You are ordinarily rational, but this has got to be the silliest thing you've ever written.
The anticipated Mass is not dispensing with anything. It extends the opportunity for fulfillment.
Does attending the Easter Vigil satisfy the Easter Sunday obligation? It always has, even in the pre-Vatican II days, when we celebrated the ceremony at 8:00.
The third commandment was given to the Jewish people, who celebrate it on Friday, into Saturday. Are they violating the third commandment as it was given to them?
I do not question the sincerity of the Jewish people in believing that the Old Covenant continues.
But Christ established the New Covenant, which in fulfilling the Old Covenant also extinguished it.
The New Covenant moved the Sabbath to Sunday. The Old Law must now be read in light of the New Covenant.
Never has, never will. Easter is on Sunday, not on Saturday. You are obliged to attend an Easter Mass which can start no sooner than 12:00 AM on Easter Sunday.
