"For I determined not to know any thing among you, save Jesus Christ, and Him crucified".
Please don't leave out the qualifying operning verse of this discourse:
"And I, brethren, when I came to you, came not with excellency of speech or of wisdom, declaring unto you the testimony of God." Yes, GB, that is how Paul came to the Corinthians, directly after being on the Athenian Areopagus where he tried to engage them in a profitable debate on the Unknown God, and was mocked the philosophers there and sent away as a rube.
But that is not how he went away, for while there he gave them what they needed to know about making disciples and starting a church. This letter was one of the followup epistles giving them yet more orders in how to diminish fractious effects and persons in their assembly.
And you might want to check out Romans 1, and see if The Gospel was not quite tightly sewed up with creation, hm?
