In other words, the Christian alternative to the post-religious spirituality outlined earlier is not simply ‘religion’ as some sort of intellectual and moral system but the corporately experienced reality of the Kingdom, the space that has been cleared in human imagination and self-understanding by the revealing events of Jesus’ life. Standing in this place, I am made aware of what is fundamental and indestructible about my human identity: that I am the object of divine intention and commitment, a being freely created and never abandoned. Standing in this place, I am also challenged to examine every action or policy in my life in the light of what I am; and I am, through the common life of the 'Assembly’, made able to change and to be healed, to feed and be fed in relations with others in the human city. Faced with the claims of non-dogmatic spirituality, the believer should not be insisting anxiously on the need for compliance with a set of definite propositions; he or she should be asking whether what happens when the Assembly meets to adore God and lay itself open to his action looks at all like a new and transforming environment, in which human beings are radically changed.
