The answer to the Catechism's question regarding that humiliation contains many steps that seem to step down lower and lower, and go from bad to worse. Remember to look at these steps of humiliation from the perspective of being God and willingly condescending to it all.
Being born as a man
Belonging to a poor family, having a low social status
Submitting to His own law which was given to men
Experiencing and suffering through the various miseries of this life
Suffering God's wrath
Death
Of course our Christmas season seems to relate particularly to this first step of birth as a man. I think that some nativity scenes, plays and songs that we see and hear during Christmas time can give us the wrong impression or take our focus off the more significant considerations of Christ's birth. Its not really about cute little baby Jesus. G.I. Williamson references C.S. Lewis who compares Jesus' becoming man to a shepherd who becomes a lamb in order to sacrifice himself for the rescue of his flock. But that's not even a very good comparison, because the difference between God and man is far greater than the difference between man and beast.
Christ's birth leads directly to that next step of humiliation, being poor and of little reputation. The King of kings found himself welcomed into the world not in the world's grandest palace, not a mansion, not even an average room, but a stall for animals! As if God condescending to become man wasn't bad enough, this newborn God-man is treated as almost less than human from the moment He enters the world. If only that inn keeper knew that it was God's son that Mary was giving birth to. Of course we know that all of Jesus life on earth continued in this manner, never having material wealth and very rarely being given even an ounce of the respect and honor and worship that He deserved. Ironic how pagan Magi from the east honored Him more than most of the "God-fearing" people of Israel at the time. That always challenges me to check my heart on how I as a Christian value and treat people.
Can you imagine being God and having to submit to the law of Moses which was given to the people of Israel, sinful men and women just like every other human on the earth? I can see myself in that place, I'd be saying, wait a minute I gave these laws to Moses, I am beyond them. I created these laws for you people, and even better, I created mankind. How humiliating. Then think about the fact that Jesus followed the teachings and laws perfectly (of course He, did He understood them better than any human could) and yet He was still accused of breaking it many times during His earthly ministry!
Jesus experienced and felt the pain of the many different miseries a fallen world, under God's curse, has to offer. Hunger, rejection, loss of loved ones, betrayal, physical pain and many more. Furthermore, as the next step highlights, He bore the weight of the world's sin and was crucified. He took the place of those who did and would believe in Him, suffering the wrath of God deserved by all of sinful mankind. I think one thing that I learned in this book was the depth of that statement, the wrath of God. When Jesus came under that wrath on the cross, He experienced what it was like to have separation from God ("My God, My GOd, why have you forsaken me?"). God, more than anyone else knows how great He is and how much He and everything else depends on Himself and how wonderful it is to be in relationship with Himself. So the Son of God felt what it would be like to have separation from God so that those who place their faith in Him could instead have communion with God again. Sadly, but justly, those who will not place their faith in Jesus Christ will still face this wrath and judgment because they are not washed in the blood of the lamb of God. Instead of benefiting from the completed work of the Redeemer, they will face that unimaginable separation from the Author of Life.
In order to conquer death, Jesus had to go under its power first, which is what the whole three days in the grave accomplished. Thinking again from God's perspective (because contrary to other theories out there Jesus never emptied Himself of His divinity), can you imagine submitting yourself to death? That would be like being the best athlete in the world and intentionally losing a match to your greatest opponent even though they were no match for you. But you knew that you were still going to come out of it world champion in the end of the tournament so you let them beat you (I wonder if for a moment Satan thought he had won?). But as we know death did not have the victory because Jesus conquered the grave!
So, just remember as you think through this advent season, Jesus' birth was really the commencing of these steps of humiliation that He chose to submit to and endure. Why did He do this? Because He loved His creation, He loved us, and He wanted to restore the glorious world He had made made to once again be a theater of praise for Himself. The best gift God can give to us is Himself, and He has given that gift more than once in the history of creation despite our wickedness.
"How great is the love the Father has lavished on us, that we should be called children of God! And that is what we are! The reason the world does not know us is that it did not know him...
...The reason the Son of God appeared was to destroy the devil's work. No one who is born of God will continue to sin, because God's seed remains in him; he cannot go on sinning, because he has been born of God. This is how we know who the children of God are and who the children of the devil are: Anyone who does not do what is right is not a child of God; nor is anyone who does not love his brother.
This is the message you heard from the beginning: We should love one another

This is how we know what love is: Jesus Christ laid down his life for us. And we ought to lay down our lives for our brothers. If anyone has material possessions and sees his brother in need but has no pity on him, how can the love of God be in him? Dear children, let us not love with words or tongue but with actions and in truth...
...Dear friends, if our hearts do not condemn us, we have confidence before God and receive from him anything we ask, because we obey his commands and do what pleases him. And this is his command: to believe in the name of his Son, Jesus Christ, and to love one another as he commanded us. Those who obey his commands live in him, and he in them. And this is how we know that he lives in us: We know it by the Spirit he gave us."
(various passages from 1 John 2 & 3)
