Prior to the late nineteenth century, classical Christianity developed no social ethics. Rather, it concerned itself with self-purification. Christians needed only to be 'in a state of grace', unsullied and ready for the return of Christ. Muslims, in contrast, have always attempted to Islamicize the world. Today, many Christians and activist post-Christians are moving in that same direction. For them Christianity no longer entails a private practice of self-purification, but instead represents an ethical decision to struggle patiently and lovingly towards a new 'reality' in this life. In Creative Faith , Don Cupitt argues that Christians need to replace a heaven-obsessed theology with a new theology of moral striving. No longer should they aim to conserve the self, preparing for eternity: they must simply expend it, by living generously.
