1 Corinthians 2:2

2. I determined not to know Rather, I did not determine to know. He had no purpose of holding forth any philosophical substitute for the Gospel. By this is not meant that a minister must preach on no other topic than the crucifixion of Christ. It is not meant that he may not in preaching denounce particular sins, or instruct in particular virtues. Nor is it meant that he may not preach the law, or draw lessons from Scripture characters or events even in the Old Testament. Nor is it meant that he may not devote entire sermons to particular doctrines not in immediate connexion with the crucifixion. What Paul meant was, that he knew nothing but Christ’s atonement no substitute for it in the systems and philosophies of mere men as a ground of salvation. His meaning was, as in 1 Corinthians 3:11, that there can be no other foundation than Christ.
