Yes. The resurrection could have taken place on a Saturday night. But don't miss the key element here.
Worship is celebration. And the celebration of Jesus' resurrection originally took place on a Sunday -- the day of discovery and the revelation of the Resurrected One. Jesus Himself marks the new beginning, just as the first day of a new week marks the new beginning.
That's certainly a post biblical traditional view. Nobody in biblical times thought it wise to overthrow the Lord's sabbaths and institute man made ones. <
Earlier you referred to the Lord's sabbath as the "Jewish " sabbath. While true that some Jews observe the Lord's sabbath, it's not true that it's the Jew's sabbath.
Lev 23:3 'Six days shall work be done, but the seventh day is a Sabbath of solemn rest, a holy convocation. You shall do no work on it; it is the Sabbath of the LORD in all your dwellings.
Exo 20:8 "Remember the Sabbath day, to keep it holy.
Exo 20:9 Six days you shall labor and do all your work,
Exo 20:10 but the seventh day is the Sabbath of the LORD your God. In it you shall do no work: you, nor your son, nor your daughter, nor your male servant, nor your female servant, nor your cattle, nor your stranger who is within your gates.
So the Lord, Jesus Christ, declared his sabbath long ago. The Lord, Jesus Christ, kept his sabbath. Christians, those who follow Christ, should likewise honor the Lord by honoring His sabbath.
