Even if we can envisage the social forms that a Kingdom of Love might require, is such a kingdom a pure ideal? Can love become a reality in a world such as ours, where even love itself is a source of human suffering and mutual affliction? Kant postulates an archetypal life of love that is humanly imaginable, but it seems it would take a near-miracle to realize the ideal. This is the miracle Christian theologians such as Karl Barth see in Christmas. The Christmas event, Barth argues is incomprehensible to human reason and we can only bear witness to it. Against this view, it is argued that the new beginning that Christians see in the Incarnation coheres with human experience, as in the ‘novelty’ of a new birth and the possibility of forgiveness. Yet, as the Christian Eucharist shows, this new beginning in history remains also a focus of eschatological hope.
