From the 2004 Christmas sermon by Archbishop of Canterbury, Rowan Williams:
We live from him and in him. The whole universe exists because God has not held back his love but allowed it to flow without impediment out of his own perfection to make a world that is different from him and then to fill it with love through the gift of his Son. And our life as Christians, our obligations, our morality, do not rest on commands alone, but on the fact that God has given us something of his own life. We are caught up in his giving, in his creative self-sacrifice; true Christian morality is when we can’t help ourselves, can’t stop ourselves pouring out the kind of love that makes others live. Morality, said one prominent modern Greek Orthodox theologian, is not about right and wrong, it’s about reality and unreality, living in Christ or living for yourself. Being good is living in the truth, living a real life, a life that is in touch with ‘the fire in the equations’ and that lets the intense creativity of God through into his world. The goodness of the Christian is never a matter of achieving a standard, scoring high marks in a test. It is letting the wonder of God’s love knock sideways your ordinary habits, so that God comes through – the God who achieves his purpose by reckless gift, by the cradle and the cross.
