Let me give you a definition of ethics: It is good to maintain life and further life; it is bad to damage and destroy life. However much it struggles against it, ethics arrives at the religion of Jesus. It must recognize that it can discover no other relationship of love. Ethics is the maintaining of life at the highest point of development — my own life and other life — by devoting myself to it in help and love, and both these things are connected.
