I think that what is the most foolish is the idea that none of the Bible can be trusted to be right if it is not considered to be all true and right.
They have to believe that every word should be what God says for any of it to be what God says.
You got it. The false gospel Paul speaks of in Galatians is the one the orthodox teaches. Combining the Jews ideology with the Gospel Paul was teaching.
Galatians 1:
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.
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.
It's clear that the Gospel Paul was teaching did not come from the OT in any way (as he continues to say in the next 5 chapters, refuting the law and circumcision).
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:
It fits just like the post I made above this one of antichrist. The emerging catholic ideology used the OT to distort the Gospel Paul was teaching. Simply, the importance of flesh and blood.
Paul continues to accuse Peter of this gospel, siding with the Pharisee's, who sought (fleshly) power:
Galatians 2 :
11 But when
Peter was come to Antioch, I withstood him to the face, because he
was to be blamed.
12 For before that certain came from James, he did eat with the Gentiles: but when they were come, he withdrew and separated himself, fearing them which were of the circumcision.
13 And the other Jews dissembled likewise with him; insomuch that Barnabas also was carried away with their dissimulation.
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?
15 We who are Jews by nature, and not sinners of the Gentiles,
16 Knowing that a man is not justified by the works of the law, but by the faith of Jesus Christ, even we have believed in Jesus Christ, that we might be justified by the faith of Christ, and not by the works of the law: for by the works of the law shall no flesh be justified.
Verse 12 has Paul saying that Peter "feared" the Jews. Peter was NO rock. Never was. He is blamed for allowing the gospel to be tainted by Jewish ideology. I side with Paul here.
