Dawkins is offended by the localism of Christianity and by the way that the evidences of Christianity tie in with its localism.
From the transcript of closing remarks, written out here: (I have silently altered some punctuation and capitalization.)
I would remind you that the world Richard Dawkins wishes to bring us to is no paradise except for the few. It denies the existence of good and evil. It even denies justice. But ladies and gentlemen, our hearts cry out for justice. And centuries ago, the apostle Paul spoke to the philosophers of Athens and pointed out that there would be a day on which God would judge the world by the man that he had appointed, Jesus Christ, and that he’d given assurance to all people by raising him from the dead. And the resurrection of Jesus Christ, a miracle, something supernatural, for me constitutes the central evidence upon which I base my faith, not only that atheism is a delusion, but that justice is real and our sense of morality does not mock us.
Yes, well that concluding bit rather gives the game away, doesn’t it? All that stuff about science and physics, and the complications of physics and things, what it really comes down to is the resurrection of Jesus. There is a fundamental incompatibility between the sophisticated scientist which we hear part of the time from John Lennox – and it’s impressive and we are interested in the argument about multiverses and things, and then having produced some sort of a case for a deistic god perhaps, some god that the great physicist who adjusted the laws and constants of the universe – that’s all very grand and wonderful, and then suddenly we come down to the resurrection of Jesus. It’s so petty, it’s so trivial, it’s so local, it’s so earth-bound, it’s so unworthy of the universe.Watch Dawkins saying this on Youtube here. You can hear the scorn in his voice.
If anything "gives the game away," it is Dawkins's derisive and purely subjective rejection of anything other than (in his words) a "deistic god perhaps."
There is no argument there. It just offends Dawkins's taste that God should reveal himself through a miracle, at a particular place and time, within a particular cultural context, to a particular people. To Dawkins, such divine condescension, in order to reveal particular doctrines and to save mankind, is "unworthy of the universe." (Whatever, precisely, it means for something to be unworthy of the universe.)
Thanks be to God, the true God, we do not worship Dawkins's Universe. We worship the personal God, the God who said, "When Israel was a child, then I loved him, and out of Egypt have I called my son." We worship a God who has always had a chosen people and who has deigned to speak to man at sundry times and in diverse manners, and in these last days has spoken unto us through His Son.
His Son, whom he sent down from heaven, and who was made man for us and for our salvation.
For man could not have been saved in any other way. The deistic god about whom Dawkins will grudgingly hear tell is not a God who saves. He is a god who won't interfere once things are set going. He is a god who lets man go his own way.
But we are sinners, and we need a Savior. And so the true God did not abhor the womb of a virgin. Notice that whoever wrote the Te Deum already understood the Richard Dawkinses of the world very well, hundreds of years ago. Those of us who take our Christianity for granted at times might wonder, "Why even bring that up? Why would Jesus abhor the womb of the virgin?"
Because it was "so unworthy of the universe." Because it was so petty, so local, so earth-bound. That the Eternal Son, the one who made all things, who, yes, set the constants of the universe, the Great Physicist, the Eternal God who is above and beyond all things, should come down from heaven and be Incarnate by the Holy Ghost of the virgin Mary, and be made man.
Richard Dawkins looks at that and says, "Ewww, yuck." He will not bow his stiff neck to worship a God like that, a God who would do that, a God who would come down. He cannot even do so when the whole point made by Lennox was that it is precisely such a God who gives us evidence that He exists and that He is a rewarder of them that diligently seek him. Yet should not the scientific mind be interested in truth, and in evidence of the truth?
It is not only because we needed a Savior that Jesus came. It is also because we needed to know more about God. God had already revealed himself in a number of those local ways that so offend Dawkins--by choosing the Jews, by signs and wonders throughout the Old Testament. But mankind needed to know more. We needed to know that He is Triune, that He loves us as individuals, that He wants us to be united with Him forever. We needed to know that He is our Father--not just the heavenly Father of a chosen group (which God had already revealed), but of us as individuals.
And so, the Gospel of John tells us, though "No man hath seen God at any time," nonetheless "the only-begotten Son, which is in the bosom of the Father, he hath declared him."
Moses could not look upon the face of God, and so God hid him in the hollow of the rock while He passed by and showed Moses His glory indirectly.
But God wanted to show us His face. And the only way to do that, to show the face of God to man, was to come down into the creation and to have a face--a real face, a literal face that could be seen and touched.
So God was born as a Jewish baby in a petty, local venue, and the face of the God who redeems was revealed to man.
Today, let us not stumble at that stumbling stone. Let us not be offended by the scandal of particularity. Let us come and adore the One in whom alone we behold the face of God.
O that birth forever blessed,
When the virgin, full of grace,
By the Holy Ghost conceiving,
Bear the Savior of our race,
And the babe, the world's Redeemer,
First revealed His sacred face,
Evermore and evermore.
