What does 1 Corinthians 2:2 mean?

In the previous verse, Paul reminded the Corinthians that when he first came to their town, he did not present the gospel to them with lofty speech or human wisdom. In other words, he did not call attention to himself by performing feats of verbal gymnastics as some entertainers of their day did. He did not wow them with a display of his great personal wisdom. Orators of that era were much like entertainers—and Paul did not want to confuse the compelling truth of the gospel with mere entertainment.

Now Paul adds that he made a conscious choice not to display his knowledge about anything at all except for Jesus Christ and His crucifixion. It is not that Paul did not know about anything else, of course. He was well educated and experienced (Philippians 3:4–5; Acts 17:1–4). At least for these particular people, Paul wanted to be sure they weren't attracted by spectacle or entertainment. His mission was not to impress them with all he knew and could talk about. Paul decided to focus on a simple, culturally radical mission: to deliver Christ's message to them.
