...Christians of my acquaintance are either not aware of, or manage to belittle or dismiss, that fact, as you are doing here.
The Christians of your acquaintance argument is covered by a number of logical fallacies – they don't determine doctrine, clearly. Nor can I answer for the opinions of people I don't know and have never met, and you might well have misconstrued, as you misconstrue me.
Not correct. The Church has taken that upon itself with no right to do so. Burn me at the stake, my answer will not change.
That's your right, and I respect it, even though you're wrong.
So it just happened to line up with a Pagan Spring Fertility Festival?
Both Hebrew and Christian calendars line up with the celebration of Spring – so is the coincidence inclusive of the Jews?
The Torah commands “Guard the month of spring, and make [then] the Passover offering.” (Deuteronomy 16:1).
This directive to the Sanhedrin required them to constantly adjust the calendar to ensure that the celebration of the Passover always fell around the Spring Full Moon.
Prior to the fall of Jerusalem, the Sanhedrin would determine whether it should be declared a leap year. The primary factor was the spring equinox. If the spring equinox would fell Nisan 16 or later, then a leap year was declared.
However, the observation of spring-like conditions needed to be evidenced. If the barley had not yet ripened, and the trees were not in blossom, then that was sufficient reason to delay Nisan by adding a leap-month (Adar II). Spring needed to be felt; it should be bright and green.
(Even factors like roads or bridges in disrepair due to the winter, impeding the ability of the pilgrims to travel to Jerusalem for Passover, was sufficient to announce a leap year.)
Thus the Jewish calendar is 'worked' to ensure Passover falls on the Full Moon in Spring.
After the fall of Jerusalem, in the 4th century, a revised calendar was introduced, with a fixed leap-month added 7 years out of a 19-year cycle.
The early Christians used the Jewish calendar, celebrating the Resurrection on the first Sunday after Nisan 15. At Nicaea, with relations between Jews and Christians being what they were (bad, a long time before Constantine), and the fact that Nisan 15 was a moveable feast, the Council decided to set the date independent of Jewish reckoning.
Bearing in mind that both Christians and Jews work the calendar to establish a date on or after the Spring Full Moon, and both have changed calendar reckoning as they see fit, I think the argument against Nicaea is a weak one.
Looking at this Jewish website, let's incorporate this:
" ... you’re correct that the Torah refers to Passover on the 14th... "
The explanation why it is celebrated on Nisan 15 is based on Tradition – with sound reasoning – not Scripture.
"... the weeklong celebration is consistently called the Festival of Matzahs in the Torah, it has come to be known as Pesach, or Passover, in common parlance and even in our liturgy."
So "Pasch" or "Passover" is Traditional, not Scriptural.
The calendars do occasionally line up. In 2018 and 2019, the first night of Passover fell on Good Friday.
The calendar is also worked that Passover can never fall on a Thursday. If Passover started on a Thursday, that would push Rosh Hashanah the following year to start on Saturday – and neither Rosh Hashanah nor Yom Kippur can fall the day after Shabbat.
... since the Catholic Church does not recognize Jesus as the *Paschal* Lamb ..."
OK, bored now. I'm gonna take a page out of Bananabrain's book here ('Hur hur hur') – That's utter nonsense (he would have said 'b*ll*cks').
If you can't dazzle 'em with brilliance, baffle 'em with b.s....
Ad hominem... speak for yourself ... yadda yadda ...
