Catena Aurea · Lukasevangelium 2
And it came pass, as the angels were gone away from them into heaven, the shepherds said one to another, Let us now go even unto Bethlehem, and see this thing which is come to pass, which the Lord hath made known unto us. And they came with haste, and found Mary and Joseph, and the babe lying in a manger. And when they had seen it, they made known abroad the saying which was told them concerning this child. And all they that heard it wondered at those things which were told them by the shepherds. But Mary kept all these things, and pondered them in her heart. And the shepherds returned, glorifying and praising God for all the things that they had heard and seen, as it was told unto them.
How remarkably Scripture weighs the import of each word. For when we behold the flesh of the Lord, we behold the Word, which is the Son. Let not this seem to you a slight example of faith, because of the humble character of the shepherds. For simplicity is sought for, not pride. It follows, And they came in haste. For no one indolently seeks after Christ.
