Pseudo-Chrysostom
Catena Aurea · Matthäusevangelium 19
Then were there brought unto him little children, that he should put his hands on them, and pray: and the disciples rebuked them. But Jesus said, Suffer little children, and forbid them not, to come unto me: for of such is the kingdom of heaven. And he laid his hands on them, and departed thence.
The flesh as it delights not in good, if it hear any good readily forgets it; but the evil that it has it retains ever. But a little while before Christ took a little child and said, Except ye become as this child, ye shall not enter into the kingdom of heaven, (Matt. 18:3.) yet His disciples, presently forgetting this innocence of children, now forbid children, as unworthy to come to Christ.
