Early Moltmann on Eschatology and (not) Adapting to our Environment

"Christian eschatology in the language of promise will then be an essential key to the unlocking of Christian truth. For the loss of eschatology - not merely as an appendix to dogmatics, but as the medium of theological thinking as such - has always been the condition that makes possible the adaptation of Christianity to its environment and, as a result of this, the self-surrender of faith." -Jurgen Moltmann, Theology of Hope, p. 41
