Huge assumption with no direct biblical evidence. Yes he taught against circ to the gentiles; but do you have evidence that was what he taught to the Jewish believers?
BTW, Acts 21 is fairly clear that the 2 groups did not have the same teaching
I guess you live for dispute.
For Gentiles to beware of that concision ( circumcision of the flesh people) because we ( Gentiles including Apostle Paul the Apostle to the Gentiles Romans 11:13. are the circumcision which worship God in the Spirit ( having no confidence in the flesh, as they who are of flesh circumcision must still have)
Paul shows he could have that confidence in the flesh, as he had previously been a perfect example of a Jew in the flesh and zealous of the same law ( confidence in the flesh)
Then Paul shows the path for the Jew, is to lose all of that, to lose all things for the knowledge of Christ ( to now worship in the Spirit)
No longer the law of self righteousness ( circumcision in the flesh to have glory of men, and stated they who are circumcised that way neither keep the law, so are hypocrites. As they are debtor to do the whole law but break it) and we know the faith of Christ, which is His resurrection. ( this is the circumcision made without hands)
It is also when there is no longer Jew nor Gentile, there is only the new creature or nothing at all, and then this is the circumcision of the heart, to put on Christ which is bowels of mercies and charity, the bond of perfectness.
Philippians 3: 2 Beware of dogs, beware of evil workers, beware of the concision.
3 For we are the circumcision, which worship God in the spirit, and rejoice in Christ Jesus, and have no confidence in the flesh.
4 Though I might also have confidence in the flesh. If any other man thinketh that he hath whereof he might trust in the flesh, I more:
5 Circumcised the eighth day, of the stock of Israel, of the tribe of Benjamin, an Hebrew of the Hebrews; as touching the law, a Pharisee;
6 Concerning zeal, persecuting the church; touching the righteousness which is in the law, blameless.
7 But what things were gain to me, those I counted loss for Christ.
8 Yea doubtless, and I count all things but loss for the excellency of the knowledge of Christ Jesus my Lord: for whom I have suffered the loss of all things, and do count them but dung, that I may win Christ,
9 And be found in him, not having mine own righteousness, which is of the law, but that which is through the faith of Christ, the righteousness which is of God by faith:
10 That I may know him, and the power of his resurrection, and the fellowship of his sufferings, being made conformable unto his death;
11 If by any means I might attain unto the resurrection of the dead.
Galatians 5:3 For I testify again to every man that is circumcised, that he is a
debtor to do the whole
law.
Galatians 6:13 For neither they themselves who are circumcised keep the law; but desire to have you circumcised, that they may
glory in your
flesh.
Colossians 2:11 In whom also ye are circumcised with the
circumcision made without
hands, in putting off the body of the sins of the flesh by the
circumcision of Christ:
Colossians 3:9 Lie not one to another, seeing that ye have put off the old man with his deeds;
10 And have put on the new man, which is renewed in knowledge after the image of him that created him:
11 Where there is neither Greek nor Jew, circumcision nor uncircumcision, Barbarian, Scythian, bond nor free: but Christ is all, and in all.
12 Put on therefore, as the elect of God, holy and beloved, bowels of mercies, kindness, humbleness of mind, meekness, longsuffering;
13 Forbearing one another, and forgiving one another, if any man have a quarrel against any: even as Christ forgave you, so also do ye.
14 And above all these things put on charity, which is the bond of perfectness.
