Once gMark is accepted as the earliest Gospel in the Canon then it is imperative that it is clearly understood what was the earliest Good News.
gMark was written about the beginning of the Gospel of Jesus [the Good News of Jesus].
Sinaiticus gMark 1
The author of Sinaiticus gMark will explain the Good News of the supposed Jesus.1:1 The beginning of the gospel of Jesus Christ
Sinaiticus gMark 1
1.14 But after John was delivered up, Jesus came into Galilee, preaching the gospel of God,
15 that the time is fulfilled and the kingdom of God is at hand: Repent and believe in the gospel.
The earliest Good News was that the Kingdom of God is at hand--the time is fulfilled.
The earliest Good News is based on supposed prophecies about a new Jerusalem in the new earth.
Now, examine Isaiah 65.
Isaiah 65 NAS
17 "For behold, I create new heavens and a new earth ; And the former things will not be remembered or come to mind.
18 "But be glad and rejoice forever in what I create ; For behold, I create Jerusalem for rejoicing And her people for gladness.
19 "I will also rejoice in Jerusalem and be glad in My people ; And there will no longer be heard in her The voice of weeping and the sound of crying.
The earliest Gospel, the earliest Good News was the coming of the New Jerusalem.
gMark's Jesus did NOT want the Populace to be saved but to remain in sin.---See Mark 4
gMark's Jesus did not want the Populace to call him the Christ.---See Mark 7.34-36
The Pauline claim that Jesus Christ died for the Sins of mankind is a Late Gospel and is NOT the Good News of gMark's Jesus.
The Pauline claim that without the Resurrection mankind would remain in sin was a Late invention unknown to the author of gMark.
Mark 4
The earliest Gospel, the earliest Good News, gMark's Good News, had nothing whatsoever to do with salvation by sacrifice or the abolishment of the Laws of the Jews for sacrifice....... but unto them that are without, all these things are done in parables........ lest at any time they should be converted , and their sins should be forgiven them.
gMark's Good News predated the Pauline Gospels.
Galatians 2:20 KJV
The Markan Jesus never preached such Gospel.I am crucified with Christ: nevertheless I live ; yet not I, but Christ liveth in me: and the life which I now live in the flesh I live by the faith of the Son of God, who loved me, and gave himself for me.
The Markan Good News was that the Kingdom of God was near---the New Jerusalem at hand.
The Good News of the New Jerusalem found in Isaiah and gMark is also found in the Revelation of John.
Revelation 1 KJVV
The earliest Good News in the Canon is gMark's Good News--the coming of the New Jerusalem--the New Kingdom of God.1 And I saw a new heaven and a new earth: for the first heaven and the first earth were passed away ; and there was no more sea.
2 And I John saw the holy city, new Jerusalem, coming down from God out of heaven, prepared as a bride adorned for her husband.
3 And I heard a great voice out of heaven saying , Behold , the tabernacle of God is with men, and he will dwell with them, and they shall be his people, and God himself shall be with them, and be their God.
4 And God shall wipe away all tears from their eyes; and there shall be no more death, neither sorrow, nor crying, neither shall there be any more pain: for the former things are passed away .
God shall wipe away all tears from their eyes.
