It would seem that Barth has the monopoly on Apocalyptic – at least more so than de Lubac.  However, the following passage from “The Development of Dogma,” made me think otherwise:

“We sometimes reason as if revelation had come simply to add a few bits of knowledge, higher or more hidden, to that which man already possessed or that he could at least possess by the fact of his reason.  He knew, for example, that God is one: he will henceforth know besides that God is also Trinity.  This way of seeing is superficial.  The irruption of the Spirit of Christ is something quite different!  Revelation, in fact, is at the same time a call: the call to the Kingdom, which is not open to man without ‘conversation’, which is to say, an inner transformation and, as it were, a recasting not only of will but of being itself.  Then the entrance into another existence is produced.  It is a new creation, which resounds in one’s entire awareness: it upsets the original equilibrium, it modifies the orientation of it, it opens up unsuspected depths in it.  Eyes open anew on a new world.  The community of a new life allows the giving of a meaning, its whole meaning to the divine object of faith” (Theology in History, 275).
