Matthew 19:15

But since children cannot follow all things that are commanded them, Jesus laid His hands upon them, and leaving virtue in them by His touch, went away from them, seeing they were not able to follow Him, like the other more perfect disciples.

Also laying His hands upon them, He blessed them, to signify that the lowly in spirit are worthy His grace and blessing.

(non occ.) He laid His hands upon them while men held them, to signify that the grace of His aid was necessary.

The infants are a type of the Gentiles, to whom salvation is rendered by faith and hearing. But the disciples, in their first zeal for the salvation of Israel, forbid them to approach, but the Lord declares that they are not to be forbidden. For the gift of the Holy Ghost was to be conferred upon the Gentiles by laying on of hands, as soon as the Law had ceased.

But mark thou, I pray, how from some men's wicked doings, other men gain. I mean, that the Jews went away having learnt nothing, for neither did they ask with the intent of learning, but the disciples gained even from hence. "Then were there brought unto Him little children, that He should put His hands on them, and pray: and the disciples rebuked them. But He said unto them, Suffer the little children to come unto me, for of such is the kingdom of Heaven. And He laid His hands on them, and departed thence." And wherefore did the disciples repel the little children? For dignity. What then doth He? Teaching them to be lowly, and to trample under foot worldly pride, He doth receive them, and takes them in His arms, and to such as them promises the kingdom; which kind of thing He said before also. Let us also then, if we would be inheritors of the Heavens, possess ourselves of this virtue with much diligence. For this is the limit of true wisdom; to be simple with understanding; this is angelic life; yes, for the soul of a little child is pure from all the passions. Towards them who have vexed him he bears no resentment, but goes to them as to friends, as if nothing had been done; and how much soever he be beaten by his mother, after her he seeks, and her doth he prefer to all. Though thou show him the queen with a diadem, he prefers her not to his mother clad in rags, but would choose rather to see her in these, than the queen in splendor. For he useth to distinguish what pertains to him and what is strange to him, not by its poverty and wealth, but by friendship. And nothing more than necessary things doth he seek, but just to be satisfied from the breast, and then he leaves sucking. The young child is not grieved at what we are grieved, as at loss of money and such things as that, and he doth not rejoice again at what we rejoice, namely, at these temporal things, he is not eager about the beauty of persons. Therefore He said, "of such is the kingdom of Heaven," that by choice we should practise these things, which young children have by nature. For since the Pharisees from nothing rise so much as out of craft and pride did what they did, therefore on every hand He charges the disciples to be single hearted, both darkly hinting at those men, and instructing these. For nothing so much lifts up unto haughtiness, as power and precedence. Forasmuch then as the disciples were to enjoy great honors throughout the whole world, He preoccupies their mind, not suffering them to feel anything after the manner of men, neither to demand honors from the multitude, nor to have men clear the way before them. For though these seem to be little things, yet are they a cause of great evils. The Pharisees at least being thus trained were carried on into the very summit of evil, seeking after the salutations, the first seats, the middle places, for from these they were cast upon the shoal of their mad desire of glory, then from thence upon impiety. So therefore those men went away having drawn upon themselves a curse by their tempting, but the little children a blessing, as being freed from all these. Let us then also be like the little children, and "in malice be we babes." For it cannot be, it cannot be for one otherwise to see Heaven, but the crafty and wicked must needs surely be cast into hell.
