Hail the heav'n-born Prince of Peace! Hail the Son of Righteousness! Light and life to all He brings, Ris'n with healing in His wings. Mild He lays His glory by, Born that man no more may die; Born to raise the sons of earth, Born to give them second birth.

--Hark! The Herald Angels Sing (traditionally, the third verse -- starts at 2:52 in the linked video)

An unusual choice, to be sure. But notwithstanding the obvious religious content, I actually find this piece of the hymn to be a beautiful expression of genuine transhumanist sentiment. We've previously discussed how rationalism doesn't seem to leave much room for "Glory be to Gauss in the Highest!", but even if the sentiment of "highest praise" is a little Dark Artsy, I find myself thinking of something like a Friendly AI Singularity when I hear these lines. Sung in the right way, the song can actually give me chills to a degree rivaling HP:MoR -- you know, that chapter. Just listen to it from that perspective see if you don't find it inspiring.

I will note that I had a hard time finding a version of the song sung exactly how I wanted. It's usually performed slow, often by a choir, whereas I imagine it brisk, sung by one person with a deep voice, and with strong accenting -- as in, "Mild he lays his glory by/Born that man no more may die/Born to raise the sons of earth . . ."
