Your view is that the Biblical writers were NOT being led by the Holy Spirit?
Here is what the Holy Spirit teaches..
= The bible is a spiritual book of : Progressive Revelation.
Its being revealed from Genesis, till the Millennium., and more.
During all this......God never changes, but He changes how he deals with Man.........all through the Bible, that is God's revelation.
For example.....In the OT.........you had no Cross of Christ.......but you had Moses Law..........However, Moses Law was not found in the Garden of Eden.
So, do you see those 3 differences?....... as God was doing something Different, in each case.
So, as the OT was transitioning into the NT, and the New Covenant.......God was revealing How He was setting the Jews aside, for a time.......to deal with the GENTILEs.
We are now in the """time of the Gentiles"""", and God is specifically dealing with the GENTILES......and not the Jews.
God will resume His dealing with the JEW, in the Trib......and we are not in it......we are "in the time of the Gentiles".
So, in the "time of the Gentiles"....that started with Jesus's Crucifixion....the "body of Christ" that is "the NT Church".....begain.
And there is only ONE Apostle who is the """"Apostle to the Gentiles"""...in "the Time of the Gentiles'.....so, His Doctrine.....and His Gospel, is OURS......., and that apostle is not Peter, or any of the original 11.
Its only PAUL.
So, when you see Peter, at the very beginning of the birth of the NT Church......right after Jesus is Risen.....and Peter is preaching "repent and be water baptized"....>>He is preaching the OLD Covenant, Old Testament message for the JEWS.
He is not speaking to the Gentiles.......and that is why we do not have "repent and get wet" as The Gospel that is Given by PAUL.
Paul teaches that "Christ sent me NOT to Water Baptise".....but to """preach The Cross""">.....that is the "Gospel of the Grace of God"......that is "Justification by faith"..and it has no water in it., as Paul is not preaching to the JEW........He's not preaching John the Baptist's "repent".. message.
Paul is preaching.....the Gospel of the GRACE of God that is....>>"All who call on the name of Jesus shall be saved"...
Paul is preaching....>>"not according to our works, but according to God's MERCY, He saved us"...not by water but by "GRACE through Faith".
A.) "Justificaton by Faith"...without works, or law keeping or water baptism.
Paul taught Peter and the other 11 Apostles
HIS "Gospel", about 15+yrs after Paul was sent by Jesuis to Preach : "Paul's Gospel".
And Paul's Gospel, as He explains in Galatians 1:8, is the ONLY Gospel, "in the time of the Gentiles".
