The story of the sign given to the shepherds—the Child wrapped in swaddling clothes, laid in a manger—both recalls and anticipates other scriptural events in significant yet surprising ways. It also reminds us of our vocation, as those who must declare the good news of the sign of Christ to the shepherds of our age.
A competent sentinel must be vigilant, alert to and able to read the faintest signs upon a distant horizon, perceiving the most miniscule of details and discerning their greater import when they finally appear. In the opening chapters of both Matthew and Luke, we encounter a series of watchers and signs, presented in part as examples to the readers of the gospels in their own watching.
