1 Corinthians 2:2
For I determined to know nothing among you except Jesus Christ, and Him crucified.”
So because of that verse he didn’t know about the resurrection ? Or the ascention or the doctrine ?
“God forbid. How shall
we, that are dead to sin, live any longer therein?
Know ye not, that so many of us as were baptized into Jesus Christ were baptized into his death? Therefore we are buried with him by baptism into death: that like as
Christ was raised up from the dead by the glory of the Father, even so we also should walk in
newness of life. For if
we have been planted together in the likeness of his death, we shall be also in the likeness of his
resurrection:
knowing this, that our old man is crucified with him, that the body of sin might be destroyed, that henceforth we should not serve sin. For
he that is dead is freed from sin.
Likewise
reckon ye also yourselves to be dead indeed unto sin, but alive unto God through Jesus Christ our Lord.”
Romans 6:2-7, 11 KJV
most of what Paul taught revolves around Jesus death and resurrection but most of it is applicable to us in doctrines like
baptism for remission of sins in his name .
That only matters because Jesus does for our sins and rose up again . Without that baptism means nothing . Paul taught about the same things Jesus did repeatedly eternal judgement based upon mens deeds , baptism for remission of sins , communion with the body and blood of Jesus
“For I have received of the Lord that which also I delivered unto you, That the Lord Jesus the same night in which he was betrayed took bread: and when he had given thanks, he brake it, and said, Take, eat: this is my body, which is broken for you: this do in remembrance of me. After the same manner also he took the cup, when he had supped, saying, This cup is the new testament in my blood: this do ye, as oft as ye drink it, in remembrance of me. For as often as ye eat this bread, and drink this cup, ye do shew the Lord's death till he come. Wherefore whosoever shall eat this bread, and drink this cup of the Lord, unworthily, shall be guilty of the body and blood of the Lord. But let a man examine himself, and so let him eat of that bread, and drink of that cup. For he that eateth and drinketh unworthily, eateth and drinketh damnation to himself, not discerning the Lord's body. For this cause many are weak and sickly among you, and many sleep.”
1 Corinthians 11:23-30 KJV
one verse out of context doesn’t change the rest of what’s written in Paul’s epistles . He preached a lot about Jesus death for our sins and resurrection for our justification he also taught and preach many more revelations to the church regarding many more subjects
