GIA Publications has just published this choral composition based on an ancient Greek prayer, the Phos Hilaron. It is very appropriate for a choral anthem on Sunday morning (A morning text is included); and for college, community, and High School choirs, it would make a great way to begin or end a concert. You can purchase it from GIA.
Here’s a recording from our Advent Service at Baylor University:
