The beautiful simplicity of the Christian message is held before us today. When a scribe, a lawyer in our world, comes up and and asks Jesus what is the essence of the Law, Jesus replies that love of God and neighbour is the key. But Jesus emphasizes the point, going on to say that practical love is better than any sacrifice or show of piety.
Love is such a demanding thing. That is why it is so much more easy just to go to Mass and say that that is enough. Today, Jesus challenges us to look at these notions and see our real motives. Jesus always calls us to new places!
