"I do not think that modern science-- and the theory of relativity in particular-- provides us with any justification for moral relativity. On the contrary, our age is marked by a clear division between talk about science and talk about values. This means that moral responsibility cannot hide behind self-interested justifications. On the other hand, I believe that, even in the past, what has really counted, more than the weight of well-defined moralities, has been a process of ethical seeking, forever problematic and forever risky. A Christian too sure of himself about what is right and wrong has never, I believe, been a good Christian."
