Comfort, give comfort to my people, says your God . . . Like a shepherd he feeds his flock; in his arms he gathers the lambs, Carrying them in his bosom, and leading the ewes with care. (Is 40:1-11)

Händel’s Messiah opens with this prophecy from Isaiah with its promise of comfort. Saint Nicholas (270-343) followed in the footsteps of the Good Shepherd. He was known as a gentle, generous shepherd who cared for the flock entrusted to his care. Saint Nicholas has become one of the most beloved figures of Advent.
