Bede the Venerable

Again, the shepherds of the Lord’s flock by contemplating the life of the fathers who went before them, (which preserved the bread of life,) enter as it were the gates of Bethlehem, and find therein none other than the virgin beauty of the Church, that is, Mary; the manly company of spiritual doctors, that is, Joseph; and the lowly coming of Christ contained in the pages of Holy Scripture, that is, the infant child Christ, laid in the manger.
