Bede the Venerable
Catena Aurea · Matthäusevangelium 2
Then Herod, when he saw that he was mocked of the wise men, was exceeding wroth, and sent forth, and slew all the children that were in Bethlehem, and in all the coasts thereof, from two years old and under, according to the time which he had diligently enquired of the wise men.
(Hom. in Nat. Innocent.) In this death of the children the precious death of all Christ’s martyrs is figured; that they were infants signifies, that by the merit of humility alone can we come to the glory of martyrdom; that they were slain in Bethlehem and the coasts thereof, that the persecution shall be both in Jerusalem whence the Church originated, and throughout the world; in those of two years old are figured the perfect in doctrine and works; those under that age the neophytes; that they were slain while Christ escaped, signifies that the bodies of the martyrs may be destroyed by the wicked, but that Christ cannot be taken from them.
