So the following words of Peter had nothing to do with the preaching of Jesus Christ according to the revelation of the mystery?:
"Forasmuch as ye know that ye were not redeemed with corruptible things, as silver and gold, from your vain conversation received by tradition from your fathers; But with the precious blood of Christ, as of a lamb without blemish and without spot" (1 Pet.1:18-19).
It is ever fascinating how often you expect agreement with one or another result of your various faulty premises, to begin with. :chuckle:
That passage is not talking about the Mystery.
The Cross is an Old Testament Prophecy (Isaiah 53; Daniel 9, for example) made reality at the Cross.
TWO-Fold Purpose in, by, at, and through The Cross, bro.
One Prophesied since the world began; One Kept Scret since the world began.
That Christ would die "for the transgressions of my people" was one aspect.
They were then to take that to the rest of said people towards their Prophesied Priesthood over the Nations of the Earth as a redeemed nation representative of the God of Israel.
Which was why He said the following as if obviously expecting they would know what He was talking about...
Mark 14:24 And he said unto them, THIS is my blood of THE new testament, which is shed for many.
Thus, His Words to those two in...
Luke 24:19 And he said unto them, What things? And they said unto him, Concerning Jesus of Nazareth, which was a prophet mighty in deed and word before God and all the people: 24:20 And how the chief priests and our rulers delivered him to be condemned to death, and have crucified him. 24:21 But we trusted that it had been he which should have redeemed Israel: and beside all this, to day is the third day since these things were done.
24:25 Then he said unto them, O fools, and slow of heart to believe all that the prophets have spoken: 24:26 Ought not Christ to have suffered these things, and to enter into his glory? 24:27 And beginning at Moses and all the prophets, he expounded unto them in all the scriptures the things concerning himself.
Deny it how some might, it is crystal clear obvious that He had expected them to believe that He would die and rise again, and that His death was the issue of "my blood of the new testament, which is shed for many."
"The many" at that stage in all that, being...
Isaiah 53:8 He was taken from prison and from judgment: and who shall declare his generation? for he was cut off out of the land of the living: for the transgression of my people was he stricken.
Daniel 9:26 And after threescore and two weeks shall Messiah be cut off, but not for himself...
That is NOT the Mystery of the Cross preached by Paul - rather, THAT is THEIR aspect of the finished work of the Cross - on THEIR behalf.
As I pointed out to you elsewhere to the same old usual "no avail" :chuckle: - after the Cross, they had remained under the Law, not for "that righteousness which is of the law" anymore, for they now had that in His finished work (Peter's and Hebrews' point) rather, they remained under the Law because it is there Identity, as His Peculiar People in the sight of the Nations.
You read into and cite the Circumcision Apostles all you want; they did NOT preach the Mystery of the Cross first and only preached by that seemingly odd, completely unexpected but by God, one Apostle too many to God's already called Israel's Twelve Apostles by the time of said seemingly odd; one Apostle too many: the Apostle of the Gentiles; the Apostle Paul.
Rom. 14: 5; 5:7,8
