Using scripture, not just your opinion, would you please tell me why you believe that the resurrection of our Lord occurred on the 7th day Sabbath rather than on the day following the 7th day Sabbath, the day of First Fruits?
Two basic and proving reasons.
One)
The Old Testament never speaks about the Sabbath for the sake of the Sabbath per se (like it never speaks about anything for its own sake). The Old Testament whenever it speaks about the Sabbath, does so with The Word, Jesus Christ, in view and as the end-goal and reach, of its proclamation -- no different than with anything else the Old Testament may speak about.
Old and New Testaments declare the perfectly identical Divine Truth about the Sabbath.
From the Old, "the day The Seventh Day Sabbath Rest Day : OF THE LORD GOD";
From the New, "God thus concerning the Seventh Day spake, And God the day, The Seventh Day, from all his works rested."
This is telling us why to believe that the Resurrection of our Lord occurred on <the 7th Day Sabbath> -- because Jesus' resurrection "made the Sabbath", "The Lord's Day" about which "God, thus concerning the Seventh Day ... through the prophets in times past ... spake."
Two)
The NEW Testament never speaks about the Sabbath for the sake of the Sabbath per se (like it never speaks about anything for its own sake). The New Testament whenever it speaks about the Sabbath, does so with The Word, Jesus Christ, in view and as the end-goal and reach of its proclamation -- no different than with anything else the New or the Old Testament may speak about.
Several declarations from the New Testament proclaim this perfectly fulfilled Divine Truth about the Sabbath of God’s Rest which He rested in Christ in his Resurrection. Ephesians 1:19-24, “the all-exceeding reach and goal of the working of God’s Mighty Power which He WROUGHT WHEN HE RAISED CHRIST FROM THE DEAD” – the most powerful and august definition of God’s ultimate Rest in Christ in resurrection from the dead in all of the Holy Scriptures.
This is telling us why to believe that the Resurrection of our Lord occurred on <<the 7th Day Sabbath>>, because Jesus' resurrection "made the Sabbath", "The Lord's Day"— day of which "God, thus concerning the Seventh Day ... in these last day … BY THE SON, spake."
“If JESUS gave them rest— [“the Rest of God” - Katapausis tou Theou], there THEREFORE for the People of God remains a keeping of the Sabbath Day [sabbatismos] : HE, having ENTERED into his own Rest as God in his Own”. “GOD RAISED UP CHRIST from the dead BY THE GLORY OF THE FATHER” which glory of the Father is the Rest of God IN CHRIST JESUS.
God’s Glorious Rest from all his works WROUGHT and finished, came together and culminated in Christ “when God RAISED Him from the dead”. Ephesians 1:19.
So in Exodus 15 “The Lord TRIUMPHED GREATLY” when the LORD “brought” Israel “up, out” of the sea-grave ON THE SABBATH— wherefore the LORD commanded them to “remember the Sabbath Day”, and “they sang a New Song … the Song of Moses and of the Lamb” the Lord’s Sabbaths’ Song of Victory in his Rest through Jesus Christ.
“The Lamb stood on the mountain as slain”, Resurrected from the dead. “The Lamb stood on the mountain as slain” IN HIS GLORY—the glory of His Sabbath Day’s Victory— victory “on the Lord’s Day”! “And with Him stood hundred and forty four thousand redeemed from the earth”, that is, resurrected from the dead. The Sabbath was the day “the LORD planted them in the Mountain of his Inheritance”; his—Christ’s, “Inheritance in the saints” the Church triumphant. Ephesians 1:18.
