Augustine of Hippo
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.
(Serm. 373. 3.) O blessed infants! He only will doubt of your crown in this your passion for Christ, who doubts that the baptism of Christ has a benefit for infants. He who at His birth had Angels to proclaim Him, the heavens to testify, and Magi to worship Him, could surely have prevented that these should not have died for Him, had He not known that they died not in that death, but rather lived in higher bliss. Far be the thought, that Christ who came to set men free, did nothing to reward those who died in His behalf, when hanging on the cross He prayed for those who put Him to death.
