There is no "Peter's gospel" in the NT.
Yours is not orthodox Christianity.
"
Orthodox definition is - conforming to established doctrine especially in religion."
Matthew 7:28 And it came to pass, when Jesus had ended these sayings, the people were astonished at
His doctrine: 29 For He taught them as [one] having authority, and not as the scribes.
The Gospel of the Kingdom
Matthew 24:14 And
this Gospel of the Kingdom shall be preached in all the world for a witness unto all nations; and then shall the end come. 26:13 Verily I say unto you, Wheresoever
this Gospel shall be preached in the whole world, shall also this, that this woman hath done, be told for a memorial of her.
Matthew 28:16-20
Teaching them to observe all things whatsoever I have commanded you
1 Peter 4:17-18 For the time [is come] that judgment must begin at the house of God: and if [it] first [begin] at us, what shall the end [be] of
them that obey not the Gospel of God? 18 And if the righteous scarcely be saved, where shall the ungodly and the sinner appear?
1 Peter 1:23 Being
born again, not of corruptible seed, but of incorruptible, by
the word of God, which liveth and abideth for ever. 24 For all flesh [is] as grass, and all the glory of man as the flower of grass. The grass withereth, and the flower thereof falleth away: 25 But the word of the Lord endureth for ever. And this is the word which by the gospel is preached unto you. (Esaias 40:3, John 1:23)
James 1:18 Of His own will
begat He us with the word of truth, that we should be a kind of firstfruits of his creatures.
John 17:17 Sanctify them through Thy truth:
Thy word is Truth.
John 16:2 They shall put you out of the synagogues: yea, the time cometh, that whosoever killeth you will think that he doeth God service. 16:27 For
the Father himself loveth you, because ye have loved Me, and have believed that I came out from God.
John John 15:3 Now ye are
clean through the word which I have spoken unto you. 15:7
If ye abide in Me, and
My words abide in you, ye shall ask what ye will, and it shall be done unto you.
John 14:15-17
If ye love Me, keep My commandments.
And I will pray the Father, and He shall give you another Comforter, that He may abide with you for ever; the Spirit of truth; whom the world cannot receive, because it seeth Him not, neither knoweth Him: but ye know Him; for He dwelleth with you, and shall be in you.
John 13:35 By this shall all [men] know that ye are
My Disciples, if ye have love one to another.
John 12:44 Jesus cried and said,
He that believeth on Me, believeth not on Me, but on Him that sent Me. 45 And he that seeth Me seeth Him that sent Me. 46 I am come a light into the world, that whosoever believeth on Me should not abide in darkness. 47 And if any man hear My words, and believe not, I judge him not: for I came not to judge the world, but to save the world. 48 He that rejecteth Me, and receiveth not My words, hath one that judgeth him: the word that I have spoken, the same shall judge him in the last day. 49 For I have not spoken of Myself; but the Father which sent Me, He gave Me a commandment, what I should say, and what I should speak. 50 And I know that
His Commandment is Life Everlasting: whatsoever I speak therefore, even as the Father said unto Me, so I speak.
Begotten by the word of truth. This is the Gospel of the Kingdom.
