Hilary of Poitiers
Catena Aurea · Matthäusevangelium 18
At the same time came the disciples unto Jesus, saying, Who is the greatest in the kingdom of heaven? And Jesus called a little child unto him, and set him in the midst of them, And said, Verily I say unto you, Except ye be converted, and become as little children, ye shall not enter into the kingdom of heaven. Whosoever therefore shall humble himself as this little child, the same is greatest in the kingdom of heaven. And whoso shall receive one such little child in my name receiveth me. But whoso shall offend one of these little ones which believe in me, it were better for him that a millstone were hanged about his neck, and that he were drowned in the depth of the sea.
He calls infants all who believe through the hearing of faith; for such follow their father, love their mother, know not to will that which is evil, do not bear hate, or speak lies, trust what is told them, and believe what they hear to be true. But the letter is thus interpreted.
