Paul wrote to the Church at Corinth that had several problems. In Chapter 2, he is establishing the point that he is passing on God’s teaching rather than his own.

[i] My message and my preaching were not with wise and persuasive words, but with a demonstration of the Spirit's power, so that your faith might not rest on men's wisdom, but on God's power.[/i]

[i] we speak of God's secret wisdom [/i]

[i] God has revealed it to us by his Spirit. The Spirit searches all things, even the deep things of God. [/i]

[i] We have not received the spirit of the world but the Spirit who is from God, that we may understand what God has freely given us. This is what we speak, not in words taught us by human wisdom but in words taught by the Spirit, expressing spiritual truths in spiritual words. The man without the Spirit does not accept the things that come from the Spirit of God, for they are foolishness to him, and he cannot understand them, because they are spiritually discerned. The spiritual man makes judgments about all things, but he himself is not subject to any man's judgment: "For who has known the mind of the Lord that he may instruct him?" But we have the mind of Christ. [/i]

The same man, Paul through the inspiration of the Spirit, taught about keeping the Church pure from sin (1 Cor. 5); unity of the local church family (1 Cor. 3); proper use of gifts given by God (1 Cor. 12); love (1 Cor. 13); and so on. He also taught about proper local church government, a weekly collection, how to observe the Lord’s Supper communion and so on.

With all this teaching by Paul, why would one use Paul’s statement [i]“I resolved to know nothing while I was with you except Jesus Christ and him crucified”[/i] as a call to marginalize other teachings of Paul?
