A few excerpts from a sermon by Quodvultdeus, 5th century Bishop of Carthage, on Holy Innocents day.
On what drove Herod to slaughter babies in Bethlehem:
Why are you afraid, Herod, when you hear of the birth of a King? He does not come to drive you out, but to conquer the devil. But because you do not understand this you are disturbed and in a rage, and to destroy one Chile whom you seek, you show your cruelty in the death of so many children. … You destroy those with tiny bodies because fear is destroying your heart.
On grace and martyrdom:
God has taken up the children of the enemy into the ranks of God’s adopted children. The children die for Christ, though they do not know it. The parents mourn for the death of martyrs. The children make of those as yet unable to speak fit witnesses to themselves. … How great a gift of grace is here! To what merits of their own do the children owe this kind of victory? They cannot speak, yet they bear witness to Christ. They cannot use their limbs to engage in battle, yet already they bear off the palm of victory.
