Why do the 4 Gospels correlate so well?
It could be that all 4 writers got the same narrative from Paul himself.
All four Gospels were written by 4 of the 12 that were with Jesus during His earthly ministry. Paul definitely would not have been with them in the years following in which they wrote the Gospels. He was still 'out to destroy' all followers of Jesus per Acts 8:1 above. Nor did Paul consult with the 11 to develop the 'his' Gospel in 1 Corinthians 15:1-4. Paul wrote that sometime after Jesus met him on the road to Damascus, he went to Arabia (some conjecture it might be Mt Sinai, which would make sense) and he spent 3 years being instructed by Jesus Himself
Galatians 1:11-18 (KJV)
11
But I certify you, brethren, that the gospel which was preached of me is not after man.
12
For I neither received it of man, neither was I taught it, but by the revelation of Jesus Christ.
13
For ye have heard of my conversation in time past in the Jews' religion, how that beyond measure I persecuted the church of God, and wasted it:
14
And profited in the Jews' religion above many my equals in mine own nation, being more exceedingly zealous of the traditions of my fathers.
15
But when it pleased God, who separated me from my mother's womb, and called me by his grace,
16
To reveal his Son in me, that I might preach him among the heathen; immediately I conferred not with flesh and blood:
17
Neither went I up to Jerusalem to them which were apostles before me; but I went into Arabia, and returned again unto Damascus.
18
Then after three years I went up to Jerusalem to see Peter, and abode with him fifteen days.
Note that verse 18 does not refer to the Jerusalem council...that was sometime later. Did Peter go to Cornelius' house before or after verse 18? I don't know. But it DID happen before the Jerusalem council as Peter defended Paul's assertion that Gentiles received the Holy Spirit. He was a personal witness to the fact at Cornelius' house. Perhaps THAT was why God led Peter there in the first place...his later testimony at the Jerusalem council.
Doesn't make it any less true or verifiable. It's just the translation or interpretation of what was transpiring at the time.
I believe the Gospel, but whose Gospel is it?
...
Paul wasn't trying to create a new religion. He was turning the OT inside out so we could see the deeper meaning hidden like treasure.
There were some things that Paul hadn't fully grasped yet, like looking through a glass darkly. There is still much more learning to do.
Paul wasn't turning the Old Testament inside out. He was presenting that which was hidden from the beginning of time by God ('mysteries' in Pauls writings) until given to him by Jesus while in Arabia -
Deuteronomy 29:29
The secret things belong unto the LORD our God: but those things which are revealed belong unto us and to our children for ever, that we may do all the words of this law.
Romans 16:25 (KJV)
25 Now to him that is of power to stablish you according to my gospel, and the preaching of Jesus Christ, according to the revelation of the mystery, which was kept secret since the world began,
26 But now is made manifest, and by the scriptures of the prophets, according to the commandment of the everlasting God, made known to all nations for the obedience of faith:
27 To God only wise, be glory through Jesus Christ for ever. Amen (underlining mine)
The Gospel given to Paul, which he referred to as 'my gospel', was directly from Jesus. Yes, it is a different Gospel (the coming kingdom) that Jesus spoke of several times: (all KJV)
Matthew 4:23
And Jesus went about all Galilee, teaching in their synagogues, and preaching the gospel of the kingdom, and healing all manner of sickness and all manner of disease among the people.
Matthew 9:35
And Jesus went about all the cities and villages, teaching in their synagogues, and preaching the gospel of the kingdom, and healing every sickness and every disease among the people.
Matthew 24:14
And this gospel of the kingdom shall be preached in all the world for a witness unto all nations; and then shall the end come.
Mark 1:14-15
Now after that John was put in prison, Jesus came into Galilee, preaching the gospel of the kingdom of God,
15
And saying, The time is fulfilled, and the kingdom of God is at hand: repent ye, and believe the gospel.
I'll throw in Pauls statement about Jesus going to Jews only -
Rom 15:8
Now I say that Jesus Christ was a minister of the circumcision for the truth of God, to confirm the promises made unto the fathers: (KJV)
Compare that to Pauls' Gospel -
1Co 15:1-4 (KJV)
1
Moreover, brethren, I declare unto you the gospel which I preached unto you, which also ye have received, and wherein ye stand;
2
By which also ye are saved, if ye keep in memory what I preached unto you, unless ye have believed in vain.
3
For I delivered unto you first of all that which I also received, how that Christ died for our sins according to the scriptures;
4
And that he was buried, and that he rose again the third day according to the scriptures:
All of OT prophecy talked about the coming kingdom with the Messiah as its king. Jesus was that promised Messiah. He preached the Gospel of the kingdom to Israel and that He was the Messiah/king. That's why the Pharisees hated him so much...a carpenters' son, king? Israel knew there'd be a kingdom, but that the 7 years tribulation would be first. That's why, even today, Israel is still awaiting the Messiah after the tribulation. Even moments before His ascension, the disciples were expecting the kingdom any day now:
Acts 1:6
When they therefore were come together, they asked of him, saying, Lord, wilt thou at this time restore again the kingdom to Israel? (KJV)
Many consider, as do I, that the stoning of Stephen was the ultimate and final denial of Jesus by Israel. The Gospel of the Kingdom has became officially 'delayed' or 'set aside' for a while....almost 2000 years and counting. God allowed that Gospel to continue and the 12 still preaching it and that Jesus was the promised Messiah. But at the destruction of the temple in 70 AD occurred, it was all of Israel that was set aside until the 1948 re-creation, just like Ezekiel prophesied about the dried bones.
So, at the stoning of Stephen, God turned to the Gentiles and brought in Saul. Saul went on his way persecuting all that believed in Jesus as the Messiah wherever he could find them. It was only a couple years later that Jesus met him on the road to Damascus, and he changed from persecution to proclaiming that Jesus IS the Messiah in synagogues wherever he went. Those that knew of him were completely afraid because they knew of his persecuting believers. It was only some years later that he was led by the spirit into Arabia and taught by Jesus. As noted in Galatians 1 above, Paul did NOT go confer with the apostles to get the 'scoop' on how to go to the Gentiles. Paul was Gods' chosen apostle to the Gentiles. The disciples remained apostles to Jews only, and confirmed at the Jerusalem council likely about 55 AD.
Pauls' Gospel, aka, 'my Gospel' is the Gospel of Grace (1 Corinthians 15:1-4). It was to Paul alone that God presented salvation by grace through faith alone. Paul emphasized that over and over throughout his letters, even his letter to the Hebrews. There isn't a HINT in any of the 4 Gospels about Jesus' death for their sins. Like Peter, Israel needed only to believe that Jesus was the Messiah. Period. Nothing about Jesus' death for their sins.
Matthew 16:13-16(KJV)
13
When Jesus came into the coasts of Caesarea Philippi, he asked his disciples, saying, Whom do men say that I the Son of man am?
14
And they said, Some say that thou art John the Baptist: some, Elias; and others, Jeremias, or one of the prophets.
15
He saith unto them, But whom say ye that I am?
16
And Simon Peter answered and said, Thou art the Christ, the Son of the living God.
Paul also had to defend 'his' Gospel against those that would add to it, such as the Judaisers that came after he had left the churches of Gentile believers in the Gospel of Grace. Most notably as noted in his letter to Galatia some years after he left there -
Galatians 1:6-10 (KJV)
6
I marvel that ye are so soon removed from him that called you into the grace of Christ unto another gospel:
7
Which is not another; but there be some that trouble you, and would pervert the gospel of Christ.
8
But though we, or an angel from heaven, preach any other gospel unto you than that which we have preached unto you, let him be accursed.
9
As we said before, so say I now again, If any man preach any other gospel unto you than that ye have received, let him be accursed.
10
For do I now persuade men, or God? or do I seek to please men? for if I yet pleased men, I should not be the servant of Christ.
The Judaisers were telling the Galatians that they had to become Jews to fully accept Jesus, ie, putting them under the law including Kosher food, and, of course, male circumcision. Work, work, work, keep the law, and on and on. The Judaisers were ADDING to the simplicity that is the Gospel of Grace.
Perhaps the biggest obstacle to believing the Gospel of Grace in 1 Corinthians 15:1-4 is how simple it is. No extra 'do this, do that, eat this, eat that, believe this too', etc. Simply believe the Gospel in your heart. Period. aka, KISS.
Ephesians 2:8-9 (KJV)
8
For by grace are ye saved through faith; and that not of yourselves: it is the gift of God:
9
Not of works, lest any man should boast.
