Heard in a sermon that a theologian named Thomas Troeger suggested that Nativity scenes should be dynamic. The shepherds come and go and then for a long time the Holy Family is alone. Magi appear and go, instructed in a dream to go home by a different route than they came, avoiding murderous Herod. Then the Holy Family should move too, as Joseph was told in a dream to flee to Egypt, perhaps to a windowsill looking out on the suffering world Jesus came to save. It's powerful...!
