They tolerate a total abandon of discipline and respect in the classroom and simply promote pupils from grade to grade without any regard as to whether they have mastered the subject matter. As a result we have a growing generation of youth who don't know what to think, let alone how to think. Many know that they were promoted and even graduated, not because they learned anything, but because the school system was preoccupied with how they felt about themselves. Many youth today are philosophically and spiritually adrift, because they grew up in a society where there seemed to be no objective values and standards, no objective ethics or morality, no objective truth. Ironically, instead of having high self-esteem, they have only the relativity of survival tactics as the basis for life.
Feelings are no substitute for faith, nor is affection a substitute for the truth.
That was true for Peter, and it is true for us. If Jesus had worried only about Peter's self-esteem, he would not have rebuked him. The church's task is not to get ahead of Jesus out of a sense of urgent subjectivity, but to follow him in objective obedience. It's the path you walk the rest of the week, suffering if need be for the sake of your neighbor. It isn't the surge of emotion you feel when you think about Jesus.
