Try this: Peter does not preach Paul, Paul does not preach John, John does not preach Peter.
There are rules about preaching the Gospel in the New Testament that define content and what is to be our source material. I will provide some verses I have worked on regarding this. (This is a copy and paste)
1John1:1-3 “That which was from the beginning, which we have heard, which we have seen with our eyes, which we have looked upon, and our hands have handled, of the Word of life; For the life was manifested, and we have seen it, and bear witness, and shew unto you that eternal life, which was with the Father, and was manifested unto us; That which we have seen and heard declare we unto you.
I spoke before of this personal testimony, this personal experience of the acts of God as being a law that Isaiah did not preach Jeremiah and Jeremiah did not speak Ezekiel each spoke only that which they saw and heard likewise Paul does not preach peter peter does not preach John and John does not preach paul.
John 3:11 “Verily, verily, I say unto thee, we speak that we do know, and testify that we have seen . . .” The Greek reads Verily Verily I say unto thee, That which we know (Oidamen to know by having asked – to know by having examined) we speak, and that which we have seen we bear witness of.
Acts 4:20 For we cannot but speak the things which we have seen and heard.
Now if this point were not important it would not be repeated again and again but it has somehow slipped under the church’s radar screen like most things that pertain to life and godliness, glory and virtue.
Matthew 11:4 Jesus answered and said unto them, Go and shew John again those things which ye do hear and see: Here we catch Jesus commanding the disciples of John to speak only that which they have seen and heard.
Romans 15:18-20 For I will not dare to speak of any of those things which Christ hath not wrought by me, to make the Gentiles obedient, by word and deed, Through mighty signs and wonders, by the power of the Spirit of God; so that from Jerusalem, and round about unto Illyricum, I have fully preached the gospel of Christ.
Why does Paul the Apostle say that he dare not? The dare not implies that if Paul would speak of what Christ did in others, or preached what Christ had taught others there would be unwelcome consequences – ie no mighty signs and wonders no power of the spirit of God – So in his ministry Paul says by preaching what God wrought in Paul and what Christ taught Paul he was fully preaching the Gospel – Because the Gospel is what God has wrought in you and taught you.
Hebrews 2:3-5 How shall we escape, if we neglect so great salvation; which at the first began to be spoken by the Lord, and was confirmed unto us by them that heard him; God also bearing them witness, both with signs and wonders, and with divers miracles, and gifts of the Holy Ghost, according to his own will?
