When did Peter do this, rinnie? Paul is emphatic in his epistles that the only one who revealed anything to him was Christ and Christ alone.
You mean where St. Paul says that he didn’t receive the gospel from men?
Ga 1:11 For I would have you know, brethren, that the gospel which was preached by me is not man’s gospel.
12 For I did not receive it from man, nor was I taught it, but it came through a revelation of Jesus Christ.
Read on.
He goes on to say that he verified his teaching first with St. Peter, then with the Church leaders (Peter, John, & James):
Ga 1:15 But when he who had set me apart before I was born, and had called me through his grace,
16 was pleased to reveal his Son to me, in order that I might preach him among the Gentiles, I did not confer with flesh and blood,
17 nor did I go up to Jerusalem to those who were apostles before me, but I went away into Arabia; and again I returned to Damascus.
18 Then after three years I went up to Jerusalem to visit Cephas, and remained with him fifteen days.
Ga 2:2 I went up by revelation; and I laid before them (but privately before those who were of repute) the gospel which I preach among the Gentiles, lest somehow I should be running or had run in vain.
Which leaders? “those who were of repute”
He tells us who they were in a few verses:
Ga 2:9 and when they perceived the grace that was given to me, James and Cephas and John, …
Yes, he says in verse 6 that they “added nothing to me”, but that just means that Paul’s version of the Gospel had been vindicated by Peter, John, and James. In other words, St. Paul got the confirmation that he wanted, no needed, from the Apostles “lest somehow [he] should be running or had run in vain.”
