"Let us return to the question about God and about Christ as the centerpiece of an introduction to the Christian faith. One thing has already become evident: the mystical dimension of the concept of God, which the Asian religions bring with them as a challenge to us, must clearly be decisive for our thinking, too, and for our faith. God has become quite concrete in Christ, but in this way his mystery has also become still greater. God is always infinitely greater than all our concepts and all our images and names. The fact that we now acknowledge him to be triune does not mean that we have meanwhile learned everything about him. On the contrary: he is only showing us how little we know about him and how little we can comprehend him or even begin to take his measure. Today, after the horrors of the [twentieth-century] totalitarian regimes (I remind the reader of the memorial at Auschwitz), the problem of theodicy urgently and mightily demands the attention of us all; this is just one more indication of how little we are capable of defining God, much less fathoming him. After all, God’s answer to Job explains nothing, but rather sets boundaries to our mania for judging everything and being able to say the final word on a subject, and reminds us of our limitations. It admonishes us to trust the mystery of God in its incomprehensibility. Having said this, we must still emphasize the brightness of God, too, along with the darkness...
"The God who is Logos guarantees the intelligibility of the world, the intelligibility of our existence, reason’s accord with God, and God’s accord with reason, even though his understanding infinitely surpasses ours and to us may so often appear to be darkness. The world comes from reason and this reason is a Person, is Love—this is what our biblical faith tells us about God. Reason can speak about God, it must speak about God, or else it cuts itself short. Included in this is the concept of creation. The world is not just maya, appearance, which we must ultimately leave behind. It is not merely the endless wheel of sufferings, from which we must try to escape. It is something positive. It is good, despite all the evil in it and despite all the sorrow, and it is good to live in it. God, who is the creator and declares himself in his creation, also gives direction and measure to human action...
"When we separate Christ and God, behind this effort there is also a doubt as to whether God is at all capable of being so close to us, whether he is allowed to bow down so low. The fact that we don’t want this appears to be humility. But Romano Guardini correctly pointed out that the higher form of humility consists in allowing God to do precisely what appears to us to be unfitting, and to bow down to what he does, not to what we contrive about him and for him. A notion of God’s remoteness from the world is behind our apparently humble realism, and therefore a loss of God’s presence is also connected with it. If God is not in Christ, then he retreats into an immeasurable distance, and if God is no longer a God-with-us, then he is plainly an absent God and thus no God at all: a god who cannot work is not God. As for the fear that Jesus moves us too far away if we believe in his Divine Sonship, precisely the opposite is true: were he only a man, then he has retreated irrevocably into the past, and only a distant recollection can perceive him more or less clearly. But if God has truly assumed manhood and thus is at the same time true man and true God in Jesus, then he participates, as man, in the presence of God, which embraces all ages. Then, and only then, is he not just something that happened yesterday, but is present among us, our contemporary in our today. That is why I am firmly convinced that a renewal of Christology must have the courage to see Christ in all of his greatness, as he is presented by the four Gospels together in the many tensions of their unity."
