon of the church kalendar, which is not astronomically accurate. Sorry, I can't remember the year.
