When the angels went away from them into heaven, the shepherds said to one another, “Let us go over to Bethlehem and see this thing that has happened, which the Lord has made known to us.” And they went with haste and found Mary and Joseph, and the baby lying in a manger. And when they saw it, they made known the saying that had been told them concerning this child.  And all who heard it wondered at what the shepherds told them.
Luke 2: 15-18

There is no specific “song of the shepherds” recorded in scripture.  They were unlikely people to be inspired to use flowery words and memorable turns of phrase.   Scripture says simply they looked at each other and agreed to get to Bethlehem as fast as possible and see for themselves what they had been told by God.   There was no time to waste singing out praises and thanksgiving;  they “went with haste.”

Witnessing an appearance of the heavenly host followed by seeing for themselves the incarnation of the living God in a manger must have been overwhelming to those who otherwise spent much time alone and in silence.  They must have been simply bubbling over with everything they had heard and been shown.  At least scripture does tell us the effect the shepherds’ witnessing words had on others: “and all who heard it wondered…”

I don’t think people wondered if the shepherds were embroidering the story, or had a group hallucination, or were flat out fabricating for reasons of their own.  I suspect Mary and Joseph and the townspeople who heard what the shepherds had to say were flabbergasted at the passion and excitement being shared about what had just taken place.  Seeing became believing and all could see how completely the shepherds believed by how enthusiastically they shared everything they knew.

We know what the shepherds had to say, minimalist conversationalists that they are.   So we too should respond with wonder at what they have told us all.

And believe as they do.
