Patristic Wisdom: The Nativity of Our Lord

So it was, when the angels had gone away from them into heaven, that the shepherds said to one another, “Let us now go to Bethlehem and see this thing that has come to pass, which the Lord has made known to us.” And they came with haste and found Mary and Joseph, and the Babe lying in a manger. Now when they had seen Him, they made widely known the saying which was told them concerning this Child. And all those who heard it marveled at those things which were told them by the shepherds. But Mary kept all these things and pondered them in her heart. Then the shepherds returned, glorifying and praising God for all the things that they had heard and seen, as it was told them. (Lk 2:15–20)

As men who were truly watching, they said not, Let us see the child; but the word which has come to pass, i.e. the Word which was from the beginning, let us see how it has been made flesh for us, since this very Word is the Lord. For it follows, Which the Lord has made, and has shown to us; i.e. Let us see how the Lord has made Himself, and has shown His flesh to us.

It seems to succeed in due order, that after having rightly celebrated the incarnation of the Word, we should at length come to behold the actual glory of that Word. Hence it follows: But when they saw it, they made known the word which had been spoken to them. That is to say, from the Angels, and had seen, i.e. in Bethlehem, as it was told them, i.e. they glory in this, that when they came they found it even as it was told them, or as it was told them they give praise and glory to God. For this they were told by the Angels to do, not in very word commanding them, but setting before them the form of devotion when they sung glory to God in the highest.

To speak in a mystery, let the shepherds of spiritual flocks, (nay, all the faithful,) after the example of, these shepherds, go in thought even to Bethlehem, and celebrate the incarnation of Christ with due honors. Let us go indeed casting aside all fleshly lusts, with the whole desire of the mind even to the heavenly Bethlehem, (i.e. the house of the living bread,) that He whom they saw crying in the manger we may deserve to see reigning on the throne of His Father. And such bliss as this is not to be sought for with sloth and idleness, but with eagerness must we follow the footsteps of Christ. When they saw Him they knew Him; and let us haste to embrace in the fullness of our love those things which were spoken of our Savior, that when the time shall come that we shall see with perfect knowledge we may be able to comprehend them.
