All that exists, and in particular all persons who exist, participate, by virtue of mere existence, in the existence of God. . . As [Catholic theologian Karl] Rahner explained, 'God does not merely create something other than himself-- he also gives himself to this other. The world receives God, the Infinite and ineffable mystery, to such an extent that he himself becomes its innermost life.' Human beings are the creatures who instinctively respond to that innermost life. 'This mystery,' Rahner writes, 'is the explicit and unexpressed horizon which always encircles and upholds the small area of our everyday experience . . . we call this God . . . However hard and unsatisfactory it may be to interpret the deepest and most fundamental experience at the very bottom of our being, man does experience in his innermost history that this silent, infinitely distant holy mystery, which continually recalls him to the limits of his finitude and lays bare his guilt yet bids him approach; the mystery enfolds him in an ultimate and radical love which commends itself to him as salvation and as the real meaning of his existence.'
