What makes us humans is, of course, being more loving. And sin is a defect in this love. To say that Jesus was without sin just means that he was wholly loving, that he did not put up barriers against people, that he was not afraid of being at the disposal of others, that he was warm and free and spontaneous. That is what really lies behind the portentous sentence: ‘He spoke as one with authority.’ It makes him sound so magisterial and solemn. In fact it just means that what he said came straight from him warmly and immediately. He was never looking over his shoulder at the textbooks and traditions.
