In seeking Christmas texts to set for the Creighton University Chamber Choir, I came upon a hymn entitled, "Sun of Righteousness", which had a beautiful trio of verses. I intentionally avoided reading or listening to the music of the hymn, but extracted the poetry and have composed original music to this early-17th-Century lyric. I also added brief "Hodie!" and "Gloria" responses to verses 1 and 2, harkening back to Renaissance tradition both in meter/tempo change and in form.
