Love came down at Christmas,
Love all lovely, Love Divine,
Love was born at Christmas,
Star and Angels gave the sign.
Worship we the Godhead,
Love Incarnate, Love Divine,
Worship we our Jesus,
But wherewith for sacred sign?
Love shall be our token,
Love shall be yours and love be mine,
Love to God and all men,
Love for plea and gift and sign.
–Christina Rosetti
Daniel E. Gawthrop composed one of my favorite settings of this poem.
You can listen to it here. (Or try here, if you have trouble.)
