There is only ONE gospel, defined in
1 Cor. 15:1-11, it's all about the resurrection of Christ.
That is not the gospel, but only a brief reference to Christ Jesus and his death, burial and resurrection for the atonement of sins. To reconcile us back to God our Father.
Paul is only addressing the doctrinal confusion in the Pentecostal Corinthian ekklesia about the resurrection of the dead.
The FULL gospel of salvation is much more extensive in doctrine and commandments that need to be believed and enacted upon.
John 3:3 Jesus answered and said to him, Amen, Amen, I say unto thee, Except one be born from above, he
cannot see the kingdom of God.
4 Nicodemus saith unto him, How can a man be born being an old man? can he enter a second time into the womb of his mother, and be born?
5 Jesus answered, Amen, Amen, I say unto thee,
Except one be born of water and Spirit, he cannot enter into the kingdom of God.
6 What is born of the flesh is flesh; and what is born of the Spirit is spirit.
7 Marvel not that I said to thee,
Ye must be born from above.
8 The Spirit breatheth where he willeth, and thou hearest his voice, but knowest not whence he cometh, and whither he goeth: so is everyone born of the Spirit.
Mark 16:15 And he said to them, Go into all the world, and
preach the gospel to the whole creation.
16
Who hath believed and is baptized shall be saved; but who hath disbelieved shall be condemned.
17
And these signs shall follow them that have believed: in my name shall they cast out demons, speak with tongues;
18 and in their hands they shall take up serpents, and if they drink aught deadly, it shall in now wise hurt them; they shall lay hands on the sick, and they shall recover.
19 So then the Lord Jesus, after he had spoken to them, was taken up into heaven, and sat down at the right hand of God.
20 And THEY went forth,
and preached everywhere, the Lord working with them, and
confirming the word by the signs that followed.
Acts 2:37 Now when they heard this, they were pricked in their heart, and said unto Peter and the rest of the apostles, [Men]
Brethren, what shall we do?
38 And Peter said unto them,
Repent and be
baptized each of you in the name of Jesus Christ unto
remission of your sins; and ye shall
receive the gift of the Holy Spirit.
39 For to you is the promise, and to your children, and to all that are afar off, as many as the Lord our God shall call unto him.
40 And with many other words he testified, and exhorted them, saying, Be saved from this crooked generation.
41 They then that received his word were baptized: and in that day were added about three thousand souls.
Romans 15:18 For I dare not speak aught save the things which Christ wrought through me, for obedience of the nations, by word or deed,
19 in
power of signs and wonders, in power of the Holy Spirit; so that from Jerusalem, and round about even unto Illyricum, I have fully preached the gospel of the Christ;
Galatians 1:11 But I make known to you, brethren, as to
the gospel which was preached by me,
that it is not after man.
12 For neither did I receive it from man, nor was I taught it,
but through revelation of Jesus Christ.
Jude 1:20 But ye, beloved, building up yourselves on your most holy faith,
praying in the Holy Spirit, [that is praying in tongues]
21 keep yourselves in God’s love, looking for the mercy of our Lord Jesus Christ unto eternal life.
