Christum wir sollen loben schon

"Christum wir sollen loben schon" (We should praise Christ beautifully) is a Lutheran Christmas hymn with a text by Martin Luther, first published in 1524 in the Erfurt Enchiridion. He wrote it based on the Latin A solis ortus cardine and kept its melody. The hymn was used in several musical settings, including the chorale cantata by Johann Sebastian Bach, Christum wir sollen loben schon, BWV 121.
