But surely that would be watering the wine? Isn’t it a question of everything or nothing? To be quite frank, the Either-Or people seldom appear to practice their own severity. Their uncompromising attitude often looks suspiciously like rhetoric. No, what the Sermon on the Mount demands is not everything or nothing, but a beginning and a continuing, a rising again and plodding on after every fall.
by Joseph Cardinal Ratzinger Romano Guardini
