The Mystery of the Incarnation: a hymn and some quotes

I recently was introduced to the trio Ordinary Time. Their first album In the Town of David, ironically enough, focused on Advent. Towards the end of their set list, is the beautiful little hymn, Thou Who Wast Rich, written by Frank Houghton (1894-1972). I remember hearing it when I was little. The tune is beautiful and haunting. Below are the lyrics. Let the mystery of the Incarnation wash over you as you read and listen.

Thou who wast rich beyond all splendour,
All for love's sake becamest poor;
Thrones for a manger didst surrender,
Sapphire-paved courts for stable floor.
Thou who wast rich beyond all splendour,
All for love's sake becomes poor.

Thou who art God beyond all praising,
All for love's sake becamest man;
Stooping so low, but sinners raising
Heavenwards by thine eternal plan.
Thou who art God beyond all praising,
All for love's sake becamest man.

Thou who art love beyond all telling,
Saviour and King, we worship thee.
Emmanuel, within us dwelling,
Make us what thou wouldst have us be.
Thou who art love beyond all telling,
Saviour and King, we worship thee.

C.S. Lewis wrote quite a bit on the Incarnation as well. In my search for great Advent poems, I ran across this gem of a blog, which provided some great Advent-y quotes from Lewis.

The Eternal Being, who knows everything and who created the whole universe, became not only a man but (before that) a baby, and before that a fetus inside a Woman's body. If you want to get the hang of it, think how you would like to become a slug or a crab.

 C.S. Lewis, Mere Christianity, p179

He goes down to come up again and bring the whole ruined world up with Him. One has the picture of a strong man stooping lower and lower to get himself underneath some great complicated burden. He must stoop in order to lift, he must almost disappear under the load before he incredibly straightens his back and marches off with the whole mass swaying on his shoulders.

C.S. Lewis, Miracles, p148

The Incarnation was God's 'weak moment': when Omnipotence becomes a baby in a manger has 'weakened' itself.... The temptation...is precisely a temptation to evade the self-imposed weaknesses, to be strong, omnipotent, again - to make stones into bread, to be emperor of the world, to do 'levitations'. The weakness was the strength.

C.S. Lewis, Collected Letters III, p 409ff
