May you have a blessed and wonder-filled season.
I wrote it years ago during seminary, when I was enrolled in a class on the history of Christian thought with Drs. Roberta Bondi and Bill Mallard (and sitting next to an attractive young woman named Sandy O'Quinn who I was not yet married to). We were studying Athanasius, who was very influential in the 4th century in clarifying the doctrine of the incarnation. He was well known for the idea that God in Christ came down from above that we might be brought from below.
For more on Athanasius see this article.
