19 As it says in the holy Writings, I will put an end to the wisdom of the wise, and will put on one side the designs of those who have knowledge.

20 Where is the wise? where is he who has knowledge of the law? where is the man of this world who has a love of discussion? has not God made foolish the wisdom of this world?

21 For because, by the purpose of God, the world, with all its wisdom, had not the knowledge of God, it was God's pleasure, by so foolish a thing as preaching, to give salvation to those who had faith in him.
