I've been sort of waiting for you to say something like this..
Romans 2:16 in the day when God will judge the secrets of men by Jesus Christ, according to my gospel.
Romans 16:25 Now to Him who is able to establish you according to my gospel and the preaching of Jesus Christ, according to the revelation of the mystery kept secret since the world began
2 Timothy 2:8 Remember that Jesus Christ, of the seed of David, was raised from the dead according to my gospel,
Ephesians 3:2 if indeed you have heard of the dispensation of the grace of God which was given to me for you,
Galatians 2:7 But on the contrary, when they saw that the gospel for the uncircumcised had been committed to me, as the gospel for the circumcised was to Peter
1 Corinthians 4:16 Therefore I urge you, imitate me.
1 Corinthians 11:1 Imitate me, just as I also imitate Christ.
There are other such passages but that'll be sufficient to establish the point.
Huh? Without the epistles?
Well, lets see, without the epistles...
That means Acts only.
In Acts you have:
The Twelve receiving the Holy Spirit in continued fulfillment of Jewish prophesy.
Peter preaching and converting 3000 people.
Stephen showing the Jews with "irresistible wisdom" (a sign of the end times) that Jesus was their Messiah.
The Jews officially rejecting Jesus as the Messiah with the execution of Stephen after which he saw Jesus standing in heaven (standing usually preceding the pronouncement of judgment)
The first person Divine conversion of Saul.
Peter all but physically forced by God to kill and eat unclean animals.
Paul preaching first to the Jews
The Jews rejecting the message.
Paul turning instead to the Gentiles.
The books of Acts is all about the transition from the Peter and the Twelve (i.e. Israel) to Paul and the Gentiles. And I'd say that Peter's being made to eat unclean foods is a really good indication that something had changed. Something that wasn't intuitively understood by Peter, don't you agree?
Further, Peter and the Twelve were believers and Paul explicitly stated that God had not cut them when He cut off Israel as a nation, so where is the need for Paul? Where is the need to give Paul the gospel by revelation and send him (a Jew just like Peter and the Twelve) to the Gentiles if it was the same gospel?
Do you see my point?
There is no need for Acts if Paul's message was the same. There's no need for Paul at all for that matter. He could just as easily (perhaps more easily) have been converted in a normal way and been a convert like all the other converts and still been a leader and an evangelist. There just no need for all the fireworks and drama.
That cannot and did not preach the same thing!
Why do you keep asking me this? You don't get to just ignore the epistles.
I don't think it is possible to establish such a thing without the epistles beyond what I just got through explaining.
Why would you want to do so? What possible motive could you have to want to avoid the epistles in asking such a question as "What is the gospel?"
The book of Acts is not about the gospel, at least not directly. It's purpose is not to present the gospel but to present a history of the transition away from the Twelve and Israel and to Paul and the gentiles. A history that is critical to the acceptance of Paul as a legitimate Apostle which only makes sense if Paul's message was substantially different than that of Peter and the Twelve.
Resting in Him,
