As I in hoary winter's night stood shivering in the snow,
Surprised I was with sudden heat which made my heart to glow;
And lifting up a fearful eye to view what fire was near,
A pretty babe all burning bright did in the air appear...
Alas, quoth he, but newly born in fiery heats I fry,
Yet none approach to warm their hearts or feel my fire but I !
My faultless breast the furnace is, the fuel wounding thorns,
Love is the fire, and sighs the smoke, the ashes shame and scorns;
The fuel justice layeth on, and mercy blows the coals,
The metal in this furnace wrought are men's defiled souls,
For which, as now on fire I am to work them to their good,
So will I melt into a bath to wash them in my blood.
With this he vanished out of sight and swiftly shrunk away,
And straight I called unto mind that it was Christmas day.

St. Robert Southwell, "The Burning Babe," 1595
