1 Corinthians 2:2 "I resolved to not know anything except Jesus Christ and him crucified!" I find this both difficult and extraordinary advice. All too often, Christians think they have to know all the answers to all the questions. In my experience there are a lot of questions that have no available answers. I have found that there are a lot of questions that are an end in themselves (the question is the point). If we resolved only to know what we absolutely know -- Jesus is the Son of God, sent from God to offer his life on the Cross, be raised from the dead and ascend to heaven. Through the choice of becoming a follower of Jesus we receive the gift of salvation and eternal life -- we would not find ourselves in a lot of needless arguments over words, phrases and processes. Something to work on. . .
Now, having said that. Paul was an exceptionally well educated man who, as his letters clearly show, utilizes his learning and knowledge in his preaching and in his Apostolic work. So, don't think Paul is pretending to be some back woods preacher who claims to know nothing but the book. Paul quotes pagan philosophers and is well schooled in the use of rhetoric. He is profoundly acquainted with the Bible and is keenly aware of the political realities of his time. What matters is Jesus. What matters is how can we help more people come to know him!
