The Resurrection of Jesus was NOT on Sunday

Jesus died at 3PM, by the end of that day He has been in the grave for 3 hours, not the two hours the vid claims. That partial day was torture the whole day so it is day 1. The 1st night was Thursday night (Passover), Friday night (regular Sabbath), Sunday night regular week day.

The vid also has him reading that Mary came at dawn and then he tries to change it to evening being the dawn.

Who cares what day it happened on.

I want to know where the Grail is.

It was the Elixir of Life that caused the Resurrection.

Doesn't really matter what name we put on the day, because due to the extra leap seconds and leap years and so, sunday has been changing "days" ever since we started using this calendar.. In other words it's an arbitrary designation, and anyone who puts their focus on that arbitrary day is guilty of breaking some religious rule or other,no doubt!

the end says why it matters

We were never meant to celebrate the "day" just the event, just like his birth. This is where everybody gets it wrong. Jesus is eternal like God the Father, so the time,(day) his incarnation,(birth) as a human is of little importance, the same goes for his death. The only importance is that He came and fulfilled his Mission of Salvation.

then why do it on the holy day of the sabbath if it did not mean anything?

They don't embrace it because they love their traditions and not the truth Jesus dealt with this himself after miracles that he did and they still rejected him that's why
