The same Gospel !
Many in false religion would tell us that Paul and Peter preached a different Gospel, one for the jews [Peter] and one for the Gentiles [Paul], but that is a absolute lie, in fact, that Paul Preached the same Gospel to both jew and Gentile alike is seen from Rom 1:16
16 For I am not ashamed of the gospel of Christ: for it is the power of God unto salvation to every one that believeth; to the Jew first, and also to the Greek.
In the greek it reads τὸ εὐαγγέλιον The Gospel with the definite article, its the one and only Gospel !
It appears to be True by the reading of 1 Cor 1:11-17
11 For it hath been declared unto me of you, my brethren, by them which are of the house of Chloe, that there are contentions among you.
12 Now this I say, that every one of you saith, I am of Paul; and I of Apollos; and I of Cephas; and I of Christ.
13 Is Christ divided? was Paul crucified for you? or were ye baptized in the name of Paul?
14 I thank God that I baptized none of you, but Crispus and Gaius;
15 Lest any should say that I had baptized in mine own name.
16 And I baptized also the household of Stephanas: besides, I know not whether I baptized any other.
17 For Christ sent me not to baptize, but to preach the gospel: not with wisdom of words, lest the cross of Christ should be made of none effect.
It also appears to be True from a reading of 1 Cor 3:4-5
4 For while one saith, I am of Paul; and another, I am of Apollos; are ye not carnal?
5 Who then is Paul, and who is Apollos, but ministers by whom ye believed, even as the Lord gave to every man?
6 I have planted, Apollos watered; but God gave the increase.
Paul, Cephas and Apollos are all ministers by which the Corinthian Believers believed by their Preaching of the same Gospel !
Paul and Peter had Fellowship in the same Gospel Gal 2:8-10
8 (For he that wrought effectually in Peter to the apostleship of the circumcision, the same was mighty in me toward the Gentiles )
9 And when James, Cephas, and John, who seemed to be pillars, perceived the grace that was given unto me, they gave to me and Barnabas the right hands of fellowship; that we should go unto the heathen, and they unto the circumcision.
10 Only they would that we should remember the poor; the same which I also was forward to do.
Fellowship meant agreement 2 Cor 6:14-16
14 Be ye not unequally yoked together with unbelievers: for what fellowship hath righteousness with unrighteousness? and what communion hath light with darkness?
15 And what concord hath Christ with Belial? or what part hath he that believeth with an infidel?
16 And what agreement hath the temple of God with idols? for ye are the temple of the living God; as God hath said, I will dwell in them, and walk in them; and I will be their God, and they shall be my people.
Phil 1:5
For your fellowship in the gospel from the first day until now;
Remember when Paul reproved Peter ? What was it for ?
Gal 2:14
But when I saw that they walked not uprightly according to the truth of the gospel, I said unto Peter before them all, If thou, being a Jew, livest after the manner of Gentiles, and not as do the Jews, why compellest thou the Gentiles to live as do the Jews?
Evidently they believed and Preached the same Gospel, and Paul rebuked Peter for not walking uprightly concerning it in a particular matter !
For both Paul and Peter were Apostles for the Body of Christ where there is no racial division in the things of God Eph 4:11-12
11 And he gave some, apostles[Paul and Peter]; and some, prophets; and some, evangelists; and some, pastors and teachers;
12 For the perfecting of the saints, for the work of the ministry, for the edifying of the body of Christ:
Yet carnal false believers would have the Body of Christ divided in a racial sense, inspite of Gal 3:26-28
26 For ye are all the children of God by faith in Christ Jesus.
27 For as many of you as have been baptized into Christ have put on Christ.
28 There is neither Jew nor Greek, there is neither bond nor free, there is neither male nor female: for ye are all one in Christ Jesus.
And they ignorantly and foolishly tell us that Paul and Peter preached Two different Gospels, based upon the flesh, ethnicity, race, yet nothing is further away from the Truth !
