TCGreek said:
1. Before Paul wrote Chapter 15, he wrote Chps 1 and 2, where he "preached Christ crucified a stumbling block to Jews and foolishness to Gentiles" (1:23).
And he continues "For I resolved to know nothing while I was with you except Jesus Christ crucified" (2:2).
2. Did he preach the resurrection of Christ? Of course, he!
3. But he only mentioned the death of Christ, which of course, would include Christ resurrection.
1 Corinthians 1:10-13
10Now I beseech you, brethren, by the name of our Lord Jesus Christ, that ye all speak the same thing, and that there be no divisions among you; but that ye be perfectly joined together in the same mind and in the same judgment.
11For it hath been declared unto me of you, my brethren, by them which are of the house of Chloe, that there are contentions among you.
12N
ow this I say, that every one of you saith, I am of Paul; and I of Apollos; and I of Cephas; and I of Christ.

Is Christ divided? was Paul crucified for you? or were ye baptized in the name of Paul?
First of all the context of Chapter 1 is that the Corinthians were divided in their faith regarding of whom they were baptized. Justification is not relevant to these verses' subject, division is.
1 Corinthians 1:23-25
23But we preach Christ crucified, unto the Jews a stumblingblock, and unto the Greeks foolishness;
24But unto them which are called, both Jews and Greeks, Christ the power of God, and the wisdom of God.
25Because the foolishness of God is wiser than men; and the weakness of God is stronger than men.
When Jesus was crucified He became a stumbling block to the Jews. He was to be their King. How could He (our
(Jews) King) allow Himself to fall into the hands of the Romans? Hence forth the Jews stumble even unto today.
Unto the Greeks the preaching of the death burial and resurrection of Christ was foolishness because of His resurrection. They could not accept the idea of the resurrection, they had no teaching of any resurrection.
Acts 17:18-21,29-32
18Then certain philosophers of the Epicureans, and of the Stoicks, encountered him. And some said, What will this babbler say? other some, He seemeth to be a setter forth of strange gods: because he preached unto them Jesus, and the resurrection.
19And they took him, and brought him unto Areopagus, saying, May we know what this new doctrine, whereof thou speakest, is?
20For thou bringest certain strange things to our ears: we would know therefore what these things mean.

(For all the Athenians and strangers which were there spent their time in nothing else, but either to tell, or to hear some new thing.)
29Forasmuch then as we are the offspring of God, we ought not to think that the Godhead is like unto gold, or silver, or stone, graven by art and man’s device.
30And the times of this ignorance God winked at; but now commandeth all men every where to repent:
31Because he hath appointed a day, in the which he will judge the world in righteousness by that man whom he hath ordained; whereof he hath given assurance unto all men, in that he hath raised him from the dead.
32
And when they heard of the resurrection of the dead, some mocked: and others said, We will hear thee again of this matter.
Though the resurrection is not mentioned in 1:23 it is indeed implied as I have clearly shown that is exactly what caused the Greeks to react to Paul's Mars Hill sermon with mocking.
