No, and a neutral reader also said as much.
The first 4 books of the N.T. are written for the Jews to explain that Jesus was the Jews Messiah and King.
I think you need to do some more study. Luke was a Gentile writing to "theophilus" which is a Greek name for "lover of God." Could have been a Greek person or a term that was generic for people who love God. John has an evangelistic focus and is directed toward Greek speaking audiences that he assumes many of which are unfamiliar with Jewish phrases and practices, as the following verses show clearly.
“He first found his own brother Simon and said to him, “We have found the Messiah” (which means Christ). He brought him to Jesus. Jesus looked at him and said, “You are Simon the son of John. You shall be called Cephas” (which means Peter).” (John 1:41–42, ESV)
“The Samaritan woman said to him, “How is it that you, a Jew, ask for a drink from me, a woman of Samaria?” (For Jews have no dealings with Samaritans.)” (John 4:9, ESV)
“Jesus said to her, “Mary.” She turned and said to him in Aramaic, “Rabboni!” (which means Teacher).” (John 20:16, ESV)
Why would John explain what "Messiah" means or "Rabboni" if he is writing to a bunch of Jews? Why would he have to explain that Jews have no dealings with Samaritans? Richard, I dont know where you get your information, or if you just come up with this yourself, but it is far far far from orthodox and void of a fairly basic understanding of the Biblical text itself.
God had a new plan of salvation base on the shed blood on the cross. The true purpose for Jesus' death on the cross. But that purpose was “hidden in God” and revealed to Paul on the road to Damascus by Jesus. (Eph 3:9)
God's plan of salvation was prepared for "all people" before the foundation of the world...both Jews and Greeks. Paul's "mystery" that he was sent to proclaim was not a different Gospel than Peter or James. The mystery Paul proclaimed was the same Gospel Peter preached but with a focus on reaching the Gentiles and the emphasis on how the cross abolished the dividing wall of hostility between Jew and Gentile (which you seem to want to reestablish by your emphasis on God showing distinctions and favoritism based on a person's genealogy).
“I went up because of a revelation and set before them (though privately before those who seemed influential) the gospel that I proclaim among the Gentiles, in order to make sure I was not running or had not run in vain.” (Galatians 2:2, ESV)
“And from those who seemed to be influential (what they were makes no difference to me; God shows no partiality)—those, I say, who seemed influential added nothing to me. On the contrary, when they saw that I had been entrusted with the gospel to the uncircumcised, just as Peter had been entrusted with the gospel to the circumcised (for he who worked through Peter for his apostolic ministry to the circumcised worked also through me for mine to the Gentiles), and when James and Cephas and John, who seemed to be pillars, perceived the grace that was given to me, they gave the right hand of fellowship to Barnabas and me, that we should go to the Gentiles and they to the circumcised. Only, they asked us to remember the poor, the very thing I was eager to do.” (Galatians 2:6–10, ESV)
Please read carefully the above verses. This shows, beyond a shadow of doubt, that that 1. God shows no partiality (even with the Apostles), 2. they both preached the same Gospel but had different audiences, 3. Peter and James' message was not contrary to Paul's. Rather, they gave Paul "the right hand of fellowship."
The passages here in Galatians make it very clear that Paul received his message from God, but he still went to the other Apostles to confirm that he was preaching the same Gospel and that he wasn't "running in vain." After speaking to these influential men (and Paul makes it clear that his message was not changed by their influence because Paul wasnt concerned about pleasing men, but only God) it was confirmed that they were preaching the same Gospel and that Paul should focus his message on the Gentiles and Peter, James and John would focus on reaching the Jews. There is NOTHING here about two gospels, two plans of salvation or anything close to the idea that James and Paul were at odds in their messages. Nope, same Gospel, different audiences. I dont think these passages could be any more plain.
