The Corinthians proved to be the most trying kind of people—pupils who were confident they knew more than their teacher, children that were convinced they were better than their parents. Christians certain that they had left their apostle far behind. They had constructed their own religion for themselves, their own wisdom, their own spirituality, had brought them to the Kingdom, while Paul was still stuck fast in the mud. They knew it all, they had it all, they could do it all. It is an attitude that is always threatening to grow up within the Church, where we are all too much inclined to think that our own theological learning, our own warm-hearted piety, our own social activism, have created a Christian faith for whom Almighty God himself ought to be more than grateful.
